An anonymous reader writes "We completed our new 4,000 sq. ft. data center (Tier II/III, according to The Uptime Institute) and just recently moved our core systems from our old data center to the new. We've been up and running for several months now and I'm preparing to close out the project. The last piece is to purchase some accessories and tools for the new location. The short list so far consists of a Server Lift, a few extra floor tile pullers, flashlights and a crash cart. We'll also add to the tools in the toolbox located in one of the auxiliary rooms — these things seem to have legs! What are we missing? Where can we find crash carts set up more for a data center environment (beyond the utility cart with and LCD, keyboard, and mouse strapped to it)?"

Lots of cheap plastic tarps that are stored out of the way but that you can deploy quickly in the event of a water event.
I know, you think you'll never use them, but if you do (storm leaks, broken pipe above, etc...), they'll be the most valuable tools you could have spent $100 acquiring a whole bunch of.
You just haven't lived if you haven't empirically tested (even accidently) how long it takes for power circuits under six inches of water to blow, or how those drop ceiling flourescent tube lights look when they're full of water and still going, or how long servers and switches stay up with water pouring down the racks into them....

1. A list of what UPS' take what batteries, and contact with a vendor that can get them to you ground in one day without having to pay overnight shipping. This is priceless. Trust me. If you have a full-center battery backup this actually makes it even more important, not less.
2. A *REPUTABLE* generator service person, and a service agreement. I never realized how hard it was to find someone that was reliable, and that when they say "24-hour service" it means that someone actually answers the phone, and responds withing an hour, or heck, even a day.
3. Lots and lots of screws, cage nuts, and cage nut removal tools. All of the prior have a habit of up and walking off. Have plenty on hand.
4. Hideaway bed. I'm not joking. Have a place where a tech can crash after a 2 am service call. Better than driving exhausted.
5. AdderLinkIP, phone line installed to core rack, and Modem. Hook the AdderLinkIP to your KVMs, and code in all hosts. Now you can get console remotely on any box, PLUS if your internet connection should go down, someone can dial into the AdderLink, and be able to troubleshoot the net connection from the inside without having to drive. Priceless.
6. If there is not a break area nearby with a fridge, get a mini fridge. Stock the fridge with caffeine. Make this a habit that the company provides. Caffeine without having to leave to get it is priceless during a crash too.
7. Anything else you can think of to make your network engineers LESS repulsed at the idea of having to be there. After a while being "the guy(s)" to go to when things go down has it's novelty wear off. If it's within an office, an arcade cabinet, darts, an XBox, ANYTHING....ask them what they enjoy doing in their off time. Heck, alcohol in small quantity is even done in our office (we have a micro-brewery across the street - I have 2 growlers in the office for those long weekend projects).
By saying you're Tier II/III, it leads me to believe you don't have to present as much of an image (hyper-clean room environment with lots and lots of racks, and nothing else), so do what makes you feel comfortable there. You'll be spending more time than you'd like there soon.

Nice crash cart (Score:4, Informative)
At my current and my past company, they work real well. I looked high and low for a good crash cart and nothing seemed to come close to these. Maybe I was just searching the wrong terms(and apparently my vendors were too). They are a bit pricey though, ~$1500 or so to start. I have a Styleview LCD cart at my current job, and had a LCD cart and a laptop cart at my last place (servers were co-located in a ~900 sq foot cage, 8 feet between rows, so plenty of space for the carts).
I also bought a KVM over IP/CAT5 solution from raritan(http://www.raritan.com/ [raritan.com]), which worked out real well for those situations where a serial console wasn't enough(unless you have fancy out of band management, some do, some don't). I setup tables in the front of the cage, hooked up a couple of the raritan hardware clients. Typically ran one CAT5 cable w/KVM hookup to each rack, so it could be plugged into any system fairly easily. Range of 1000 feet. This was pretty pricey too, with the adapters and all it was about $25k. Though in the grand scheme of things it was cheap at the time. I had cyclades terminal servers in every rack, with serial consoles on all the servers and network gear.
Also I hooked up a temperature sensor board, from Sensatronics(http://www.sensatronics.com/ [sensatronics.com]) I think. I think it was a 16 port board, and I bought all 300 foot cables for all of the sensors, and cut them to length. This ended up being about $5k I think(I went way overkill on the cable lengths).
At my current company we use servertech(http://www.servertech.com/ [servertech.com]) PDUs, their higher end models come with optional temperature/humidity sensors so we use those instead of the senatronics.
Despite it being a co-location, we had 500kW of power going into that cage(standard setup was ~12kW/rack), if the data center had followed their own procedures(AT&T enterprise network services), we would of had to have about a 5,500 sq foot cage, comparable to your data center

I have a small site with about 8 computers and 3 servers and there is wireless shooting to 3 other buildings with about 4-6 computer each in them about 50 feet apart. I was over ridden in our battery backup system in favor of $50 ups purchased for each computer separately at office max. I'm thinking OK, they are getting a generator and I told them to make sure it had a line conditioner and was certified to work with sensitive computer equipment. besides, when it was just the one building, the UPS worked just fine.
They ignored that and one the test, after all the batteries went down, the computer just quit because the UPS software conflicted with a proprietary app the chose to use. I was called in by the guy who installed the generator and was told that about 20 of the UPS were bad. I though ok, they have been there for a couple of years in some cases and brought down some replacements. I swapped them out, they tested it again and before I got back to the shop I got a call saying more of them were bad. All the local sources were out and the electrician told me he had better backups so I told him to get them. after swapping them out I asked to make sure that they had a clean electrical line coming off the generator and they assured me there was.
Two weeks later, a car hits a telephone pole, the electric was out for more then 10 hours. All the UPS units went out, None of the computers would work. I tested the electrical line and it was jumping between 70 and 150 volts at about 40 hertz. All the ups shut down and wouldn't take power, they decided to plug the computers directly into the wall outlets and took two main boards out, three power supplies and the rest of the computers just wouldn't power up.
The data base on one of the applications got corrupted beyond repair and they had to recreate a weeks worth of entries because the drive got corrupted on the backup server too when the main board went out and no one had made the external backup in over 5 days. The phone system was borked, a 64 inch plasma TV in the lobby was gone, and various other things needed replaced because they acted weird from then on out. The line conditioners should have been about $90 per outlet or about $2000 for one capable of regulating all the power coming from the generator. In the end, it costs around $10,000 in replacements, labor and everything plus they ended up buying a new generator and this time getting a power control system that was certified for sensitive electronics.
Bad power will cause so many problems it isn't funny. Most people don't even know that a generator can be out of whack on output. Not all of them are created alike. Small things like how fast they can adjust to the load pulling from them and how stable the current is isn't a given. You have to make sure it is there or end up with broken electronic every time the power goes out and it kicks on.

I've seen several good suggestions already with specific suggestions on tools or parts. Start with those. My suggestion is quite simple, actually: Why GUESS what you need, when you can find out for sure?
Tear down one ENTIRE rack. (Or several, if they have any variations.)
Now, look at this big pile of parts in front of you and imagine what you would do WHEN *ANY* one of them breaks.
Get several spares for each of those parts and put into the cart.
Whatever tools you needed for disassembly, put into a crash cart.
Then make another, identical cart. When the brown stuff hits the spinnie thingie, and multiple systems are down, the last thing you want to be doing is fighting over tools. Get spares of EVERYTHING so at least TWO people can work on things at the same time! You'll thank me when there's two of you trying to work on both sides of a rack.
NOTE: Be sure to inventory what you put into each cart! Tools have a way of growing legs and you want to be able to check and make sure that you STILL have ALL the tools.
And please consider getting a big-ass UPS for your cart (At least 1KVA). If your power is wonky, you want to be sure your cart's equipment (laptop, hub, switch, router, etc.) won't be flaking out as the power comes and goes. Even with the power out, you can plug one server into the UPS and restore/repair it while the power is still out. While you're at it, also get some LONG extension cords (100-foot) made of AT LEAST 12-gauge wire. Plug the UPS into the extension cord.
Think you're all set? Now, using ONLY the tools on ONE crash cart, put the rack back together. With the power out. (i.e. no mains)
When you have done this, not only will you be CERTAIN that you have all the tools you needed to [re]assemble everything, you'll actually have done so and will have run into (hopefully) most of the problems that you could encounter.
That's it off the top of my head. Best of luck to you! P.S. One last thing: MANY rolls of Duct Tape! <grin>
