To properly guide the cables to the rear panel of the compute node, a cable management arm (CMA) is used. Pane 7 contains instructions to install the CMA.
Steps:
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.
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.
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.
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.
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.
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.
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.
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.
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.
