Holding the DMM by the faceplate, slide it into the slot in the 8260. Like all 8260 modules it can be hot plugged.

If the EC-DMM has been installed correctly and is functioning the status LED should come on. The LCD display should show diag then either rdy for the master module or stby for a backup module.

The LCD display and display control button are used to:

Display the current operating state of the module.

Determine the network assignment of ports and 8260 modules in the hub.

Display the version of the EC-DMM microcode.

The LCD display normally shows the module operating state. Each time the display control button is pressed the character display cycles through each of the networks. By using the network display LEDs on the EC-DMM and the 8260 media modules it is possible to see which modules and which ports are assigned to a network.

For example, we have an 8260 24-port port switching module in slot 2, with ports 1, 3, 5 and 7 assigned to Ethernet_1 and a similar module in slot 4 with ports 15, 16, and 17 assigned to Ethernet_5. If the control button is pressed once the LCD display will change from rdy to E1. The Ethernet network status LED for Ethernet_1 on the DMM will turn on. The LEDs for ports 1, 3, 5 and 7 on the 8260
