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.

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.

SNMP Management Module LEDs

The SNMP Management Module features several LEDs. The LED functions are:
