What do you have in your datacenters' toolbox?
Greetings My Ten Thousand Closest Friends, I have a requirement to stock an actual, physical toolbox with power tools, drill bits, and other useful accoutrements one would use in a 'typical' datacenter. Can any one recommend brands/models of (preferably cordless) power tools they've used successfully? Reading Amazon reviews is killing my few brain cells that remain. Any "and you should think about stocking $X, $Y, and a couple of $Zs in your tool chest" you could impart on the list (besides the right kind of cage nuts and enough rj45 jacks)? I have that sinking suspicion my comprehensive list is not comprehensive enough. I get one true shot at this as the datacenter is very, very far from any 1st-world suppliers[1] Very grateful for any cluebats you are able to spare on this (marginally off) topic. Best, aaron.glenn [1] Hargeisa, Somaliland; if you must know.
Generically, pack for the worst case. Screw extractor bits are invaluable when you need them. Whatever drill you choose, either make sure you can charge it where you go or bring a transformer. Small screw drivers, kobalt 4" diagonal cutting pliers, and rubber mallets have gotten me out of trouble. — Sent from Mailbox for iPhone On Sun, Mar 10, 2013 at 5:19 AM, Aaron Glenn <aaron.glenn@gmail.com> wrote:

Definitely yes. And let me suggest that while buying an off-the-shelf kit will probably suffice for most uses, there is one a la carte addition that I strongly recommend: Quikclot. It's (relatively) expensive. It's worth every penny and ten times more the first time you need to use it.

[WEG] The rule of thumb for most places I've worked has been that power screwdrivers are only acceptable for *removing* screws, at least where the electronic contents of a datacenter are concerned. Using a power screwdriver to install/tighten machine screws carries a nasty risk of cross-threading, or stripping, or snapping the heads off of the screws on something important, leading to unrecoverable problems with expensive modules that you can no longer easily remove to replace when the need arises. And Mr. Murphy says that the one with the damaged screw will be the first to fail. But then, most decent power screwdrivers have a torque clutch with settings to prevent such things, and everyone always uses them properly, right? ;-) Wes George This E-mail and any of its attachments may contain Time Warner Cable proprietary information, which is privileged, confidential, or subject to copyright belonging to Time Warner Cable.

Given that you are stocking exactly one toolchest in a 3rd world country, and you only get one shot at it... Depending on your budget and how many people will have access to these tools, you might consider getting 2 or 3 of everything, and keeping the second and possibly third set under lock and key, and not telling anyone about its existence. Then, if something does go walkabout, and you have to get the 2nd set of something out, you have time to order a replacement for the first, and will still have a backup if the 2nd set goes walkabout before it arrives.

Maybe it is just me, but a lot of the time when I hear people say "power screwdriver", they mean "cordless 18V drill in screwdriver mode" (often in the hands of someone not old enough to drink alcohol), which is a recipe for screw tightening disaster, and I certainly understand the resulting reluctance. We have a bunch of Milwaukee 6547-22's around here, they're a 2.4V two speed screwdriver with a torque clutch that's designed to be an assembly line worker's or electrician's screwdriver. While it is possible to generate damaging forces with this unit, generally the torque on high speed is fairly low, and it takes just a little training to show someone how to use a medium clutch setting and high speed (and a flick of the wrist at the end for just a little extra tightness if needed) as a way to handle most data center screw tasks. Once you replace all the drives in a 24-drive chassis (96 screws) you come to appreciate the perfect screw job every time. Once you multiply that times 9 servers per rack times however many racks, you'll never want to do it any other way. We combine the Milwaukee with a Senco Phillips #2 bit. The 9 inch long bit seems awkward until you've used it a few hours, when you suddenly figure out that you can actually SEE what you're working on and/or reach into ridiculously tight spots. Lightly magnetizing the tip creates an even more useful tool. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.

I can see the need for speed & efficiency when actually building a data centre of the scope Google builds with thousands of servers, racks everywhere etc. During the assembly stage, you probably want expensive power screwdrivers to not only save time, but also achieve the right torque/tightness. And you would need many of them since you'd have many people assembling racks and mounting equipment on them. However, in a day-to-day operation at an established data centre, do you really need a power screwdriver ? You need to worry about mounting it on a wall near a plug so it is always available/charged. However, having a powered drill somwehere in the building is, of course, a good thing.

I have a power screwdriver I use for both in and out. Otoh for screwing things in I always have it on the lowest torque-clutch setting.

You need to consider cases where there is an actual power failure. yeah, a real one with dark centre, UPS and mains down, room is silemt except for a few alarms here and there, and you are scrambling to find/fix problem. what will you need ? (obvious things like flashlights, multimetre, screwdrivers, pliers, wire cutters). I would also do a visual inventory of the hardware and all the screws you can find to ensure you have screwdrivers or allen keys for them, adjustable wrenches etc. You may also consider cases where the airconditioning unit is leaking water. Do you have some kit to wrap a leaking pipe to at least temporarily stop the leak ? So you have a shop vac to suck up water on floor or underfloor ? Often, maintenance manuals for equipment will have a list of tools needed. Then you need to consider emergency suplies. 10 gauge wiring to create a glorified extension cord to power some critical equipment. Obviouslty, as somone else mentioned spare ethernet cabling to also provide long patch cord to some switch that is still working. This also depends if this is a commercial data centre or a corporate one. In a corporate one, you need to identify your business critical equipment and run various failure scenarios to see what you need to keep the business critical systems up. While this goes beyond a set of tools, creating that list should implicitly also cause you to create a list of tools you would need in an emergency to get your business critical boxes back up.
There's one thing which no one has really mentioned, but it's "bitten" me a few times personally. * Torx screwdriver set. You'll never know when you run into an "aged" server which has scsi disk's and it requires a torx screwdriver to take out the screws without threading it.

d'oh. I tried to find relevant previous threads. I really did. Obviously not hard enough. Thanks!
I keep a couple of RJ45 line joiners, a short crossover cable (for dealing with older gear that doesn't auto-MDIX, can be extended with a longer eth cable and one of the line joiners) and when I was dealing with fibre a lot, appropriate line joiners for the interfaces I used (SC-SC, LC-LC, ST-ST) or short lengths of patch leads with appropriate adaptors. In an emergency I want to know that I have the ends I need and the length I need to get stuff connected, even if I have to schedule a routine change later on to swap in the 'right' type of cable. I also found that the Nortel gear I used to work with, had the right serial cable pinouts that I could use a pair of Cisco OEM console cables, joined with an RJ45 line joiner, as a serial console cable, so I always carried at least two of those. A Media Converter was also useful in my fibre days, in case I didn't have any spare SFP's or appropriate fibre modules. I also carried an IEC-to-conventional-mains ("3 pin" but it's country specific obviously) to allow me to run up said media converter when the only power outlets were of the IEC sort (where the power brick was inevitably one for 'conventional' mains outlets. I used to keep CDR's (where USB wasn't always permitted) with useful software, including packet capture software, tftp server software and some other basic apps, including plenty of Portable apps. OpenOffice Portable saved me in terms of an ability to get access to documentation (in .xls, typically) when working on the console of a server without Excel installed. But yeah plenty of good sources and I do feel this should indeed be wikified somewhere. I assume http://www.as30950.net/index.php/Main_Page is a useful location?
