supply status
ON green
The power supply is operating normally.
OFF
The power supply is not providing its 12V
output, unpowered, disabed or in failure
mode.
Load sharing
Load sharing occurs when two power supplies are installed in the switch and turned on. Load sharing
divides the total power load of the switch among both power supplies.
Redundancy
With power redundancy, the Aruba 10000 switch can continue normal operation even when one power
supply fails or is powered off. When two power supplies are installed, if one becomes unavailable (fails, is
powered off or removed) the remaining power supply provides full power for the device.
Even though the switch will run with one power supply removed, for thermal integrity reasons it is highly
recommended to not remove a failed power supply, until the replacement can be installed.
Hot swapping
Hot swapping allows you to replace one failed power supply while the other provides full power. This makes
it unnecessary to shut down the switch during the replacement procedure.
If both power supplies are faulted, missing and/or use misconfigured airflow direction, the system will shut down
for five minutes due to insufficient cooling.
Never insert or remove a power supply while the power cord is connected. Verify that the cord has been
disconnected from the power supply before installation or removal.
Fan trays
The Aruba 10000 switch is equipped with six field-replaceable, hot-swappable fan trays. Each fan tray
features individual fans that pull air through the chassis from Port-to-Power or Power-to-Port.

In the event of missing fan trays, misconfigured airflow direction, and/or faulted fans, the switch will try to
maintain adequate cooling by increasing fan speeds and/or disabling misconfigured devices. If adequate cooling
cannot be maintained, the switch will power off for five minutes before rebooting and assessing cooling
capabilities.
