ControlWave Instruction Manual (CI-ControlWave)
1.
Remove any cables and or the Run/Remote/Local key from their
connectors; make sure you label the cables so you can replace them
later.
2.
Grasp the sides of the bezel assembly and gently pull it off the
chassis.
3.
To replace the bezel, align the bezel’s two snaps (one near the top
and one near the bottom) with the associated holes on the chassis.
(These holes are centered between the PSSM and CPU captured
panel fastener holes.)
4.
Press the bezel in gently until it snaps into place.
5.
Reconnect the cables and reinsert the key, if necessary.
5.2.3 Removing/Replacing the CPU Module
Use this procedure to remove or replace the CPU module.
1.
If the ControlWave is running, place any critical control
processes under manual control.
2.
Shut down the ControlWave by disconnecting the power.
3.
Disconnect any CPU module communication cables. Label or
otherwise identify them so you can easily return them to their
assigned communication ports. .
4.
Remove the bezel. (See
.)
5.
Loosen the two captured panel fasteners that secure the CPU
module to the chassis and carefully slide it out the front of the
chassis. You may need to rock the board back and forth gently to
do this.
6.
To replace a CPU module, the PSSM must already reside in slot
1, but power must be off. Carefully align the CPU module with
the guides for slot 2 and insert the CPU module into the housing.
When the module correctly seats in the backplane, turn the
module’s captured panel fasteners clockwise to secure the CPU
module; this establishes a low resistance path between the CPU
module and chassis ground. Make sure the fasteners are tight,
but don’t over-tighten them.
7.
Replace any communication cables, apply power, and test the
module.
5.2.4 Removing/Replacing the PSSM
Note:
If you have a redundant power supply sequencer module, please
see
Appendix P
.
Use this procedure to remove or replace the PSSM module.
