Do not force a fan-tray assembly into place. Doing so can damage either the connectors on the fan tray
or the connectors on the back panel of the shelf, or both.
Caution
Error messages appear on the TNCS/TNCS-O card, the fan-tray LED, and in the Cisco Transport Controller
(CTC) when the fan-tray assembly is removed from the shelf or when a fan is not working.
