Fan Module
The 4000E fan module is installed vertically to the right of the interface
module slots. It comes pre-installed and should not be removed unless it is
being replaced. Fan functionality is indicated by the FAN LED on your
management module (all models): No illumination or solid green illumination
indicates all fans are currently functioning, solid amber illumination indicates
at least one of the four fans is no longer functioning.
CAUTION:
Do not operate the 4000E without a fan module or with a fan module that
is not functioning properly.
