Remove the Cable Management Arm
Before you begin this procedure, refer to Install the Cable Management Arm in SPARC S7-2 Server Installation Guide and identify CMA connectors A, B,
C, and D. You should disconnect the CMA connectors in the reverse order in which
you installed them, that is, disconnect connector D first, then C, then B, and
finally A.
Throughout this procedure, once you disconnect any of the CMA's four
connectors, do not allow the CMA to hang under its own weight.
Note -
References to “left” or “right” in this procedure
assume that you are facing the back of the equipment rack.
| Caution -
To reduce the risk of personal injury, stabilize the rack cabinet and
extend all anti tilt devices before extending the server from the
rack.
|
-
Extend all rack anti tilt devices to prevent the rack from tipping
over.
For instructions for stabilizing the rack, refer to Stabilize the Rack in SPARC S7-2 Server Installation Guide.
-
Extend the server approximately 13 cm (5 inches) out of the front of the
rack, to make it easier to remove the CMA.
-
Remove the cables from the CMA.
-
Disconnect all cables from the rear of the server.
-
If applicable, remove any additional Velcro straps that were
installed to bundle the cables.
-
Unwrap the six Velcro straps that are securing the cables.
-
Open the three cable covers to the fully opened position.
-
Remove the cables from the CMA and set them aside.
-
Disconnect connector D.
-
Press the green release tab (callout 1) on the slide rail latching
bracket toward the left and slide the connector D out of the left
slide rail (1 and 2).
When you slide connector D out of the left slide rail, the slide
rail latching bracket portion of the connector remains in place. You
will disconnect the connector in the next step.
Note -
Once you have disconnected connector D, you must not allow the
CMA to hang under its own weight. Throughout the remainder of
this procedure, the CMA must be supported until all the
remaining connectors are disconnected and the CMA can be placed
on a flat surface.
