B.2.1.1 LED display of the MMB

Besides the Power-LED (green), Alarm-LED (orange), and Location-LED (blue), the
MMB has a Ready-LED (green), which indicates that the MMB is being operated,
and the Active-LED (green), which indicates that the MMB is the Active one of
duplicated MMBs. Since the Ready-LED is synchronized with MMB-Ready on the
operator panel, the MMB status can also be checked from the operator panel.
Also, the MMB has LEDs for a LAN. The Speed LED is placed to the left of the
LAN connector and the Link/Act LED is placed to the right of it.
