i have a small telecom rack with four switches or so. would like to add a couple small (1u) rack mount ups. is there a standard location for them? typically i put them at the bottom since they are usually heavy, but in this case the power source is near the ceiling. any reason they can't be mounted above the switches? any type of interference for data connections and patch cables which would be less than a foot or so away to be concerned about?

thanks

Lead-acid batteries above the electronics?
We put them all at the lowest level possible.

We always put them as low as possible. There may be some good reasons out there but I do it because those damn things are heavy and I'm to lazy to pick one up higher than knee level

We only mount DSX's in ours,we use stand alone GNB sets,really big and heavy.If I were to put it in a telco(aux) rack I would go with as close to the bottom.

+1.

And because even though they're sealed batteries, I still don't trust them 100%

Kinda strange to see this question asked here.Guess there are a few of us here that know what that is.

We have seperate battery racks in another room.. for what your doing, put it on the bottom, ( also how we handle "lan closets")

We always put em on the bottom (APC2200's with the NIC) because it keeps the CG lower on the rack and, more importantly, it makes changing the batteries easier.

If you're managing a rack you should know this already.

The last batch came from CDW. Price was ok, plus disposal and shipping of the old ones (hazmat they are) is included.

Down low. Shit man, they're heavy!

Get a longer cord.
Link Posted: 1/4/2006 1:33:05 PM EDT

excellent replies. thanks all around.

i just finished installing. low to the ground turned out to be ok as the power was closer than it had first seemed. with cables and future replacement in mind, it should work well.

Rack stability trumps cord length.

By accident, I found that (at least for APC,) there is a supplimental battery pack that someone else makes. It holds 6 of the same batteries that are in most other apc types. The 3000 apc holds 8, so I have to order 2 of them, but the extra 4 fit in the 1400 apc. Total cost is cheaper than buying 6 new batteries individually.
So when it gets to that time, it might be cheaper to findout the type of battery and what else uses it.

Generally speaking, the first 5 U's from the bottom of the rack is reserved for backup/UPS. In mission critical environment, backup power (battery farms, generators, etc.) are stored in a separate room/building close to the main equipment.

Here is a company that I use.
UPS Batteries

As others have said, watch the CG of the rack. Nothing more fun that to be pulling a piece of gear and see the rack try to follow it.
