Install the Cable Management Arm
Follow this procedure to install the cable management arm (CMA), which you can use to
manage cables connected to the rear of the storage server.
-
Unpack the CMA.

-
Ensure that the flat cable covers are installed on the CMA.
-
Ensure that the six Velcro straps are threaded into the CMA as shown in the figure
in Step 1.
Note -
Ensure that the two Velcro straps located on the front slide bar are threaded
through the opening in the top of the slide bar as shown in the figure in
Step 1. This prevents the Velcro straps from interfering
with the expansion and contraction of the slide bar when the storage server is
extended out of the rack and returned into the rack.
-
To make it easier to install the CMA, extend the storage server approximately 13
cm (5 inches) out of the front of the rack.
-
Take the CMA to the back of the equipment rack, and ensure that you have adequate
room to work at the back of the storage server.
Note -
References to “left” or “right” in this procedure
assume that you are facing the back of the equipment rack.
Note -
Throughout this installation procedure, support the CMA and do not allow it to
hang under its own weight until it is secured at all four attachment
points.
-
To install the CMA's connector A into the right slide-rail:
-
Insert the CMA's connector A into the front slot on the left slide-rail
until it locks into place with an audible click [frames 1 and 2].
The connector A tab (see callout 1) goes into the slide-rail's front slot
(callout 2).
-
Gently tug on the right side of the front slide bar to verify that connector
A is properly seated.

To install the CMA's connector B into the right slide-rail:
-
Insert the CMA's connector B into the front slot on the right slide-rail
until it locks into place with an audible click [frames 1 and 2].
The connector B tab (see callout 1) goes into the slide-rail's front slot
(callout 2).
-
Gently tug on the right side of the front slide bar to verify that connector
B is properly seated.

To install the CMA's connector C into the right slide-rail:
-
Align connector C with the slide-rail so that the locking spring (callout 1)
is positioned inside (storage server side) of the right slide-rail [frame
1].

-
Insert connector C into the right slide-rail until it locks into place with
an audible click [frames 2 and 3].
-
Gently tug on the right side of the CMA's rear slide bar to verify that
connector C is properly seated.
-
To prepare the CMA's connector D for installation, remove the tape that secures
the slide-rail latching bracket to connector D and ensure that the latching bracket
is properly aligned with connector D [frames 1 and 2].
Note -
The CMA is shipped with the slide-rail latching bracket taped to connector
D. You must remove the tape before you install this connector.
-
To install the CMA's connector D into the left slide-rail:
-
While holding the slide-rail latching bracket in place, insert connector D
and its associated slide-rail latching bracket into the left slide-rail until
connector D locks into place with an audible click [frames 1 and 2].
Note -
When inserting connector D into the slide-rail, the preferred and easier
method is to install connector D and the latching bracket as one assembly
into the slide-rail.
-
Gently tug on the left side of the CMA's slide bar to verify that connector
D is properly seated.
Note -
The slide-rail latching bracket has a green release tab. This tab is used
to release and remove the latching bracket so that you can remove connector
D.
-
Gently tug on the four CMA connection points to ensure that the CMA connectors are
fully seated before you allow the CMA to hang by its own weight.
-
To verify that the slide-rails and the CMA are operating properly before routing
cables through the CMA:
-
Extend all rack anti-tilt devices to prevent the rack from tipping
forward when the storage server is extended.
| 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.
-
Extend the storage server from the front of the rack until the CMA is fully
extended.
-
To return the storage server to the rack:
-
Simultaneously pull and hold the two green release tabs (one on each side of
the storage server) toward the front of the storage server while you push the
storage server into the rack. As you push the storage server into the rack,
verify that the CMA retracts without binding.
Note -
To pull the green release tabs, place your finger in the center of each
tab, not on the end, and apply pressure as you pull the tab toward the front
of the storage server.
-
Continue pushing the storage server into the rack until the slide-rail locks
(on the front of the storage server) engage the slide-rail assemblies.
You will hear an audible click when the storage server is in the normal rack
position.
-
Connect cables to the storage server, as required.
Instructions for connecting the storage server cables are provided in Cabling the Storage Server.
-
Open the CMA cable covers, route storage server cables through the CMA's cable
troughs, close the cable covers, and secure the cables with the six Velcro
straps.
Route the cables through the cable troughs in this order:
-
First through the front-most cable trough.
-
Then through the small cable trough.
-
Then through the rear-most cable trough
Note -
When securing the cables with the Velcro straps located on the front
slide bar, ensure that the Velcro straps do not wrap around the bottom of
the slide bar; otherwise, expansion and contraction of the slide bar might
be hindered when the storage server is extended from the rack and returned
to the rack.
-
Ensure that the secured cables do no extend above the top or below the bottom of
the storage server to which they are attached; otherwise, the cables might snag on
other equipment installed in the rack when the storage server is extended from the
rack or returned to the rack.
Note -
If necessary, bundle the cables with additional Velcro straps to ensure that
they stay clear of other equipment. If you need to install additional Velcro
straps, wrap the straps around the cables only, not around any of the CMA
components; otherwise, expansion and contraction of the CMA slide bars might be
hindered when the storage server is extended from the rack and returned to the
rack.
-
Proceed to Verify Operation of Slide-Rails and CMA.
