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.
