Power Supply Diagnostics
A power supply has a Fault LED (Amber) and a Status LED (Green), as shown in
Figure 4-7. Model 5802V power supplies are replaceable. Under normal operating
conditions, the Power Supply Status LED is lit, and the Power Supply Fault LED is
not lit.
Figure 4-7. Model 5802V Power Supply LEDs
Consider the following indications:
The Power Supply Fault LED is lit, indicating that the power supply is failing
or has failed.
For dual-power supply model 5802V switches, replace the power
supply with another power supply that has the same air flow direction.
Air flow direction is indicated on the power supply part number label.
Refer to “Power Supply Removal and Replacement” on page 5-2.
For single-power supply model 5800V switches, shut down the switch
and contact your authorized maintenance provider.
(Model 5802V only) All power supply LEDs are normal, the System Fault
LED is lit, and the Heartbeat LED does not show a blink pattern. This
condition means that the two power supplies have different air flow
directions. Replace the power supply with the incorrect air flow direction with
another power supply having the correct air flow direction. Air flow direction
is marked on the power supply part number label. Refer to “Power Supply
Removal and Replacement” on page 5-2.
