Upgrading the 1200-Watt, AC-Input Power Supplies in the Cisco 7513
OL-6324-01
Product Overview

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
