About the Management (MGMT) LED
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, or HTTP.
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 7GR4270‐12 , 7GR4202‐30, and 7GR4280‐19 DFE modules, you can view the receive and
transmit activity on the RX and TX LEDs. However, only one group of six ports may be viewed at
a time on the 7GR4280‐19.
To view the receive and transmit activity on a group of 7GR4280‐19 segments, press the GROUP
SELECT button (see Figure
through 3). Each time the GROUP SELECT button is pressed for less than one second, 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.
