Fan Failure
CAUTION If a fan fails to operate it should be replaced immediately. The Kayak HD frame
shuts down when its internal temperature reaches 75-degrees C.
If there is a fan failure, the network panel displays an exclamation mark ( ! ).
The fan board is hot pluggable (as are the power supplies and M/E boards).
CAUTION Do not attempt to run the Kayak HD system without functioning fans. This
can cause sever damage to circuit boards.
