The UPS is not powered off by apcupsd...

[Aleck Mueller]

My operating system: Kubuntu 8.04
The version of apcupsd I am using: 3.14.2 (15 September 2007) debian
The model and UPS cable I am using: Back-UPS RS 500, USB Cable
Description of the problem:

The relevant part of apcupsd.events during Full Power Down Test (TIMEOUT 0):
Tue Jul 01 15:05:45 ALMT 2008  Power failure.
Tue Jul 01 15:05:51 ALMT 2008  Running on UPS batteries.
Tue Jul 01 15:26:08 ALMT 2008  Reached remaining time percentage limit on
batteries.
Tue Jul 01 15:26:08 ALMT 2008  Initiating system shutdown!
Tue Jul 01 15:26:08 ALMT 2008  User logins prohibited
Tue Jul 01 15:26:14 ALMT 2008  apcupsd exiting, signal 15
Tue Jul 01 15:26:14 ALMT 2008  apcupsd shutdown succeeded

1) While running on UPS battery there were not 4 sound signals from the UPS
every 30 sec as it should be according to the UPS manual.
2) When system shutdown was initiated I expected the current KDE session
should be correctly logged out, but it was suddenly interrupted.
3) The UPS was not powered off by apcupsd. Namely  after shutdown On Battery
(yellow) indicator was lit for about a minute. Then Power on (green) and
Overload (red) indicators blinked alternately several times and went out. I
did not touch power on/off button of the UPS. Afterwards I plugged the power
cord back in and Power on (green) indicator lit up and remained in such state
continuously.

Thank you in advance for any suggestions to fix these problems.

Apcupsd is not involved in this. Ask APC.

This is the job of your operating system. Apcupsd simply issues a shutdown
command (see apccontrol script to find out what command it uses on your
system). Proper logout, etc. is the operating system's responsibility.

Actually, that means it *did* power off. That's exactly the correct
behavior.

Also correct behavior...I'm not sure what you think is wrong?

I expected if the UPS is powered off then I have to push its power on button
when power is back.
Thank you very much for your response.

    This totally defeats the purpose of unattended operations.  When a
UPS is turned off through software (or it ran out of juice), it's not
physically off, it's just in a dormant state, waiting for AC power to be
restored, so it can kick back on, and turn on all the machines hooked on
to it.  That's just normal operations.  Even computers are like that
nowadays...if you physically power them off, they stay off.  However, if
they do a software shutdown because of loss of AC power, they will
restart when power is restored.

Thanks a lot for your explanation.
