Troubleshooting Startup Problems
This section describes how to troubleshoot startup problems by monitoring the Interface Status LEDs and the Module Status LED on the RMON MultiProbe Module faceplate.
When you first install the RMON MultiProbe Module in the hub, the module runs the following diagnostics:
❑SRAM Data Bus
❑SRAM Address Bus
The Interface Status LEDs display a pattern during the execution of each diagnostic test. The patterns correspond to the test as indicated in Table
Table 4-1. Diagnostic Tests and Interface Status LEDs
Diagnostic | Interface 1 | Interface 2 | Interface 3 | |
Status LED | Status LED | Status LED | ||
| ||||
|
|
|
| |
SRAM Data Bus | On | Off | Off | |
|
|
|
| |
SRAM Address Bus | Off | On | Off | |
|
|
|
|
If the SRAM Data Bus or SRAM Address Bus diagnostics fail, the pattern of the failed diagnostic remains on the Interface Status LEDs. If this occurs, contact the 3Com Customer Service Center for corrective action.
