LED Indications and the Safety Interlock Mechanism
On the Cisco 7513 and Cisco 7576 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.

LED Indications
The power supply LEDs include the AC OK LED, the FAN OK LED, and the OUTPUT FAIL LED.
(See Figure 3.) 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.

Power Supply LEDs
The OUTPUT FAIL LED lights for either of the following reasons:
•
Power supply DC-output failure, which might be caused by an overload by the system or an
actual failure in the AC-input power
actual failure in the AC-input power
•
Power shutdown that is initiated by the power supply because it detected an out-of-tolerance
voltage condition in the power supply
