Dual Power Management
The BLACK BOX
®
Advanced Console Server comes with two power supplies which it can
self-monitor. If either of them fails, two actions are performed: sounding a buzzer and generat-
ing 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.
Parameters Involved and Passed Values
There are no parameters to be configured. However, if you want to generate alarms in case of
a power failure, the s
yslog-ng.conf
file must be changed. See the section
