The MGMT LED (shown in Figure
Module to control the management functions for all DFE modules in the chassis. The Management
Module handles all IP requests to the chassis IP address, such as PING, Telnet, SNMP, and HTTP.
The Management Module also handles the CLI configuration sessions by means of the console
port. So, when you plug into a DFE module COM port to configure a module in the chassis, it is
handled by the Management Module regardless of the DFE module COM port that you use.
Viewing the Receive and Transmit Activity
On the 7G4202‐72 and 7G4282‐49, you can view the receive and transmit activity on the RX and TX
LEDs. However, only one group of ports may be viewed at a time. On the 7G4282‐49, there are 8
ports per group. On the 7G4202‐72, there are 20 ports per group.
To view the receive and transmit activity on a group of attached segments, press the GROUP
SELECT button (see Figure
Groups 1–5 for the 7G4282‐49). Each time the GROUP SELECT button is pressed, the GROUP LED
lights up in sequence, indicating which group is selected. The receive and transmit activity for that
group of segments is then indicated by the RX and TX LEDs for each port.
