Cisco Nexus 9504 - Displaying the Status for the Fan Trays

When replacing a failed fan tray in a running system, be sure to replace the fan tray promptly.
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.
Tip
The software is continuously monitoring the fan status. In a fan failure, the following actions occur:
• System messages are displayed.
• Call Home alerts are sent (if configured).
• SNMP notifications are sent (if configured).
To display the fan module statuses, see Displaying the Status for the Fan Trays, on page 70.
The fan trays fill slots FAN 1, FAN 2, and FAN 3 in the chassis.

to be sure that there is a fabric module that is installed behind the fan tray.
