The SANbox 5202/5602 power supplies are hot pluggable. This means 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 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 
the Heartbeat LED is showing the normal 1 blink per second. This allows the 
switch to correctly report power supply status.

To remove a power supply, unplug the power supply and loosen the two knurled 
fasteners with a cross-head screw driver as shown in 

. Grasp the power 

supply handle and pull firmly to disengage the modular connector. Slide the power 
supply out of its bay.

„ 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.
