Power Supply Removal and Replacement
Model 5802V power supplies are hot-pluggable: you can remove or install one of
the power supplies while the switch is operating without disrupting service. The
power supplies are also interchangeable; that is, the left and right power supplies
are the same unit.
When removing or replacing a power supply, consider the following:
The left and right power supplies are interchangeable. However, you must
orient the power supply so that the AC receptacle is on the right.
Both power supplies must have the same air flow direction. The part number
label on the power supply indicates the air flow direction.
When removing or replacing a power supply on an operating switch, be sure
that the Heartbeat LED is blinking once per second (normal operation), so
that the switch can correctly report the power supply status.
To remove a power supply, unplug the power supply, and then loosen the two
knurled fasteners with a cross-head screw driver, as shown in Figure5-1. Grasp
the power supply handle, and then pull firmly to disengage the modular connector.
Slide the power supply out of its bay.

CAUTION!
Both power supplies must have the same air flow direction to prevent the
switch from overheating.
To avoid overheating, do not operate the switch with one power supply
any longer than necessary.
