Remove the Cable Management Arm
Follow this procedure to remove the cable management arm (CMA).
Before you begin this procedure, refer to the figure in Step 1, 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.
-
To prevent the rack from tipping forward when the storage server is
extended, extend all rack anti-tilt devices.
![Caution Caution](graphics/caution.gif) | Caution -
To reduce the risk of personal injury, stabilize the rack cabinet and extend
all anti-tilt devices before extending the storage server from the rack.
|
For instructions for stabilizing the rack, see Stabilize the Rack for Installation.
-
Disconnect all cables from the rear of the storage server.
-
To make it easier to remove the CMA, extend the storage server approximately 13 cm
(5 inches) out of the front of the rack.
-
To remove the cables from the CMA:
-
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.
-
To 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 [frames 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
it 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.
