Installing the 7042-CR5, 7042-CR6, 7042-CR7, and 7042-CR8 into a rack

This section describes how to install the 7042-CR5, 7042-CR6, 7042-CR7, or 7042-CR8 HMC into a rack.

Complete a parts inventory. The following illustration shows the items that you need to install the server in the rack cabinet. If any items are missing or damaged, contact your place of purchase.

Note: Screws can be used for shipping, or for additional stabilization in high-vibration areas.

1. Each slide rail is marked with either an R (right) or an L (left). Select one of the slide rails and push up on the front movable tab (1); then, pull out the front latch (2) to slide out the front side rail. If a thumbscrew is installed in the slide rail (3), remove it.

   Note: Make sure that the movable tab remains extended and does not click back into place.
2. Align the three pins on the rear of the slide rail with the three holes in the selected U on the rear of the rack. Push the rails so that the pins go into the holes (1), and drop the slide rail down (2) until it latches into place.

3. Pull the slide rail forward and insert the two pins (1) on the front of the rail into the two lower holes in the U on the front of the rack. Drop the rail into place until it clicks into place. Push the front latch (2) in all the way. Repeat steps 1 through 3 to install the other rail into the rack. Make sure that each front latch is fully seated.

4. Pull the slide rails forward (1) until they click, twice, into place. Carefully lift the server and tilt it into position over the slide rails so that the rear nail heads (2) on the server line up with the rear slots (3) on the slide rails. Slide the server down until the rear nail heads slip into the two rear slots, and then slowly lower the front of the server (4) until the other nail heads slip into the other slots on the slide rails. Make sure that the front latch (5) slides over the nail heads.

5. Lift the blue release latches (1) on the slide rails and push the server (2) all the way into the rack until it clicks into place.

6. The cable-management arm can be installed on either side of the server. The following figure shows it being installed on the left side. To install the cable-management arm on the right side, follow the instructions and install the hardware on the opposite side. Connect one end of the support arm (1) to the same slide rail to which you plan to attach the cable-management arm so that you can swing the other end of the support arm (2) toward the rack.

7. Install the L-shaped cable-management stop bracket (1) on the unattached end of the support arm. Turn the bracket (2) to secure it to the support arm.

8. To attach the other side of the support arm to the backside of the slide rail, pull the pin out (1), and then slide the bracket (2) into the slide rail.

9. Pull out the mounting bracket pin (1) and slide the mounting bracket (2) into the slide rail onto which you are installing the cable-management arm. Push the bracket into the slide rail until the spring-loaded pin snaps into place.

10. Place the cable-management arm on the support arm. Pull out the cable-management arm pin (1), and then slide the cable-management arm tab (2) into the slot on the inside of the slide rail. Push the tab until it snaps into place. Pull out the other cable-management arm pin (3), and then slide that cable management arm tab into the slot (4) on the outside of the slide rail. Push the tab until it snaps into place.

11. Attach the power cords and other cables to the rear of the server (including keyboard, monitor, and mouse cables, if required). Route the cables and power cords on the cable-management arm (1) and secure them with cable ties or hook-and-loop fasteners.
    Note: Allow slack in all cables to avoid tension in the cables as the cable-management arm moves.
