CRS-300 1:10 Redundancy Switch
Revision 16
Front Panel Operation
MN/CRS300.IOM
7–10
CONFIG: OPTIONS
Æ ALARM-MASK
If
ALARM-MASK is selected:
ALARM MASK: MODEM-ALARMS
SW-ALARMS AUDIO (ENTER)
Select MODEM-ALARMS, SW-ALARMS, or AUDIO, then press
[ENT]
. The Switch logs and
reacts to both its own faults and modem faults. Either type of faults may be masked using this
submenu. In addition, an audible buzzer can be enabled as an additional indicator.
CONFIG: OPTIONS
Æ ALARM-MASK Æ MODEM-ALARMS
If
MODEM-ALARMS is selected:
MODEM ALARM MASK: NONE
TX RX TX+RX (ENTER)
Select NONE, TX, RX, or TX+RX, then press
[ENT]
.
The User may 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: 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 active
modems only.
CONFIG: OPTIONS
Æ ALARM-MASK Æ SW-ALARMS
If
SW-ALARMS is selected:
SWITCH ALARM MASK: NONE
ËPSU-A PSU-BÌ (ENTER)
Select ËPSU-A or PSU-BÌ, then press
[ENT]
.
The User may select which, if either, of the plug-in power supply units needs to masked. 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.
CONFIG: OPTIONS
Æ ALARM-MASK Æ AUDIO
If
AUDIO is selected:
AUDIO MASK: NONE SW-ALMS
MODEM-ALMS BOTH (ENTER)
Select NONE, SW-ALMS, MODEM-ALMS, or BOTH, then press
[ENT]
.
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.
