Front Panel Operation CRS-200 Redundancy Switch
7–6 Rev. 1
7.1.3.6 (CONFIG, OPTS) ALARM MASK
ALARM MASK: MODEM-ALARMS
SW-ALARMS AUDIO (ENTER)
The switch logs and reacts to both modem faults and its own faults. Types of either may
be masked using this sub-menu. In addition, an audible buzzer can be enabled as an
additional indicator.
7.1.3.7 (CONFIG, OPTS, MASK) MODEM ALARMS
MODEM ALARM MASK: NONE
TX RX TX+RX (ENTER)
The user is prompted to mask Transmit or Receive Traffic faults (or both) 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. Note that these selections are global to all the modems. If masking
of individual modem faults is desired, it should be done directly on the modem.
Unmasked modem faults are logged on both active and inactive modems.
7.1.3.8 (CONFIG, OPTS, MASK) SWITCH ALARMS
SWITCH ALARM MASK: NONE
b bPSU-A PSU-B` ` (ENTER)
The user is prompted to select which, if either, of the plug-in power supply units should
be ignored in case any of their voltage outputs are monitored by the switch as being out
of range. Only one of the units can be masked at a time. Normally this would be done if
the user wishes to run with only one supply, or if a bad supply had been removed for
service or replacement.
7.1.3.9 (CONFIG, OPTS, MASK) AUDIO
AUDIO MASK: NONE SW-ALMS
MODEM ALMS BOTH (ENTER)
For all switch or modem alarms that are unmasked, the user may select which alarm types
should force the switch to react with an audible buzzer located behind the front panel. In
addition, a relay closure to ground activates on pin 20 of the System Alarms connector so
that the user may attach other indicators.
