Troubleshooting
This chapter provides information concerning the following:
Using LANVIEW Diagnostic LEDs
The DFE module uses 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 modules in the
chassis. The Management Module handles all IP requests to the chassis IP address, such
as, but not limited to, PING, Telnet, SNMP, HTTP. The Management Module also handles
the CLI configuration sessions through 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.
