4.3.2 SNMP Write Lock
The SNMP Write Lock switch is located on the
back of the 3-Slot 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
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.
