Step 6.
Remove the cooling module
from the PSU module. Please refer
to
Section 5.1.
WARNING!

It is recommended that the replacement procedure is completed in less
than five (5) minutes to prevent the subsystem from overheating.
Step 7.
Insert the previously removed cooling module
into the new PSU
module. (See
Section 5.1.
)
Step 8.
Insert the replacement PSU
into the subsystem. Make sure the
ejection handle is at its up-most position so that the saddle
