UPS monitoring for Linux

Unfortunately, no responses on this. So I just tested it out myself. Here's my results:

1. This will work properly. You must use a serial connection. USB is not going to work.
2. Yes I got it working and am now using it for a couple of installs with no problems. I also tested it out in a lab and shutdown worked perfectly
3. No SNMP monitoring. This is rather unfortunate. The only way to use any SNMP monitoring software like Nagios is to have a network management card installed or use the PowerChute
4. I really don't see a whole lot of reasons to use a network management card if you're only working with one server. I could be missing something though.

Another note: Make sure you set Hyper V to shutdown DCs on shutdown instead of suspend them. Otherwise, your clocks are messed up for a few minutes following a power restore. Machines other than DCs should not have this problem as they should be syncing their time from the Hyper V server.

It is probably not place at the bottom accidentally. Typically the UPS is the heaviest thing in the rack. Meaning it is easiest to install it at the bottom where you don't have to lift it up.

One might argue, that putting the heaviest things at the bottom should also make it more stable. If it was top-heavy, and not bolted down, then there is the remote possibility a strong earthquake would tip your rack.

Good tips and tricks for managing the mess of wires behind the rack.

Lots of cable management

Some devices I have have cable arms

IMHO the cable arms that come with the 1U servers mostly cause more harm then good. Disconnecting, and completely removing the 1U boxes usually seems easier to me. But I really like them on the 6U SAN. The drives must be replaced from the top, completely removing that would be a PITA.
