Installing the 7042-CR7 and 7042-CR8 into a rack

Learn how to install the 7042-CR7 and 7042-CR8 Hardware Management Console (HMC) into a rack.

Complete a parts inventory. The following illustrations show 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: You will need both the slide rail box and the cable management arm box for this installation.

1. Select an available 1 unit or 2 unit space (depending on the server you are installing) in your rack to install your server.
   Figure 3. Identifying a rack space
   Note: When you install a 2 unit server, be sure to install the slide rails in the lower U of the 2 U area in the rack.
2. Each slide rail is marked as Left Front/Rear or Right Front/Rear on its end. Select one of the slide rails and pull the rear bracket all the way back until it clicks into place.
   Figure 4. Slide rail and the movable tab
   Note: Ensure that the movable tab remains extended and does not click back into place.
3. From the front of the rack, line up the two pins on the rear of the slide rail in the selected U on the rear of the rack. Push the rails so that the pins go into the holes and slide the rails into the rack to lock the rear of the slide rails into the rack.
   Figure 5. Align the pins with the holes in the rear of the rack
   Note: If you are installing the slide rails into a 1 U space with devices already installed directly above and below this 1 U space, you must extend the rails to slide the rear of the slide rails into the rear of the rack.
4. Open the front slide rail latch. If they are closed when you receive them, open the latches by pushing the blue button in and by pushing the latch back.

5. Pull the slide rails forward and locate the front latches in the appropriate U spaces in front of the rack EIA rails. Adjust the length of the rails. Ensure that the front end is being rotated into position with the front latch in front of the EIA rail of the rack.
   Figure 7. Rack front rail and pins
6. Press the blue button to close the bracket with the pins. Moving the slide rail up and down to ensure that the rail is fully engaged. Repeat steps 1 - 5 to install the other rail into the rack. Ensure that each front latch is fully engaged.

7. 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 such that the rear nail heads (2) on the server line up with the rear slots on the slide rails. Lower the server down until the rear nail heads slip into the two rear slots, and then slowly lower the front of the server (3) until the other nail heads go into the other slots on the slide rails (by hearing the clicks twice). Ensure that the front latch covers the front nail head such that the system is secured to the slide rails.

   Figure 10. Lift points
   Note: Use safe practices while lifting. If you are installing a 2 U server, ensure that you have two people when lifting the server. Their hands must be positioned as illustrated in Figure 10.
8. Lift the locking levers (1) on the slide rails and push the server (2) all the way into the rack until it clicks into place.

9. 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.
   Figure 12. Support arm connection
10. Connect the other end of the support arm to the cable-management stop bracket (1). Turn the bracket (2) to secure it to the support arm.
    Figure 13. Cable-management stop bracket secured to the support arm
11. The capital letters I and O are printed on cable management arm pins to identify the inside and outside pins. Install the cable management stop bracket (with capital letter O) on the unattached end of the support arm. Ensure that the support arm is securely installed.
    Figure 14. Connecting the stop bracket to the slide rail
12. Place the cable-management arm on the support arm. Pull out both the inside and the outside pins of the cable management arm and then slide the cable management arm tabs into both the inside and the outside slots of the slide rail. Push the tabs until they snap into places.
    Figure 15. Cable-management arm connection
13. To make it easier to rotate the cable management arm on and off the cable management support arm, you can open the stop bracket by pushing the tabs above and below the stop bracket for closing it.
    Figure 16. Cable management support stop bracket
14. 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 and secure them with cable ties or hook-and-loop fasteners.
    Note: The location of the cable straps might be slightly different in different systems. Use the cable straps that are provided on the rear of the system to retain the cables and prevent them from sagging.
    Figure 17. Power cord attachment and cable routing
15. Cables must be bundled with a hook-and-loop fastener for proper movement of the cable management arm.
    Note: Ensure that the cables do not sag below the U space so they do not get caught on the lower systems. Allow slack in all cables to avoid tension in the cables as the cable-management arm moves.
    Figure 18. Hook-and-loop fastener
16. If you are shipping the rack with the system installed or if you are in a vibration-prone area, insert the M6 screws to the rear of the slides. Use a cable tie to secure the free end of the cable management arm to the rack if needed.
