To set up apcupsd on SME 7.4
Setup DAG repository
yum install --enablerepo=dag --enablerepo=base apcupsd
COPY ORIGINAL CONF
cp apcupsd.conf apcupsd.conf.orig
COPY CGI FILES
cp /var/www/apcupsd/* /home/e-smith/files/ibays/Primary/cgi-bin/
LINK STARTUP SCRIPT
ln -s /etc/rc.d/init.d/e-smith-service /etc/rc7.d/S99apcupsd
SET SERVICE IN SME
config set apcupsd service status enabled
Edit /etc/apcupsd/apcupsd.conf. The conf file has good detail on setup options.
Suggest setting the TIMEOUT to 600 seconds; You shouldn't let UPS batteries run down to 5% (default) as this massively shortens their life. Set TIMEOUT to 10 for testing.
Reboot or /etc/init.d/apcupsd start to start the service.
