ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: Cable Management Arm (CMA) Replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system.

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc). If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

Caution - Support the CMA during this replacement. Do not allow the assembly to hang by its own weight until it is secured by all three attachment points.

Note - Two people are needed for this procedure, one to move the server in and out of the rack, and one to observe the cables and CMA to see if they move freely and without any unnecessary pinching of cables.

WHAT ACTIONS ARE REQUIRED?:

Prepare the New CMA for Replacement

1. Unpack the CMA.

2. Ensure that the correct cable covers for your server are installed on the CMA.

Note - This server uses the round cable covers.

Note - The CMA ships with three, flat cable covers installed. Before installing the CMA, you must replace the flat cable covers with the round cable covers. If the round cable covers are already on the CMA, skip the next step.

3. (If needed) 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:

a. Lift up on the cable cover handle (the handle is colored green) and open it 180 degrees to the horizontal position.

Note - The CMA has two sets of three cable covers, two covers with two hinges and one cover with a single hinge.

    b. Apply upward pressure to the outside edge of each hinge connector until the hinge connector comes off the hinge.
    c. Repeat above steps to remove all three cable covers.
    d. One at a time, position each round cable cover horizontally over the hinges, and align the hinge connectors with the hinges.
e. Using your thumb, apply downward pressure on each hinge connector to snap the hinge connector into place.
f. Swing the cable covers down and press down on the cable cover handle to lock them into the closed position.

4. 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. 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.

Replace the Damaged CMA

1. Remove damaged CMA.

2. Attach replacement CMA to the Server:
a. To make it easier to install the CMA, extend the server approximately 13 cm (5 inches) out of the front of the rack.
b. Take the CMA to the back of the equipment rack, and ensure that you have adequate room to work at the back of the 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.

    c. Install the CMA's connector A into the left slide rail.
A. Insert the CMA's connector A into the front slot on the left slide rail until it locks into place with an audible click.
B. Gently tug on the right side of the front slide bar to verify that connector A is properly seated.
    d. Install the CMA's connector B into the right slide rail.
A. Insert the CMA's connector B into the front slot on the right slide rail until it locks into place with an audible click.
B. Gently tug on the right side of the front slide bar to verify that connector B is properly seated.
     e. Install the CMA's connector C into the right slide rail.
A. Align connector C with the slide rail so that the locking spring is positioned inside (server side) of the right slide rail.
B. Insert connector C into the right slide rail until it locks into place with an audible click.
C. Gently tug on the right side of the CMA's rear slide bar to verify that connector C is properly seated.
    f. Prepare the CMA's connector D for installation.
A. 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.

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.

g. Install the CMA's connector D into the left slide rail.
A. 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.

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.

B. 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.

h. 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.

i. 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.

3. Verify that the slide rails and CMA operate properly.
