Removing and Replacing Fan Trays
In the event of a fan tray failure, signified by an amber LED, an SNMP trap, or major alarm event, the
entire fan tray must be replaced. If one or more fans within a fan tray fail, the system generates a minor
alarm and an SNMP trap.
The fan trays are hot-swappable. To remove or replace the fan tray, you must have access to the rear of
the chassis and be able to pull the fan tray completely out of the slot (at least 20 inches).
