SNMP Write Lock

There is an SNMP Write Lock switch located above the SNMP module slot on the front of the iMediaChassis/6. 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 how to configure and operate. If an SNMP Management Module is installed, refer to the LED panel below for indicators of Link, Temperature, Power Supply modules and other functions.
