Power Supply LED Indications

On the Cisco 7513 chassis front panel, the power A and power B LEDs go on when the power supply in the corresponding bay is installed and supplying power to the system. Both the power LEDs should be on in systems with redundant power.

The power supply LEDs include the AC OK LED, the fan OK LED, and the output fail LED. (See Figure 5 for an illustration of the new AC-input power supply’s LEDs.)

The AC OK LED is on when the input power is applied. The fan OK LED is normally on; however, it is off if the power supply fan fails. The output fail LED is normally off, but flashes at power on for a lamp test.

The output fail LED lights for either of the following reasons:

•Power supply DC-output failure, which could be caused by overload by the system or an actual failure in the AC-input power.

•Power shutdown, initiated by the power supply because it detected an out-of-tolerance voltage condition in the power supply
