If your HPE 5400R zl2 Switch is configured with redundant power supplies, you will not suffer any loss of traffic or performance if a power supply fails. Replace the failed component as soon as possible. One of the Internal Power LEDs on the management module will blink simultaneously with the switch Fault LED indicating which power supply failed.
Although these procedures show the 6-slot chassis, the procedures are the same for the 12-slot chassis.
To replace an AC power supply
Ensure the AC power supply is not plugged into an AC power source on the failed power supply.
Using either a flat-bladed or Torx T-10 screwdriver loosen the retaining screws and remove the failed power supply.
Insert the replacement power supply into the opening. Slide it all the way in until it connects to the switch. The power supply face plate will be flush with the back face of the switch.
Tighten the four retaining screws that hold it in place. Be careful not to overtighten the screws.
For more details, see the HPE Switch zl2 Internal Power Supply Installation Guide.
