Dear all,

I'm having a 2.2KV APC UPS, and i'm connecting my Gentoo email server on it,
so what is the proper way to configure my server to auto shutdown, when the
Main power off.

Thanking you,

Suranga

emerge apcupsd

It works beautifully. :-)  Communication between server and UPS works with serial and USB. I
purchased the additional SNMP card with mine and it works also.

To have a stable system, you will need to:
1) alter your bios so that your server will automatically start up on power restore.
2) Adjust apcupsd.conf to match your server(s) power down requirements.
3) Follow the apcupsd power failure test procedure to insure your server issues a UPS power down
w/delay command during server halt to protect against intermittent power failures.

Ah, it has SNMP (1,2,3 ?) support. That's good news. You may want to
install JFFNMS (waiting on 0.8.3 ebuild bug fix) when it becomes ready
for use. It talks to a wide variety of devices and can store, analyze
and plot parameters. It has a wonderful graphics display capability
(rrdtool). With JFFNMS you can profile parameters (such as your 
batteries and determine when they need replacing) as well as 
many other issues with various pieces of equipment, all in one 
piece of software package. It works with a variety of vendors' 
equipment, like cisco routers not just UPSes, or in case you
have UPSes from vendors other than APC.

JFFNMS is one very cool piece of software. You can status, alarm, 
control and update all sorts of equipment with it (embedded to 
64 bit servers). SNMP support is one of it's strongest features. 
It is also extendable to other legacy or closed forms of equipment,
via a variety of techniques and reverse engineering tricks.
