5.3 Dual Power Management
The ACS comes with two power supplies which it can self-monitor. If
either of them fails, two actions are performed: sounding a buzzer and
generating a syslog message. This automanagement can be disabled (no
actions are taken) or enabled (default), any time by issuing the commands:
# signal_ras buzzer off
# signal_ras buzzer on
To disable the buzzer in boot time, edit the shell script /bin/ex_wdt_led.sh
and remove the keyword “buzzer.” The buzzer won’t sound if there is a
power failure in any power supply. This parameter does not affect the
behavior of the command “signal_ras buzzer on/off.” To make this change
effective even after future reboots, create a line with “/bin/ex_wdt_led.sh”
in /etc/config_files, save and quit that file and run saveconf.
Note:
NOTE:
This section applies only to the dual power supply model of the
ACS.
How to configure
There are no parameters to be configured. However, if you want to
generate alarms in case of a power failure, the
syslog-ng.conf file must be
changed. See the section Generating Alarms.
