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 correct cable covers for your server are installed on the
CMA.
The Oracle Exadata Storage Server X5-2 Extreme Flash (2U system) uses the round cable covers.
Note -
The CMA ships with three flat cable covers installed. If you are going to
install the CMA on a Oracle Exadata Storage Server X5-2 Extreme Flash, remove the flat cable covers and install the
round cable covers.
-
Remove the flat cable covers and install the round cable covers.
To remove the flat cable covers and install the round cable covers, perform these
steps:
-
Lift up on the cable cover handle (the handle is colored green) and open it
180 degrees to the horizontal position as shown in the following figure [frames
1 and 2].
Note -
The CMA has three cable covers, two with two hinges (one of which is
shown the following figure), and one with a single hinge. All three cable
covers are shown in the illustration in
Step 1.
-
Apply upward pressure to the outside edge of each hinge connector until the
hinge connector comes off the hinge [frame 3].
-
Repeat Step 3.a and Step 3.b to remove all three cable
covers.
-
One at a time, position each round cable cover horizontally over the hinges,
and align the hinge connectors with the hinges.
-
Using your thumb, apply downward pressure on each hinge connector to snap
the hinge connector into place.
-
Swing the cable covers down and press down on the cable cover handle to lock
them into the closed position.
-
Ensure that the six Velcro straps are threaded into the CMA.
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 illustration 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.
-
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 (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 (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.
Refer to the Oracle Exadata Database Machine documentation for
instructions.
-
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.
