Cooling Fan Module
The cooling system consists of two high-performance (80-CFM)
cooling fans enclosed in a single fan module (see
). The
fan module fits into the open bay at the rear of the storage
subsystem and is hot-swappable.

If the storage subsystem temperature exceeds the established
threshold of 60° C (140° F), the fan status LED on the front bezel
begins to flash amber. (The SAF-TE processor monitors the
temperature and reports when this condition occurs.)
