1. If a process is currently in operation, bring it to the safe mode, and
orderly shutdown if it is required.
2. Using an external (user-supplied) switch, disconnect the power
supply in the rack (associated with the CPM to be replaced) from
the source main power.

and if necessary, tag them to identify their functions. Unplug all
communications cables.
4. At the top and bottom of the module, loosen the captured screws
