Installing the 7042-CR9 HMC into a rack

Learn how to install the 7042-CR9 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 need both the slide rail box and the cable management arm box for this installation.

1. Select an available space (depending on the server you are installing) in your rack to install your server.
   Figure 3. Identifying a rack space
   Note: You need 1 unit (1 U) of space and the slide rails are installed in the bottom unit (U) of the 1 unit of space.
2. Extend the outer slide member all the way back until you hear an audible click. The rear rack mount bracket is now rotated into the unlocked position.
   Figure 4. Slide rail and the outer slide member
   Note: Each slide rail is marked as R (right) or L (left) on its end.
3. Align the rear end of the outer slide member against the holes on the rear of the rack. Line up the pins and push the slide in so that the pins go into the holes. The two slide pins protrude through the top and bottom holes on the EIA flange. Push the slide towards the rear of the rack until the rear rack mount bracket locks into place.

4. Rotate the front latch to the open position and align the front end of the outer slide member against the holes on the front of the rack. Line up the pins with holes in the EIA flanges and pull the slide forward so that the pins protrude through the holes. Lock the front of the slide by allowing the front latch to rotate to the closed position. Repeat steps 2- 4 for the other outer slide member.

5. Press on the release latches (1). When you move the rack cabinet, or if you install the rack cabinet in a vibration-prone area, tighten the captive M5 screws (2) in the front of the server.

6. 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 slots in the slide rails. Lower the server down until the rear nail heads slide 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. Ensure that the front latch covers the front nail head so that the system is secured to the slide rails.

   Note: Use safe practices while lifting. If you are installing a 1 U server, ensure that you have two people when you lift the server. Their hands must be positioned as illustrated in Figure 8.
7. 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.

8. The cable-management arm can be installed on either side of the server. Figure 10 shows it being installed on the left side. It is best to install the cable-management arm so that it hinges on the side opposite to the power supplies to provide access to the power supplies. To install the cable-management arm on the right side, follow the instructions and install the hardware on the opposite side. Place the pin down (1) into the horizontal slot on the rear of the slide rails. Then rotate the other end of the bar toward the rack (2) toward the rack.
   Figure 10. Support arm connection
   Note: The cable management support bar must be on top of the slide tab to work correctly.
9. 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 11. Connecting the stop bracket to the slide rail
   Note: The capital letter O is marked on cable management arm pins to identify the outside pins.
10. Place the cable-management arm on the support arm. 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 place.
    Figure 12. Cable-management arm connection
11. 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 cable management support.

12. 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 14. Attaching the Power cord and routing the cable
13. Cables must be bundled with the cable strap 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.

14. If you are shipping the rack with the system installed or if you are in a vibration-prone area, insert the M5 screws into the rear of the slides. Use a cable tie to secure the free end of the cable management arm to the rack if needed.
