9. LED Indicators
The interface contains several different LED indicators, each of which conveys important information about the status of the unit and connected networks. These LEDs and their functions are summarized here.
9.1 Module and Ethernet Indicators
The module and Ethernet indicators are located between the MMI port and the Channel A drive port. Figure 6 indicates the functions of these LEDs.
