Options→Alarm-Mask
Alarm Mask: Modem-Alarms
Switch-Alarms Audio
The Switch logs and reacts to both its own faults and modem faults. Use this submenu to mask
either type of faults. In addition, an audible buzzer can be enabled as an additional indicator.
Use the
◄ ► arrow keys to select
Modem-Alarms , Switch-Alarms , or Audio . Press ENTER .
C ONFIG: Options→Alarm - Mask→Modem - Alarms
This menu operation is global for all modems in the system. Should you desire to
mask individual modem faults, you should do so directly from that modem’s front
panel. Unmasked modem faults are logged on active modems only.
Modem Alarm Mask:
None Tx Rx Tx+Rx
Use the ◄ ► arrow keys to select
None , Tx, Rx, or Tx+Rx . Press ENTER .
You may select Tx to mask Transmit Traffic Faults, Rx to mask Receive Traffic faults, or Tx+Rx
to mask both Traffic and Receive Faults from being reacted to by the Switch. This not only
prevents the Switch from performing Auto Mode functions when these modem faults are sensed,
but also keeps the faults from being logged by the Switch.

PSU for service or replacement.

closure to ground activates on Pin 20 of the “J1 | System Alarms” DB-25F connector (located on
the CRS-530 System Controller module) so that you may attach other indicators.
