Status LED

The Status LED displays a steady green glow to indicate that power is being provided to the EMM and that the EMM is working properly. This LED blinks when an error occurs during operation or if an error is found when diagnostics are performed during a reboot. Refer to Chapter 4, Troubleshooting, for a description of the error codes.

Master Mgt Module LED

The Master Mgt Module LED displays a steady green glow if this EMM is the master management module in the concentrator. It also displays a green glow while a mastership election is in progress and during initial installation. The LED is off when the EMM is a slave.
