Unless otherwise noted, the following information applies to all DFE modules.
Using LANVIEW
The modules use a built‐in visual diagnostic and status monitoring system called LANVIEW. The LANVIEW LEDs (Figure 4‐1) allow quick observation of the network status to aid in diagnosing network problems.
About the Management (MGMT) LED
The MGMT LED (shown in Figure 4‐1) indicates when the module is serving as the Management Module to control the management functions for all DFE‐Platinum 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‐Platinum module COM port to configure a module in the chassis, it is handled by the Management Module regardless of the DFE‐Platinum module COM port that you use.
Viewing the Receive and Transmit Activity
On the 2G4082‐25, 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.
To view the receive and transmit activity on a group of attached segments, press the GROUP SELECT button (see Figure 4‐1) to step to the group of interest (Groups 1 or 2). 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.
