Troubleshooting
This chapter provides information concerning the following:
• “Using LANVIEW” (page 4 ‐ 1)
• “Troubleshooting Checklist” (page 4 ‐ 5)
• “Overview of DFE ‐ Gold Module Shutdown Procedure” (page 4 ‐ 7)
• “Recommended Shutdown Procedure Using OFFLINE/RESET Switch” (page 4 ‐ 8)
• “Last Resort Shutdown Procedure Using OFFLINE/RESET Switch” (page 4 ‐ 8)
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 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.
