Chapter 5 Connect the Pre-Installed Cables to the Server

Steps:

1. To make installation easier, extend the server approximately 13centimeters, or 5 inches, out of the front of the rack. Install the CMA from the back of the rack.

2. Insert the CMA’s connector A into the front slot on the left slide-rail until it locks into place with an audible click.

   An image illustrates how connector A is aligned with the left slide rail and inserted until it locks in place.

3. Insert the CMA’s connector B into the front slot on the right slide-rail until it locks into place with an audible click.

   An image illustrates how connector B is aligned with the right slide rail and inserted until it locks in place. Connector C is still loose at this point.

4. Align connector C with the slide-rail so that the locking spring is positioned inside (server side) of the right slide-rail.

   An image shows connector C from the outside, revealing the locking spring that must be on the inside of the slide rail when the connector is inserted.

5. Insert connector C into the right side-rail until it locks into place with an audible click.

   An image illustrates how connector C is aligned with the right slide rail and inserted until it locks in place behind connector B.

6. 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.

   An image illustrates the installation position of the latching bracket relative to CMA connector D.

7. 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.

   An image illustrates how connector D is aligned with the left slide rail and inserted together with the slide-rail latching bracket until it locks in place.

8. 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.

9. Verify that the slide-rails and the CMA are operating properly before routing cables through the CMA.

   • Extend the server from the front of the rack until the CMA is fully extended.

   • Simultaneously pull and hold the two green release tabs (one on each side of the server) toward the front of the server while you push the server into the rack. As you push the server into the rack, verify that the CMA retracts without binding.

   • Continue pushing the server into the rack until the slide-rail locks (on the front of the server) engage the slide-rail assemblies with an audible click.

   An image shows the server almost fully inserted into the rack. A detail bubble shows the location of the slide rail release buttons. As the arrows indicate, you must push the slide rail release buttons and slide the server into the rack.

Steps:

1. Connect the pre-installed power and data cables of the appropriate rack unit to the back of the expansion node, as indicated in the Server Cabling Requirements on page 1.

2. Open the CMA cable covers, route server cables through the CMA’s cable troughs, close the cable covers, and secure the cables with the six Velcro straps. Start with the front-most cable trough, then through the small cable trough, and finally through the rear-most cable trough.

3. Ensure that the secured cables do not extend above the top or below the bottom of the server to which they are attached; otherwise, the cables might snag on other equipment installed in the rack when the server is extended from the rack or returned to the rack.

   An image illustrates the correct routing of the cables through the cable management arm.

4. Verify the operation of the CMA with all cables installed.

   • Slowly pull the server out of the rack until the slide rails reach their stop.

   • Inspect the attached cables for any binding or kinks.

   • Verify that the CMA extends fully from the slide rails.
