Troubleshooting
This chapter provides information concerning the following:
• Using LANVIEW (page 4-1)
• Troubleshooting Checklist (page 4-7)
• Overview of DFE-Gold Module Shutdown Procedure (Special Instructions) (page 4-9)
• Recommended Shutdown Procedure Using OFFLINE/RESET Switch (page 4-10)
• Last Resort Shutdown Procedure Using OFFLINE/RESET Switch (page 4-10)
Unless otherwise noted, the following information applies to all DFE-Gold 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-Gold 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 through the console port. So, when you plug into a
DFE-Gold module COM port to configure a DFE-Gold module in the chassis, it is handled
by the Management Module regardless of the DFE-Gold module COM port that you use.
