Verifying Power Supply Operation
To verify normal operation of an installed power supply or supplies, confirm that a power supply fault is not
indicated by checking the Power Supply LEDs.
There are four Power Supply LEDs, one for each power supply. These LEDs are located on the front
panel of the Controller modules and CPSW2 modules. Depending on your installation you should check
the LEDs on:
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 CPSW 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.
The LEDs are numbered 1 through 4, with 1 indicating the left-most power supply bay, and 4 indicating
the right-most power supply bay.
The LED for each unit installed should be lit. If any of the LEDs blinks or does not light for each installed
power supply when the 8265 is powered up, refer to Appendix A, “Troubleshooting” on page 55.
