If you see the above output, it is a good sign that apcupsd is working. Assuming that the output looks

reasonable, check the following variables:

LINEV

This is the line voltage and it should be a value that is appropriate for your equipment. In the USA, it

is typically about 120 Volts while in Europe, it is about 220 Volts.

BATTV

Unless you have additional battery packs, this should be near 24 Volts plus or minus 5 Volts.

STATUS

This is the status of the UPS and it should normally be ONLINE.

A very disturbing tendance is for some of the newer (Mar 2004) RS and ES UPSes to have no Voltage

information. This is an annoying bug, but not serious. On the other hand, some of those UPSes now have

no battery charge information BCHARGE. If BCHARGE is zero in your listing and you are running a Smart or

a USB UPS, then you will have to set the BATTERYLEVEL directive in your apcupsd.conf file to -1.

If you see a message to the effect of:

APCACCESS FATAL ERROR in apcaccess.c at line 336

tcp_open: cannot connect to server localhost on port 3551.

It means that you have probably not enabled the Network Information Server in your configuration file for

apcaccess to work. This is done by setting NETSERVER and NISPORT in your apcupsd.conf file as

shown above.

Communications Test

At this point, you should ensure that apcupsd is handling the connection to the UPS correctly. This test

assumes you have a UPS that speaks apcsmart protocol, over either USB or a serial port. If you have an

old-style voltage-signaling UPS, please skip to the next section (Simulated Power Fail Test).

When apcupsd detects a problem, it generates an EVENT, which consists of sending a message to the

system log then invoking the apccontrol script (normally in /etc/acpupsd/apccontrol) to handle the

event.

In order to create an event, remove the serial port plug from the back of your computer or from the back of

the UPS. Within 6 seconds, apcupsd should detect the lack of serial port communications and broadcast a

wall message indicating that the serial port communications was lost:

Warning communications lost with UPS lost.

At the same time, it sends the same message to the system log and to the temporary EVENTS file

(/etc/apcupsd/apcupsd.events).
