Install the CMA

To install the CMA, follow this procedure:

  1. Using tape or a marker, make two horizontal marks, one on each of two rack posts. These marks must be level because they will indicate where the CMA will be attached to the rack.
  2. Slide the attachment bracket over the extender, so that the tab on the bracket is opposite the flange on the extender as shown in Attachment Bracket sliding over the Long Rail.

    The open end of the tab is toward the flange. The flat end of the tab is toward the rear of the extender.

  3. Place the attachment plate on the flange side of the extender, opposite the attachment bracket.
  4. Use two M4 screws to sandwich the attachment bracket and plate to the extender, in the position farthest from the flange as shown in Bracket and Plate Sandwiching to the Rail.

  5. Using a No. 2 Phillips screwdriver, tighten the two screws.
  6. Repeat Step 2 through Step 5 for the other cable management extender.
  7. Place the long rail to the mounting location (see Step 1) on the post of the rack. Make sure that these rails are flush with the side of the Fabric Interconnect chassis, with the flange pointing outward as shown in front brackets being installed.

  8. Secure the assembly to the post with the correct screw type for the rack (10-32, 12-24, or M6) by inserting the screw through the slotted end of the CMA and into the rack or cage nut.
    Note - If you are installing into a rack tapped for 12-24 screws, you must use the accompanying #12 lock washers. For 12-24 racks, insert the screw into the lock washer before installing the screw into the rack.
  9. Repeat Step 7 to Step 8 for the other cable management extender and long rail.
  10. If needed, disassemble the CMA comb and plate by loosening the green captive screws.
  11. Align the green captive screws in the comb with the two screw holes in the tabs as shown in Installing the CMA's Comb.

    Figure 19  Installing the CMA's Comb


    image:Figure shows the CMA comb slides onto the ends of the CMA rails, with one captive screw on each side.
  12. Using a Phillips-head screwdriver, tighten the green captive screws to attach the comb to the standoffs.
  13. When the CMA's comb is installed, connect cables and drape them into the slots in the comb as shown in Connecting Cables and Draping Them Through the Comb.
    Note - Make sure not to exceed the allowed bend radius for any cables you route through the comb. Also, wherever possible, make sure to drape equal numbers of cables in each slot to apply the cable weight equally along the CMA.

    image:Figure shows I/O cables passing through the vertical posts on the CMA comb.
  14. When all cables are connected, align the captive screws in the top of the CMA with the screw holes in the CMA's comb as shown in Installing the Top of the CMA.

    image:Figure shows the top cover of the CMA attaches with captive screws to the CMA, to hold down I/O cables.
  15. Using a Phillips-head screwdriver, tighten the screws to secure the plate to the comb as shown in Completing Assembly of the CMA.
