[Nut-upsuser] Can't make Smart-UPS 1500 shutdown over serial

[Jon Povey]

Hi folks,

Today I installed nut on my Dell Poweredge 1800 server running Ubuntu
8.04 Server, with an APC Smart-UPS 1500 connected to it with the black
APC cable.
I used apt to install nut, upsd -v gives me
"Network UPS Tools upsd 2.2.1-"

I then copied and configured the config files.

Most of the setup seems OK; I get console messages for line power fail /
good, and I can do instant commands to test the front panel and do a
test.failure.start - the UPS switches to battery power and back to line
power after a couple of seconds.

However the commands to shutdown the UPS don't seem to work.
shutdown.stayoff, shutdown.return and load.off all seem to silently do
nothing. Likewise upsdrvctl shutdown:

# upsdrvctl shutdown
Network UPS Tools - UPS driver controller 2.2.1-
Network UPS Tools (version 2.2.1-) - APC Smart protocol driver
        Driver version 1.99.8, command table version 2.0
Initiating UPS shutdown
On line, sending shutdown+return command...
#

(nothing happens on the UPS).

I "faked" a battery low ups shutdown by creating /etc/killpower with the
magic string in and doing a shutdown -h now. According to console output
it thought it was telling the UPS to power off.

Here's the output of upsc:

# upsc ups

ups.temperature: 031.0

Are there some log files I should be looking at, or can I put the driver
in a debug mode somehow? I want to get this working before I rack the
server and forget about it, else if the power comes back at the wrong
time, I appreciate that the server won't!

As the only *nix server in the building that would be embarrasing for my
little *nix fanboy club :)

Thanks in advance,
