Dude exactly. All that cable mgmt and then you terminate without testing? Yikes if a cable is improperly terminated.....no labeling either. Still a very cool video tho.

I didn't see you test the patch cables. Not even a continuity test. That's confidence for you.

Great job! One suggestion for you from my bag of tricks. Once you measure out the length from the loom to the server, cut a "reference" length of cable from the box the same length. Now you have a measuring stick so to speak to cut the other sever cables the exact same length exiting the loom. Then the install will then look very neat.

Thank you so much for providing us such high quality and real time information.

That cabling at the end is so calming.

Once you've determined the first cable length, it makes more sense to go back to the office sit in a nice chair, put on some music and make the rest of the cables. On nice days, I even go outside and catch some sun while making cables. And leave a decent sized service loop!

That's pretty much exactly what I do, just sit at my desk with a box of cable and terminate and test. That feeling you get when the tester is like bink, bink, bink, bink, bink, bink, bink, bink. Feels so good. The worst is when it's the eighth wire and instead of bink it's bork! Ugh lol.

You cut the cables to the exact length to reach the server ports when racked. Presumably, you plan to tuck-in the power cables just as neatly. Looks beautiful, but... How are you going to slide a server out on the rails now? Must the customer have a unit down, just because a redundant, hot-swap fan needs replacing? You need some cable-management arms on the back to get the best of both worlds: no hanging, slack cables *and* on-line servers still able to slide out.

Welcome to paid-by-the-hour remote hands service. I agree though, you can buy patch cables from most decent places in approx. 4U increments. Also, you have to disconnect these wires to pull out the server and they had a ton of waste, with CAT6/7, that adds up quick. I'd leave at least the depth of the server in slack so you can pull it out, swap RAM etc I personally like to keep power cords on one side and network on the other, it seems they went with all wiring on the same side. Do like the loom tool though, may want to invest in one of those.

Very neat and clean install! Makes me want to start re-wiring and re-dressing the cables in my racks at work. I did notice, however, that you didn’t leave enough cable in the back to completely slide the server completely forward on the rails while it’s in service. When I do a rack I always factor-in the need to change a fan or add/change an internal component at some point in its lifetime and wire it so I can pull it out while it’s still running. That’s one thing I like about Dell EMC-they actually have n arm that attaches to the back of the rail that’ll hold the cables and ensure that you can do that. Just food for thought!! Again, very nice install!

Making the cables is going the extra-mile. I have to respect you for that.

@alexanderlinke2240

I think the rails are still there for ease of maintenance. I mean depending on the server type things that you can hot-plug like e.g. disks are often accessible from the front or back directly. All other parts you typically cannot maintain while the machine is online anyway. So you'd plug out electricity and ethernet and then start to replace/add components to the server. However you can still do this without completely taking the server out of the rack. Just pull it out the server on the rail, open the chassis and replace the parts.

Rails with cable management arms are great for keeping the cables super neat and enabling the server to be slid out. A cable tester could have been used and not added much time, but been another report for the customer to see (a quality tester will be able to have a report per cable). Something like a fluke link runner (I use an AT2000) will do this while one end is plugged into a switch. Qualifying it for gig speed.

@@anthonypolsinelli1179 On the other hand cable management arms can impede airflow quite a lot. I'm currently in the process of removing all the arms from a 5-rack HPC. It's a pain, but in this case the arms are quite full (redundant power + redundant network + redundant Infiniband + IPMI = 7 cables per 1U), and the machines do really run several degrees cooler without them - which means they will run at higher clocks. I'd recommend arms only for 2U+ servers.

nicely done but i would have gone with premade cables, you can find every size you need and use some cable management arms. i can make cables with little to no errors but crimping 20+ of them just seems like a waste of time since premade aren't that expensive. also don't cut the cables exactly in size leave a bit of slack in case one fails and you need to re-crimp it. your way looks cleaner but you can't remove a server without unpluging it, maybe that's a concern down the road. and of course velcro is a must to use.

I agree with you but I think in a Datacenter that doesn't apply really. First of all let's agree on the fact that a server in a DC has to have an uptime of 100% (except of course for the be weekly windows update or some patching that requires a reboot, or maybe a dedicated software that has some issues). Then, if you don't have any connectivity and you need to have access to a serveur, you can go plug yourself on the back or if there's a KVM you can use it too. So beside that, the only time you will pull those servers is in an EOF cycle. Also, if you suggest a hardware issue, the "most common" issue is regarding the SSD/Hardrive having an issue or a raid controller having an issue, in those cases, no need to pull the server you can hot swap those) Remember that those servers are top of the line servers (full RAM, bi processor, dual power supply etc). I've honestly never seen a top of the line server have a critical hardware issue and it's even true in the recent years. That's what I think, thanks for your comment.

The other issue I have with prefab is when the server guys run cables and they pick up a 20 ft instead of the 15 ft they needed. Especially with big builds space is at a premium. And decommissioning becomes a nightmare. But for small enterprises with a dozen servers than yea dont waste time patching. Just depends

Question: If you have to pull out the frame without disconnect the cable or you want to change a connector how you do that? You have to leave a service loop! Bundling cable is not that hard you just need some practice.

I had to design and implement such a network project for one our customers. It was a oil plant and the heat was unbearable in the server room. They had switched off power for some parallel electrical work. The cabling part is a nightmare even though I had a technician to assist me. Adding to that we had tremendous pressure from customer to get it over within 3 days. When it was over and I checked the network we were facing a loop in one switch. It took me another day to find and fix it. It was due to a wrong cable tag. I sweared I will never go for site implementation again after that episode..I really appreciate these engineers

I crimped hundreds of cables, in the wild. But in a DC: in my opinion a no-go. No quality assurance, even not a good idea with a Fluke tester, very expensive manual labor and you can redo your work when replacing the server in a couple of years for whatever reason. So, my preference: a longer stock cable with a loop.
