Replacing the chassis cooling module

It is not necessary to remove power to replace the cooling module. However, the
cooling module must be replaced as quickly as possible to avoid overheating other
modules in the unit. Unpack the replacement cooling module unpacked so that it is
ready for installation before removing the cooling module being replaced.
Warning
not completely remove the cooling module until the internal fan has stopped
moving, as detailed in step 3 and step 4 below.
