redundancy, a failed fan tray should be replaced as soon as possible. The Fan LED, Global Status LED and
Fan tray LED will FLASH amber, indicating a fan tray has failed.
The Aruba 9300-32D switch is not compatible with fan trays from other Aruba hardware platforms.
n
After removing a fan tray, wait at least five seconds before inserting a replacement fan tray in the same slot.
n
Replace only one fan tray at a time. Removing more than one fan tray at a time compromises system cooling,
n
risks damage to the hardware, and can cause the switch to shut down abruptly.
If there are less than six fan trays installed, a two minute count down timer is triggered. If six fan trays are not
n
present before the countdown expires, the switch will automatically power down and reboot. For this reason, it
is not recommended to remove a failed fan tray, until you have the replacement fan tray prepared.
Ensure that a replacement fan tray has the same airflow direction as other fan trays installed in the switch.
To replace a fan tray:
1. Identify the fan tray by its status LED. The failed fan tray LED will be FLASHING amber.
2. Remove the new fan tray from its packaging.
3. Grasping the handle of the failed fan tray, use the Release Latch to release the locking mechanism
and pull the fan tray straight out to remove it from its slot.
4. Insert the new fan tray fully into the slot so that its face plate is flush with the back face of the switch
and the latch clicks. If the switch is connected to an AC power source, the fan tray should immediately
start running.
