About the Management (MGMT) LED
The MGMT LED (shown in
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, HTTP, etc.
The Management Module also handles the CLI configuration sessions via the console port. So,
when you plug into a DFE module COM port to configure a DFE 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 7H4284-49 DFE DFE module, you can view the receive and transmit activity on the RX
and TX LEDs. However, only one group of 12 ports may be viewed at a time on the 7H4284-49.
To view the receive and transmit activity on a group of segments, press the GROUP SELECT
button (see Figure 4-1) to step to the group of interest (Groups 1 through 4). 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.
