Fan Module Overview
The fan module provides cooling for the internal components. The fan drawer is a field-
replaceable unit containing five fans, and is installed at the right rear of the SCE 1000 platform.
When a fan malfunctions, the fan module should be replaced as promptly as possible. Although it
is possible for the unit to function for some time with one non-functioning fan, this is not optimal
or recommended.
