Remove the Second-Generation Cable
Management Arm
Follow this procedure to remove the second-generation cable management arm
(CMA).
Before you begin this procedure, refer to FIGURE: Second-Generation CMA
Components on page 53 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.
Note – References to “left” or “right” in this procedure assume that you are facing
the back of the equipment rack.
Note – Throughout this procedure, once you disconnect any of the CMA’s four
connectors, do not allow the CMA to hang under its own weight.
1. To prevent the rack from tipping forward when the server is extended, extend
all rack anti-tilt devices.
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.
For instructions for stabilizing the rack, see “Stabilize the Rack for Installation” on
page 43 .
2. To make it easier to remove the CMA, extend the server approximately 13 cm (5
inches) out of the front of the rack.
3. To remove the cables from the CMA:
a. Disconnect all cables from the rear of the server.
b. If applicable, remove any additional Velcro straps that were installed to
bundle the cables.
c. Unwrap the six Velcro straps that are securing the cables.
d. Open the three cable covers to the fully opened position.
e. Remove the cables from the CMA and set them aside.
