RE: Re: Advice on cheap data cabinets and rackmount switches....
Hey Andy, - mean meaning to drop you a line for quite a while...
Re the 1U UPS's - another point I have discovered is that some don't have
enough load capacity for a PC with lots of drives in it! - I have an APC 1U
UPS that constantly shows an overload condition.. :-(
Actually, I have a few UPS's that I need to sort out... - I have a total of
3 APC 1U jobbies, one of them is this 250VA model here... http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SC250RMI1U
This one I bought brand new and is fine, - but can't run my servers because
of the overload described above...
I also (unintentionally) ended up with 2 of the 450VA models from the same
range: http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SC450RMI1U
which I "won" on Ebay... - inverted commas because one of them
was/is DOA and the seller basically shafted me.. :-(
I didn't actually intend to get 2 from Ebay, - I was bidding in 2 auctions
and I didn't expect to win both, but I did!
I only have 2U of rack space available anyway, so the fact that I have one
DOA isn't really a problem.. what I'd like to do though is to see if I can
get it running and use it instead of the 250 model... - when mains is
applied to it, there is a single audible click from inside, - sounds like a
relay switching. - There is no other sign of life, - no power at the
outlets, and no LED's lit at all... - I'm guessing these things are pretty
simple - some batteries, a control board, and I guess some mains PSU bits..
- what would you suggest I try to see if I can resurrect my dead one? - I
can use parts from the 250 model if they are interchangeable...
Many thanks..
PS, so you have any black rackmount UPS's - either 1U or 2U available?... -
I'd prefer to keep to black if poss, since everything in my rack is
black....
TIA
Paul G.

Hi
RE: UPS
Avoid 1U UPSs for servers, PCs, etc for 2 reasons. They don't have
much runtime as can't have many batteries in such a shallow case,
and secondly they tend to use batteries which are harder to get and
more expensive than the standard ones.
The shallow the UPS (low U number), the longer it tends to be from
from to back. As Jim said think about rack depth.
As you might have guessed I am UPS Man. ;-)
If anyone requires a UPS then send me an email at andy@xxxxxxx
or to andy@xxxxxxx or to the Yahoo address I
use here.
I will also have some Masterswitches soon for sale!
Regards
Andy
