Dual Power Management

154 BLACK BOX ® Advanced Console Server

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 syslog-ng.conf file must be changed. See the section Generating Alarms

Configuration for CAS

vi Method

Files to be changed:

/etc/syslog-ng/syslog-ng.conf

Browser Method

Follow the steps described in the section “Generating Alarms.”

Note: This section applies only to the dual power supply model of the BLACK

BOX ® Advanced Console Server.
