observe all static precautions when replacing components.
If a power supply must be removed and then reinstalled, wait at least 5 seconds before

reinstallation. Otherwise, damage to the switch may occur. The power supply needs this time to
discharge any retained power.

Replacing a Power Supply

Never insert or remove a power supply while the power cord is connected. Verify that cord has been
disconnected from the power supply before installation or removal.
If the Aruba 9300-32D switch is configured with a redundant power supply, the switch will not suffer any
loss of traffic or performance if a power supply fails. To maintain system redundancy, a failed power supply
should be replaced as soon as possible. The LED on PSU1 or PSU2 will be on or flashing amber if faulted.
Two power supplies are available for use with the switch:
Aruba Front-to-back airflow power supply
n
Aruba Back-to-front airflow power supply
n
Air flow direction must be the same for both the power supply and the fans installed in the switch.
