Interesting video, but not knowing what an RPS actually was beforehand, I was expecting it to be a kind of UPS. As it's not, it would be good to see some of your views or even reviews on rack mount UPS solutions for a domestic setting. The usage would be to keep a Ubiquiti PoE switch running whilst it powers several PoE cameras, and to keep a NAS running to record footage.

I was under the impression it offered a UPS like capability. Since when he’s hovering over the menu it looks like there is a backup window. I’m not sure if that correlates to just total utilization or actual back up capacity. I would like to see both the switch and RPS unplugged to see if there was any period of time it would stay running.

Great job, I've used Crosstalk in the past to help me with my PBX phone server setup and issues and they always come through. Thank you for all the helpful videos you guys put out. Here at The National Youth Science Academy, we have never had a phone line or a system that worked correctly until we started working with Crosstalk. Thanks again.

One thing you didn't discuss is the fact that the RPS outputs DC power. This could give a slight battery advantage when running on backup batteries you aren't running multiple AC-DC converters. But even bigger than that, this new "standard" give Unifi the ability to release a UPS that could output DC directly meaning it wouldn't have to do DC->AC->DC conversions increasing battery life even more.

A few things to note:. If the power supply fails then you still need to replace the switch to fix the problem. A Cisco with redudent power supplies can be fixed by switching the power supplies. The switch never goes offline. The Cisco 9300 when stacked can draw power from another switch in the stack should the power fail on one the the other switches. Also Cisco doesn't ship the second power supply. You need to pay extra for that. Ubnt is a great value but some of their products are not enterprises ready. It feels like they are selling half baked products.

Yeah the battery backup not built in means you have to have 1U for the distribution of the power that can be done in a 2U ups with cables that are $2-3,- a piece. Also: when a PSU inside a switch fails and you want to fix it, you have to replace the entire switch, that means removing 48 devices from the network that means downtime, in a small office environment that is feasible but in bigger networks that might not be great or simply not possible (think a 24/7 production line or website hosting) Lets do replacement times, lets assume a rack with 3 or 4 x 48 port swiches, nice and full of cables on the front, a PSU fails. 48 port switch with redundant hotswap PSU's, 1 failed needs replacing: unplug the power cable; 20 seconds, remove the PSU from the slot, another 20 seconds, plug the new PSU back in: 20 seconds, total time spend: 1 minute, total downtime: 0 seconds. Same situation, but with this system: 5 seconds per RJ45 port to plug out, thats 4 minutes to unplug all the cables (lets hope there are no special ports with specific configuration on them that you might have to document) then remove the bolts that hold in the switch, another 1-5 minutes, remove the switch from the rack 1-5 minutes, install the new switch into the rack 1-5 minutes, tighten the the screws 1-5 minutes, plug in the power 10 seconds, let the system boot 1-2 minutes?, plug in that massive power cable 10-30 seconds. Time spent: 10-26minutes, downtime: 5-26 minutes. depending on cable density in the rack and the assumption you plug back all the cables in the correct location. It's great that it's easy to configure and looks nice and it looks good on paper, but for real networks that need to be operational 24/7 this is just not an option.

When looking at the device it looks like it is only meant for "limited" fail-over. It only provides 950w and the large Unifi switches are able to draw 750w. (I know that not many do that) but the dual UPS setup will only work if total draw is below 950w. It looks like it is made for one switch failure or smaller stacks of equipment. Not the total loss of AC power to primary supply.

@@lachokroumov There is no battery backup in the device, it can not power devices, only prevent that the "unifi device" dies if the power supply in the switch dies. what you are looking for is a UPS, that will run the device if power fails. A UPS is normally rated in VA or watt (for small UPS it does not really make a difference). If you look at a 1200W ups it will normally state runtime at certain load. Could be 5min at 50% load (600W) then you know that you use 200W the runtime will be 15min for you. (remember that your numbers are worst case for the equipment (full load) and real numbers are lower) if 15min is not enough you need to find either a UPS with a bigger battery or buy a "external battery pack" for the UPS. That is only supported for smaller pro models.

Great review Chris! But.. Please dont compare hot-swap PSU gear prices with Unifi redundant solution! If PSU dies in Unifi you have to take the whole thing out and replace it while the broken one is in repair. With how-swap PSU gear you just replace the PSU and you are finished! Thats why the price is lower in Unifi solution. It is not redundent for PSU failures - its just resundant for power loss and nothing more. That said, you cant compare prices like you were, its kinda not fair. But awesme job with your videos! Keep up the good work!

I use a datacenter that requires you to use redundant power. You can use a PDU with redundant power and plug your single PSU unit or you can use dual PSU devices. I ordered the USP-RPS to fulfill the requirement of redundant power. The DC does this to make it easier to do maintenance. They also use less power by not allowing UPS in the racks. The building has UPS battery backup and diesel generators. The batteries are just there while the generators power on. The down side of the USP-RPS as I understand it, is you can't power up a device off the RPS. You can fail over to it but if the device is off it will not turn on with just the RPS powered up. This is a big issue for me but I don't have any better options...

If your AC power supply dies, you STILL have to replace the unit. Failing over to DC input is nice, but it just kicks the can down the road. If high availability matters, you need to be able to swap out the AC power supply while the unit is running off the RPS.

The UDM Pro and Pro switches should be connected to both power and the RPS (Redundant Power Supply) for proper operation. Power is required for the devices to function, and the RPS provides redundancy in case of a power failure.

Unifi has such a good value now for the entire rack stack. It's just cheaper so have a spare switch laying there than to have redundant power. However, the one down side is that you will need to actually replace the device and have some downtime than just swapping out the power supply. So it's really a matter of business preference for what type of solution you can afford.

The little cable from the Ethernet Board is most likely for the RJ-45 Jack lights.

I have to say, i'm not a big fan of this setup type. If that main PSU were to fail for any reason, then the only way to fix the main PSU is to get a new switch, or just leave it on backup the whole time. If they had the main PSU as modular, and this one as redundant, then I can at least replace the basd PSU.

Same design like Cisco switches, proprietary cables for redundant power, psu not hot swappable (at least not for all of their switch line-up with such a DC connector

I have watched a few of your videos and they are quite nice and thanks for your time. So far I had a good experience with Ubiquiti products. I have to say, this product does not make much sense. Yes Cisco has the same thing. I assume, it was an attempt to lock people to buying more Cisco equipment with custom connector. It would have made a lot of sense if it would have provided low voltage DC power directly from UPS battery to improve efficiency. But without battery, I question its usefulness. Maybe it is a stepping stone for a UPS product. But then it uses a custom power connector incompatible with other brands which I do not like to see. Overall, I would have said, do not buy, in most use cases an automatic transfer switch would be a better solution. I understand the PSU failure case. If the application is critical like space shuttle, an airplane etc. which will crash if system fails, then I would understand the small extra cost for redundant PSUis not so big deal. But in such cases, having extra budget of few thousand usd/euro is probably also nothing. Luckily for normal use cases PSUs are more than reliable enough... In general power supplies are so reliable today that some companies give 10+ year (even lifetime) warranty to them. It would make much more sense to use an ATS system instead. Yes they are little bit more expensive but usually can support any(from different manuacturers) equipment which has a power socket/plug from any manufacturer usually up to a whopping 16A. Eg: shop.powerwalker.com/10120543.html?language=en I think your math is little bit off. Yes Cisco and Aruba are expensive. But you should not compare the switch vs switch price,. The question is how much an extra power supply add to the price. The 48POE switch has 660W PSU and 650W ATX PSU (which is more complicated to produce as it provides 3 voltages) can be found with retail price I also think that your review is somewhat misleading. You should have short circuited the PSU of your switch with a screwdriver :) and then document the actions you needed to take to rectify the issue. Turning the power off is not testing the PSU failure, it tests power failure. Maybe an actual PSU failure in this product may take out the RPS system also. Who knows? In addition, the user is penalized if they buy 1-2 unifi devices then the USP-RPS which can power 6 devices. There is much overhead in the cost. On top of that, if you have your devices in different racks, well too bad for you. In addition, if you mix devices from different brands you won't be able to use the same RPS unit. Also, lets say the built-in power supply is actually broken in your 48POE switch. You have no choice but to change the whole switch. Hmm? But power supplies rarely get broken so maybe Ubiquiti is relying on that. Here is a hot swappable example which has similar pricing: (although they cheat on the power budget, it is half of the advertised for single PSU) www.fs.com/de-en/products/115386.html?attribute=5271&id=205749

I still prefer the unifi switch l2 POE with dual PSUs - this option with the RPS just means you have an extra device between the second circuit UPS and the devices. Also if the primary power supply fails in any of the devices, you can't just spend the $115 for a new PSU, you have to replace the unit (or fix it with a third party part)

Question. When these were still in Beta, Ubiquity indicated that this would only be able to power one device at a time. When you get your other cable can you verify that it can power more than one device? Also, what is the max power output? Can it handle multiple switches with POE? Thanks.

Personally I'd much rather have two hot-swapable bays that comes with one hot-swap power supply and if you want the second buy it extra.

If you cant swap the power supply in the device that want down without shutting the device down what good is it?

Chris can you tell me the depth of the RPS power connector, including bending the cable up/down. I have a wall mount rack and with the 48 port POE Pro switch, there is only 2" between the back of the switch and the wall, wondering if that large connector would fit with bending the cable up or down, or if I'd have to cut a hole in the wall for the cable bend/radius/depth. thanks

We don't use switches with redundant PSU in the datacenter, but we do use redundant stacked switches with duplicate connections to servers, and unfortunately unifi does not allow LACP over multiple switches. Just like the fiberswitches, the network is completely redundant. So if unifi would enable 'stacking' (could be done via the 10 gbit connection) and then allow LACP over multiple switches, it would do the job

Interesting approach to redundant power... With this proprietary solution UI gets a lot more profit than if they used 3rd party hot swap PSUs. Also most SMB solutions don’t have 6 devices in one location (closet). And finally for the SMB solutions with multiple device locations this proprietary RPS solution would actually cost more than redundant PSUs in each device especially with 1 or 7 devices in a location. These issues combined with the fact that replacing a failed PS in a UI RPS enabled device requires downtime and swapping the entire switch/device really limits the usefulness of UI’s redundant power solution. While I appreciate UI offering power redundancy the profit margin appears to have steered the solution offered. Can’t completely blame them for wanting more profit but this decision has limited the usefulness and cost effectiveness of redundant power for some customers. But it is great to see UI continue to add more enterprise features to their products. Like Chris said they are not designed to compete with the feature set of other enterprise solutions costing way more, but UI continues to get closer with each new product line. Great review Chris!

I have spent close $2500 or just under on Ubiquiti hardware ranging from Switches, AP’s Cameras etc and I run a 700Watt APC UPS that keeps things safe and battery backup when power goes out etc I run 3 of them not all for the Ubiquiti gear but also one for my main desktop and the entertainment equipment so around $800 on battery backup

Just been watching your video regarding the RPS. I think my favourite setup with e.g. 4 pro switches would be to have a RPS in front of a UPS with a big battery capacity and then have the primary power source to each of the switches coming directly from the grid i.e. no UPS in front of that source.

The little wire going to the board with the Ethernet is for the reset button.

Interesting idea. I see two issue. 1. If the PSU in the switch fails it will require the switch to be pulled instead of simply pulling and replace the PSU. 2. A UBNT switch could be sold with a single PSU leaving a bay open for an optional redundant PSU. This will allow either PSU to be replaced in the event of a outage without pulling the switch causing an outage. When I had the responsibly for such things I always had spares. Switch, HDD/SSD, PSU for everything in the server room/closet. No need to wait for the RMA.

So in the best case, thats an additional $90 per device for a shared hot spare PSU, at half capacity an extra $152 per device. I can see what they are trying to do, but in my opinion by not making the primary psu hot-swap they remove ⅔ of the value

This is good and I would probably put this in my home. For enterprise deployment, most would require hot swap parts.

Yet they still don’t allow storage flexibility and additional drive options. Proprietary connectors are frustrating though.

Can devices be configured to draw from the RPS by default and use internal psu as fail-over? This would increase overall efficiency and lower device wear.

"Don't turn it on ... _Take it apart!"_

Great video Chris, I have been waiting to see this in action before I bought one. Thank you for the great content

Itis a nice idea and would be ok, but it could be taken so much further. You could get switches with two of the RPS power connectors and no internal power supply. You then get two of the RPS units, each actively powering three units and providing backup power to the other three .... Now I can relocate all the heat generation from power conversion into those two units and cool them. You could also take it to the next step and add a power tansfer cable between the two RPS so if their incoming power is disrupted the can cross-power each other. Add some UPS units adn you could have some nicely redundant systems.

Well.Thank you. Now I know I have misunderstood RPS with UPS. I should have watched your video earlier.

One thing you didn't mention, or test, is that this device CANNOT COLD BOOT a switch or UDM-Pro/SE that has a failed power supply. In other words, if the connected Switch's internal power supply fails and the USP RPS takes over you are fine as long as it doesn't also lose power. However, if the USP RPS subsequently loses power, then you completely lose the switch AND you cannot power it back on using just the RPS. A bit of an oversight on UBNT's part in my opinion but still better than nothing I suppose.

It's a poor solution from the end user perspective though good for the supplier. That'sa shame - until now Ubiquity has seemed good at making things work well for the user. With the RPS when the psu in your switch fails, yes the RPS keeps it going, but you still have a switch that is faulty and has to be taken out of service to repair it. It would have been far more pro-oriented and customer-friendly to have two slots for hot swappable PSUs in the pro devices, anyone who wants redundancy can have both populated, or for economy keep one PSU on the shelf as a backup for a number of deployed switches. Bad choice of strategy by Ubiquiti, as it lowers their value to the customer, and lowers their reputation for pro-friendly design.

In this way, rather than making the switch a few hundred dollars more with two PSUs you sell the base unit cheaper to everyone and then those that want redundant power pay for the RPS. Also, two PSUs in the switch, router, or nvr will take up physical space in each unit. Since this is a DC supply...the power from it is connected directly to the device it is powering making the only needed space in the chassis one for the connector itself....of course you eat up 1U of space in the rack...but it sure makes design and manufacture of all the supplied units that much simpler and cheaper.

dodeca hedron I ordered one, hasn’t arrived yet. I have a DreamMachine Pro and the new 48 port POE switch, both with RPS connectors. I have 2 different circuit breaker panels, one is backed up by a generator. will be using a circuit from each, into a UPS, then one to the AC supplies, the other to the RPS.. That’s plenty of redudancy for me. Pretty much guarantees power to the network until generator runs out of fuel (has a 1,000 gallon underground propane tank, not too likely unless it’s the Zombie Apocolypse, then we have bigger issues)

IMO: the price of those cables COMBINED with the price of the USP make it not worth the cost. I would rather have separate PSUs in the units themselves. Redundant power supplies are not that expensive (you were comparing the already known to be expensive hardware with ubiquity, which is KNOWN to be cheaper. Those other companies hike the prices because there was no competition, not because of the feature set). Where this could excel however would be just dropping the internal PSU all together. Much like you power poe devices off of one plug, powering 6 switches off of one (or two) plug? Even better if they make the cables daisy chain/able to be paired with another of these units.

Good video but heads up for those watching, Ubiquiti hardware/software is not "Enterprise grade" as he mentioned. Enterprise grade hardware is Aruba, Cisco, Fortinet, Checkpoint, Palo Alto etc.

Absolutely agree

The Cat 6 cable tiny inside board is probably a surge protector.

Thanks for the video! It would be awesome if Ubiquiti would consider making an EdgePower with redundant hot-swappable power supplies, like the EP-54V-150W but for 24V, so that one could provide redundant power to EdgeRouter and EdgeSwitch devices that use 24VDC input. Would be great for WISPs and micro-pops or relay stations imho. The EP-24V-72W definitely has its use cases too, but it lacks redundant AC power input.

The Unifi US-16-XG has wide input DC connectors on the back and the USW-Flex-Mini has both PoE power and USB-C power. Maybe add these to your reviews for potential redundant power solutions. If you are looking to run multiple switches in a rack, you are going to want at least a US-16-XG, granted this is older generation at this point. If you have redundant firewalls, well they can't both plug into the single port the ISP provides, so need something in-between, but only need a few ports. Does it make sense to use a cheapy 5-port dumb switch and then at some point have it glitch up and you are either dead in the water or you have weird packet loss issues you can't figure out down the road? Does it make sense to buy a large, expensive switch with many more ports than you will ever use because it has redundant power supplies? Or would it make more sense to use a USW-Flex-Mini with PoE power from a managed Unifi switch with just say the management network available over it and the remaining ports only doing the Internet VLAN while also having cheap USB-C power going in for redundant power?

Nice video tks! Does anyone can tell me what kind of screws you use in this rack (like the on you use at 5min50s ? I'm searching for a solution with screws you can manipulate without screwdriver :)

THE U-NVR have access to it also..:) I think the LeaF has too.. and also the cloud key(if the rack mount for cloud key gen 2 works the same way)🤓

Great presentation, Chris. I agree, great concept, too.

Chris, I came late. I don't get RPS. Why not just use a UPS and be done with it? in a small office it will at least give you time to do a proper shutdown. Just watched the first 5.5 minutes I missed. I see it now. Very good idea. you can buy 1 RPS and 5 cables instead of 6 add-on power supplies. good idea.

It's for A and B power.. But I don't get why it has to be external.. Another large cable to clutter..

@@daveolson9424 most likely to save cost on the base unit itself. In this way, rather than making the switch a few hundred dollars more with two PSUs you sell the base unit cheaper to everyone and then those that want redundant power pay for the RPS. Also, two PSUs in the switch, router, or nvr will take up physical space in each unit. Since this is a DC supply...the power from it is connected directly to the device it is powering making the only needed space in the chassis one for the connector itself....of course you eat up 1U of space in the rack...but it sure makes design and manufacture of all the supplied units that much simpler and cheaper. I copy this from Giovanni Mercuri's comment thx

Yes. I like your diagram sent to me on redundant power!

i wonder what the function is of the Internal USB port inside the USP-RPS

Consumers who buy Ubiquiti's system components need to have a backup power generation system in case of power outages. For instance, let's say there is a mega-storm that has taken down power for several days. Without some on site emergency power generation, there is no solution to keep power to the system supplied. It is more than possible that this scenario is characterized as "WHEN" not "IF". It will happen sometime. A hurricane, tornado, fire, snowstorm, or other natural disaster must be considered as part of emergency management planning. With a whole house (or building) Emergency Power Generation System, along with the requisite switch over equipment, that should fill the need for the required, necessary and even vital power supply solution. If a Ubiquiti customer has shelled out big bucks for their system, it must be supplied with reliable power and backup power availability. Otherwise, what's the point?

That's not a molex power connector, its a IEC320C13.

Hey Chris! Great video! I just bought a UDM Pro, Gen2 48-port POE switch, and a USP-RPS. Would I only plug the UDM Pro and the switch into the USP-RPS.... or would I plug both into the USP-RPS AND the regular outlet? Thanks!!

So, I'm confused. Does this only help if the PSU in a switch or UDM dies, but not if there's a power outage? I didn't see any batteries in the case, but was under the impression that this was a type of UPS, which it appears it is not?

Could you liste dowen the maximam power consamtion of each devaice used in data center

3:25 - unboxing is my favorite part of your videos. Heehee.

As far as the price argument goes, with 6 switches it makes sense. With 1 switch, or 7 switches, that you need RPS on, not so much.

Yea I agree

in my case i don't need this RPS... but if i need redudanty Power Support i don't use anymore Ubiquiti... in real.. i think a bigger UPS is cheaper, and a Spare Switch in case of power supply goes down, can be a cheap one, or i have a other place where i can set a cheaper one and bring this sparepart. ive run years in networking... i have never a fail with Power behind a UPS

This channel has taught me so much.Thank you 🙏🏾

Like a billion other people said, for REDUNDANT power, they could have just done the "we have two ports but only give you one PSU" thing that literally *everyone else* does. If they're going to make a big-assed rack-mounted piece of gear, they could have at least put a freakin' BATTERY in it!!

So this RPS unit only works with the PRO switches correct. There’s no way to use it with the other rack mount switches that don’t have the Pro name attached?

Thanks for the review. Saw in a previous video in which the it showed the USP-RPS and I was wondering what Ubiquiti gear was that. For a RPS it's at a reasonable price and it's something that I will probably add to my network setup.

So without redundant power, do you have to buy a USURPS for your USP-RPS?

This is a dumb idea. Eaton sells redundant power switch technology, with this USP-RPS requires you to own two battery backup units on main, and your backup. I'd suggest getting a gas generator instead.. higher power to weight ratio.

I was going to go out out with the lads but the power went down down so I had to stay in in ;)

I know Cisco Systems have done the same thing before because it reminds me of the Cisco Systems' Redundant Power Systems.

I personally would rather have something like the second PSU being modular. Something you could buy later, slide in, then plug directly into 120v outlet. In those scenarios where switches are not in the same location, but desire redundant power then would potentially make this solution more expensive than competitors.

I installed an RPS and connected it to a Unifi Protect NVR. I pulled the NVR’s main power cord out and it stayed on so physically it appears to be working. However, I can’t seem to adopt it into my Unifi Elite cloud controller. The RPS seems to require a controller on 5.12.x and Elite is still on 5.11. Anyone else have this issue?

I don't get it?....If this isn't a UPS then what's the benefit.....(can someone please educate me?)

Is there a notification if power to the USP unit is interrupted? In my case primary power to switches will be via Cyberpower UPS, and this unifi USP will be backup if the Cyberpower runs out.

I think even tho I only currently have the UDM-Pro that would work with it that I would still buy it. Being that the UDM-Pro is my only router and controller having the power supply fail just once and the RPS there to keep us afloat till I can get a replacement IMHO is worth the money. Also I have a hunch that Ubiquiti only putting this on the Pro versions of the equipment is there trial run to see how it fairs. I’m thinking it may be something we see on all the equipment in the future.

What happens actually in case of power failure if you have a setup like that Visio diagram. How does UniFi USP-RPS know if a switch draws full 750W (e.g. full number of POE++ cameras connected) and is pulling on the edge or only the minimum? Does the UniFi USP-RPS start to smoke when the first circuit battery is empty or does it power only 1 switch while all switches scream for power? I think without a smart communication between UniFi USP-RPS and drawing devices the entire concept is useless!

is there a recommendation on the UPS that would be needed to battery back up the device? Does it need to be a pure sine wave? what would be an appropriate voltage?

I'm a ubiquiti fan but this design is severely flawed. No hot swappable psu where one can be taken out and replaced. If the main psu goes down, in order to get it fix there's going to be extended outages.

Dear @CrosstalkSol What is the brand of the rack or can you guys recommend good options. It looks completely fit for the purpose.

It is a very interesting product, BUT, without a battery for UPS type power backup I think it drops a bit short. I could se this, if you had a bit of mone to throw around, as a backup in several network cabinets to ensure the network stays up if there is a blackout keeping things as cameras, network equipment and NVR running. Nah, this is a little bit of a swing and amiss for me unfortunately...

Those cables look a nightmare to route. If they wanted to save money/allow flexibility, they could have put in a connector and a blanking plate. Then people could have bought either a secondary PSU as a backup (they could do the same with the main PSU to allow hot swapping I guess) which they could plug in or a module to allow the RSP to be used. Personally it looks to more a sales dept orientated product or an afterthought to offer the “full solution”.
