Reset Alarm Button
When one power supply module malfunctions, an audible alarm sounds indicating the loss of
the power module. The alarm can be silenced by pressing the Alarm Reset Button, located
next to the power connector on the power supply module. If this occurs, remove and replace
the power supply module immediately. (LEDs on the Management Module and the power
supply module itself also indicate power supply module failures.)

Temperature Gauge
The 20-Slot Rackmount 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.

SNMP Write Lock
There is an SNMP Write Lock switch located below slot #3 on the front of the 20-Slot
Rackmount Chassis. The SNMP Write Lock switch prevents a new management board from
re-configuring the application module settings (e.g., the

re-configuring the application module settings (e.g., the
status of
features such as LinkLoss, FiberAlert, Force mode, etc.)

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.
