small LED indicators for Link and Data Activity. For more information on Network
Port configuration, please refer to Section 5.9.
MasterA/BGangSwitch: Allows manual control of A/B switching at up to sixteen
Circuit Modules. Note that the Master A/B Gang Switch can be disabled as
described in Section 5.3.
ALMIndicator: The ALM Indicator will light when Monitor Input Alarm is triggered.
For more information on the Monitor Input Alarm, please refer to Section 7.6.
