The following figure shows the second-generation CMA components.
Figure 12 Second-Generation CMA Components
1 Connector A
2 Front slide bar
3 Velcro straps (6)
4 Connector B
5 Connector C
6 Connector D
7 Slide-rail latching bracket (used with connector D)
8 Rear slide bar
9 Sun Server X3-2 cable covers
10 Sun Server X3-2L cable covers
The Sun Server X3-2 (1U system) uses the flat cable covers.
The Sun Server X3-2L (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 Sun Server X3-2L, you need to 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:
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 Second-Generation CMA Components.
Figure 13 Removing the CMA Flat Cable Covers
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 Second-Generation CMA Components. This prevents the Velcro straps from interfering with the expansion and contraction of the slide bar when the server is extended out of the rack and returned into the rack.
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.
The connector A tab (see callout 1) goes into the slide-rail's front slot (callout 2).
Gently tug on the left side of the front slide bar to verify that connector A is properly seated.

The connector B tab (callout 1) goes into the slide-rail front slot (callout 2).
Gently tug on the right side of the front slide bar to verify that connector B is properly seated.

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.
Figure 17 Aligning the CMA Slide-Rail Latching Bracket With Connector D
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 rear slide bar to verify that connector D is properly seated.
Figure 18 Installing Connector D Into the Left Slide-Rail
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.
For instructions for stabilizing the rack, see Stabilize the Rack for Installation.
Figure 19 CMA Fully Extended
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 server.
Figure 20 Location of Slide-Rail Release Tabs
You will hear an audible click when the server is in the normal rack position.
Instructions for connecting the server cables are provided in Cabling the Server.
Route the cables through the cable troughs in this order:
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 server is extended from the rack and returned to the rack.
Figure 21 CMA with Cables Installed, Cable Covers Closed, and Cables Secured With Velcro Straps
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 server is extended from the rack and returned to the rack.
