To install the fan tray:
NOTE: The fan tray LED will remain lit when the chassis is ed up and the fan tray is functioning properly.
Removing the Fan Tray
A fan tray failure or a failure of a fan within a fan tray is recognized by a red fan tray LED, a lit RPM
alarm LED, and, if configured, an SNMP trap and alarm event. The failure requires a replacement of the
entire fan tray. While you replace the fan tray, the C-Series system operates safely for approximately two
(2) minutes at an ambient temperature of 77° F (25° C).
To remove the fan tray, you must be able to pull the fan tray completely out of the slot (at least 20 inches)
NOTE: The fan tray must always be installed to ensure proper temperature and airflow control.
CAUTION: Fan blades rotate at high speeds and may cause injury if touched. Adhere to the following
instructions to avoid possible injury.
To remove the fan tray:
Fan Speed
C7008/C300 variable speed fan speed is driven by temperatures measured at the sensor in the fan tray
alone. The sensor is located on the fan tray controller located in the fan tray.

temperature that determines the fan speed.
C7008/C300 fixed speed fan speed is constant and does not change with temperature.
