A fault detector monitors the status of each redundant power supply. When a fault is detected it will
trigger a system alarm. When Meridian II is configured with Dual Power Supplies, an alarm will
show if the primary or secondary supply does not have power connected.
NOTE: In the 1U chassis a dual power supply will occupy option slots four and five. In the 2U chas-
sis a dual power supply will occupy slots six and seven.
Masking Dual Power Supply Fault Alarms
You can mask the Primary and Secondary Faults to prevent them from causing a system alarm.
Masking a fault will prevent it from causing the Alarm LED and Alarm Output (if any) from going
active. Masking a fault will NOT prevent it from showing on the front-panel System Faults display
or in the
gpsstat
command.
To mask the fault, traverse to the Faults Menu, then select PwrFltMask. Or, you can use the console
commands
pwrfltmask
and
setpwrfltmask
. Parameters are either Masked or Enabled. Setting
this command to Masked will prevent a power supply fault from creating an alarm condition. The
factory default setting is Enabled.
