immediately. (LEDs on the Management Module and the power supply itself also
indicate power supply failures.) After stopping the alarm, remove the power
supply and replace the power supply module.
Last Gasp Alarm
The 6-Slot Rackmount/Desktop Chassis includes the Last Gasp trap feature,
“Remote Chassis Down,” which sends a Trap when the following occurs:
• Both power supply modules malfunction
• Both power supply modules are powered down
• When the AC line fails
Temperature Gauge
The 6-Slot Rackmount/Desktop Chassis includes a temperature monitoring
gauge with a heat sensor on the backplane of the chassis. Users define a
threshold for chassis temperature via SNMP. If the chassis’ temperature rises
above the specified level, the SNMP agent sends a trap (configured in iView²) to
the administrator. There is also an LED indicator on the SNMP Management
Module for chassis temperature.
4.2.2 SNMP Write Lock
There is an SNMP Write Lock switch located above
the SNMP module slot on the front of the 6-Slot
Rackmount/Desktop Chassis. The SNMP Write
Lock switch prevents a new management board
from re-configuring the application module settings
(e.g., the status of features such as LinkLoss, FiberAlert, Force mode, etc.) made
via SNMP on any previous Management Modules.
NOTE
Leave this switch in the NORMAL position during day-to-day operation; the LOCKED
position should only be used when changing the SNMP management board.
The SNMP Management Module can be removed and replaced as necessary.
Refer to the SNMP Management Module manual for complete instructions about
configuration and operation. If an SNMP Management Module is installed, refer
to the LED panel below for indicators of Link, Temperature, Power Supply
modules, and other functions.
