Appendix A. Troubleshooting
This chapter offers suggestions for detecting and troubleshooting typical fault conditions in the switch and
for verifying Controller Module/CPSW2 module operation.
Troubleshooting Fault Conditions
Table 8 lists possible troubleshooting you can perform using LEDs. The LEDs listed are located on the
front panel of the Controller modules and CPSW2 modules. Depending on your installation you should
check the LEDs:
Ÿ
On the Controller module if you are using the standard CPSW module or the CPSW2 module with
integrated power control disabled (FORCE RCTL jumper set to ON on the CPSW2 module). If you
have two Controller modules installed, you should check the LEDs on the active module.
Ÿ
On the CPSW2 module if you are using the integrated power management functions (FORCE RCTL
jumper set to OFF on the CPSW2 module). If you have two CPSW2 modules installed, you should
check the LEDs on the active module. If you have CPSW2 modules installed, but have disabled power
management, you must check the LEDs on the active Controller module.
If you cannot correct a fault condition using any of the suggestions provided, contact your local service
representative for assistance.

operation.
Blinking Power supply faulty. 1. Verify that the outlet is supplying
power.
2. Verify that the power cord is plugged in
at both ends and that the cord is
appropriate for your country's line
voltage.
3. Verify that the power switch on the
power supply is set to the ON position.
4. Verify that the power supply is fully
seated in the backplane connectors.
5. Verify that the power supply is not
overloaded. Set the power supply
switch to the OFF position, wait a few
moments, then set the power supply
switch to the ON position.
6. Check that the power supply
connectors on the backplane are not
damaged.
7. Replace the power supply if the
suggestions presented above do not
correct the problem (see page 61).
