[cobalt-developers] RaQ3 UPS Solutions ?

[Michael Dierker <mdierker@xxxxxxxxxxx>]

Hi,

   I'm the new owner of 2 RaQ3's. I want to connect them to a UPS, and 
have them power down when the power goes off. The RaQ3's comes with a 
separate serial port for UPS use and UPS control software. The 
documentation for the UPS software is virtually non-existent with respect 
to specific UPS models supported, and how to configure them. I have an APC 
Network Powercell that I want to use with the APC grey (dumb) cable. After 
looking through the source, I've come the following conclusions:

1. The software installed on the RaQ3 is based upon the 0.41.2 
Smartupstools release, modified for the RaQ3 with work with the Raq's lcd 
panel. The software includes support for the APC backupspro, and the 
backups. The backups provides support for dumb signalling with the grey cable.

2. It looks as if I can edit the /etc/sysconfig/ups file to change  the ups 
MODEL from smartups to backups. This would give me support for the dumb 
signalling used with the grey cable and PowerCell.

3. Upon a power failure, the Raq will only be power down (by turning off 
the UPS) after the battery has been drained and is low. The problem with 
this strategy, is that if the power is bouncing up and down, then the 
battery will be uncharged on the next outage. I would rather have the Raq's 
shutdown and power-off a specified time after the power failure (say 5 
minutes). There doesn't seem to be a way to do this.

I'm looking for suggestions for configuring the built-in UPS control 
software on the Raq or for other UPS software to use. What is everyone else 
using ???

thanks, mike dierker
