Troubleshooting
This chapter provides information concerning the following:
• “Using LANVIEW” on page 4 ‐ 1
• “Troubleshooting Checklist” on page 4 ‐ 5
• “Overview of DFE ‐ Platinum Module Shutdown Procedure” on page 4 ‐ 6
– “Recommended Shutdown Procedure Using OFFLINE/RESET Switch” on
page 4 ‐ 7
– “Last Resort Shutdown Procedure Using OFFLINE/RESET Switch” on 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 ‐ Platinum 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 ‐ 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 7G4202 ‐ 60 and 7G4282 ‐ 41, you can view the receive and transmit activity on the
RX and TX LEDs. However, only one group of ports may be viewed at a time. On the
7G4282 ‐ 41, there are 8 ports per group. On the 7G4202 ‐ 60, there are 20 ports per group.
