I am retired now but when I was working, we used HP ProLiant servers, and I thought that back plane looked very familiar. Yes, those 2U G5's are kind of heavy. I often worked in very crowded server racks, so this one was refreshingly empty.

[@kkpdk]

Yup. I have a couple 380G5's in what I call the 'museum rack'. It has not been powered in years. Maybe I should plug in power and see if they still work.

[@markarca6360]

The servers are HP ProLiant DL380 G5 (that was before HPE (5 years ago, now it is Gen10).

Network tour would be great. Explaining where your feeds come in from the outside world, and how they get given out to the racks. And is your carrier neutral, how customers can pick and have the carrier of their choice delivered to their rack.

I did a cable schedule once in a small data centre. Had to trace every Lan cable from end to end from 12 rack cabinets, label each end of the cables and record it all onto a spreadsheet. Took me about six weeks.

[@stingray65b]

Thank you for taking the time to post this series of videos. Cage nuts were a great improvement over the old style racks with pre-threaded holes, which could get stripped (occasionally happened). Plus, the option to choose between different rack screw and thread sizes.

[@billycroan2336]

Try using a cage nut puller. There's a proper tool for putting in cage nuts and it's not your fingers. You can get it in a molded screwdriver handle style or a thin piece of sheet metal tool that often comes with racks. Alternatively, just use a zip tie. You can seat the first half of the cage nut with a finger and then stick a zip tie between the other side of the nut and the hole. Push it tight with one hand and pull the zip tie with the other to drag the other half of the cage nut through the hole. For extra style points use a second zip tie as a handle for the first

[@stingray65b]

@@billycroan2336 Thanks. I think there’s a miscommunication. I’m aware of the tool. I have one. It resembles a nail clipper, though wide and flat. Used it often. I wasn’t referring to a stripped cage nut. I’m talking about older racks that have a pre-threaded hole in the rail itself. If the threads strip, though rare, I’ve typically had to put a nut behind the tail. I ran into this scenario once or twice when I bought a used rack on the cheap that was manufactured before the advent of cage nuts. Obviously, if a cage nut gets messed up on a rack that uses them you just pop it out and squeeze in a replacement, as I believe you were conveying. While data racks employ cage nuts now. I believe many smaller audio-oriented racks still employ pre-threaded rack rails. Cheers!

[@simonfoxell6590]

Nice explanation. Just one extra procedure we carry out, The Pull Test. Once we have racked the server we pull it back out to it;s locking point (if it has one) while supporting the bottom just to make sure it is racked securely.

[@Cr41677]

gen 5's in 2019, is this just for the video? It is also worth noting that you can order fans for most switches that change the direction of the airflow so they can be mounted at the back of the rack

[@lordchive8944]

Racking servers and putting in cage nuts and drawing blood is like a sacrificial offering to the networking gods :)

[@alextassot]

Great job on the video guys. I'm sure it would greatly help some inexperienced tech. However, worth to note that before tidying-up your cabling with velcro, one must be sure there is enough slack to be able to pull the server and do maintenance. As an exemple, the server in U21 would lose power feed A were you to pull it out! That's a major no-no. Again, nice video nonetheless, thanks for sharing it

I have a couple of 1/4" steel rods I place thu the top hole of the U below, to form an 'X'. That makes it easy to rack Ears Only devices with a single person (and hold up those extra heavy 2U switches without tiring).

[@billycroan2336]

Try doing just one side first, loosely and letting the damn thing dangle diagonally for a second. Then pivot the other side up and put it screw in loosely. Then tighten both screws while supporting the back so it's flush. The process looks goofy as hell but it works.

The blue fans on the switch would suggest it should actually be hot aisle facing and actually sucks cold air through the rear (fans) so ports should have been facing rear (not front as you’ve installed).

[@stevecrisler4972]

Are the switches just held in place by the four screws in the front? No rails or anything supporting the weight in the back? Seems like a lot of torque on the face of the switch so was curious.

[@jshauns]

Steve, Yep - just the four screws in the front. Dont worry - they are plenty sturdy.

[@chumpmu1]

It’s really the bottom screws doing all of the work. The top ones are for redundancy…

[@billycroan2336]

@@chumpmu1 the top ones don't do shit. Other than only getting place if you bump into the bottom of it from behind. But that's really not much of a problem. The top ones are honestly a waste of time. When the torque finally does start to deform the ears, if anything I put screws on the top two BEFORE putting the switch in and then back threading those top screws TO PUSH the top of the ear out while I tighten the bottom ones to push the bottom of the ear in. It's the nail in the coffin of some already chinced up ears (or sometimes it's the rack itself that's bent) but it gets the job done

Why don't you have an automatic transfer switch per cabinet for those single PSU devices to ensure they have redundant power in effect? If you lose feed A currently, that's one of your switches or servers going down.

It wasn't that much different in 1990 but the wages where better and there wasn't many people in IT so you had to be 1st, 2nd, 3rd line support, software support and telecoms installers and support (the telecoms wasnt as easy as it is these days), then they started pushing school leavers in to the industry and the wages plummeted, now the job is more defined in to specialist in one field or another and the market is saturated. There wasn't all the different qualifications, university was just IT degree where they taught software programming and the only other qualifications where Microsoft certification and Novel networking and you had to have both certifications to work in the field. Every site was different with a mix of bnc and rj45 networks. I used to enjoy my job but left the industry to become an electrician and plumber when the wages dropped £25k-35k a year. (Dependand on the contracts you where assigned and locations). £40k was a bloody good wage them days when you could buy a house for £16k and lower.

[@Natedaskate]

I hate when people mount their switches at the front of a rack …. The I/O on servers and storage are at the back

[@marco2carriloo436]

because are using these olders g5 servers?

[@TheGrimeh]

Look at those wasted PDU sockets due to the server rails! To do this properly firstly use 1200mm deep and 800mm wide racks when mounting servers, mount both PDUs on the right next to the server PSU's and so the sockets are facing the back of the rack (tucked down the side) and add decent cable management for all the data cabling on the left side and add cable gutters to support the cables running from the front to the back. Also keep all cable lengths to a minimum to avoid excess cable just hanging or getting in the way. Great to see the earth pin locking IEC sockets though! Some advice from one data center manager to another :)

[@TD_JR]

Your definition of SDM is different than my experience with IBM - SDM was customer facing, on the phone quite often, dealing with the customer needs along with an architect and other executive staff. They rarely did hands on rack and stack - much less monitoring and ticket handling. On this side of the pond, you're more of a Data Center Tech/Analyst.

Fun fact about airflow. Air can be up to 90 degrees F and with proper airflow components will survive. Now that same component with air at 32f with zero air flow, those same components will not survive. Airflow is critical to component survival and longevity.

[@larskruse7575]

You're both correct In data centers often there are two uplinks (internet connections), depending on what you pay for. So, for critical infrastructure, it is quite common to provide two uplinks from ether different sides of the building or even from different providers (and of course still different sides of the building). Just to make sure your systems are running and online in nearly every situation. Edit: typos

usually red cables are for monitoring (alarms and logs), blue is for network connectivity (probably connecting to the tor switch)

Never used these rails. Cool. But I should think it might say "rear left", at least for the installer handling that end of the business. Nonetheless, looks like they are so angled as to be specific to each side of the rack?

[@someguy4915]

They are, you have the left and right rail and you cannot swap those, nor can you install them upside down, the G6/G7 rails (same parts) can be installed either left or right (but again not upside down) and I think the G8/G9 (same parts) can be installed in any way as long as you have the rear of the rail facing to the back of the rack. Those G5 rails are fairly easy to install but damn near impossible to remove again, especially when there's equipment on top and below the G5 rails so you cannot get your fingers in there... G6/G7 have two tabs you push to release it, works fairly well, G8/G9 have one tab you just push and it drops the rail right out, works perfectly. Most G5's I have had to remove required a wrench to push that damn clip back in to release the rails...

I worked security for a DC(datacenter) and ended up getting hired learning from escorts I did or watching videos such as these. The title for the job can go by many names as it's company based. A couple are NOC technician, data center technician. But in the details of the jobs, you're looking for things that detail the information you know. Some DCs have their tech maintain or monitor chiller information etc. And some have a different department for that as well. I don't have schooling on it but at the very least a know how for computer hardware is needed. Learn your copper terminations, learn fiber basics. If the company is looking to include splicing sometimes it is OJT otherwise it's easy to find videos on those as well the practice us harder to fullfill as equipment is expensive, but im sure there are classes for them. Rack and stack like this video etc. You may be able to get your foot in through a contractor who specializes in fiber. And doing that may even broaden your knowledge towards OSP etc. Some of those contractors are an alternate route you may take which can help you your career path. Best of luck

Some smaller businesses will use older used servers and equipment to save costs. For many smaller businesses, it's the difference between having a server and not having one at all.

In our datacenter we still have servers running all the way back from 2007 and they are still working with some of our most critical services. Maintenance costs are higher for them today compared to when we originally installed them but they are still a workhorse.
