Note

Overview of Fan Trays

The Cisco Nexus 7702 switch has one fan tray with three variable speed fans. The fan tray can be removed
and replaced while the switch is operating without presenting an electrical hazard or damage to the switch.
The switch can operate without the fan tray for up to two minutes. If a fan tray is not installed within that
time, the switch will automatically shutdown.

When one of the three fans in the fan tray fails, the remaining two fans run at a higher speed to compensate
for the failed fan and keep the switch operating.

Note

If one or more fans fail within a fan tray, the Fan Status LED turns red. A fan failure could lead to
temperature alarms if not corrected immediately.

Caution

The fan status is continuously monitored by the software. In case of a fan failure, the following actions occur:

•

System messages are displayed.

•

Call Home alerts are sent (if configured). For more information, refer

Associating an Alert Group with

a Destination Profile

.

•

SNMP notifications are sent (if configured). For more information, refer
