Lock nuts Rear bracket Rear bracket 10-32 screws Outer slide

19 Note – Four screw holes are provided in the outer slide. Depending on the cabinet depth, you may need to move one (or both) of the 10-32 screws to another of the four screw holes. Be sure to use both screws to secure each rear bracket to the outer slide. d. Tighten the two 10-32 screws and lock nuts on each slide to resecure the rear brackets to the outer slides. Determine the Vertical Position of the Server in the Cabinet Plan to install the tray assembly in the lowest available position in the cabinet. If you are installing two Sun Fire 880 servers in the cabinet, install the lower server first. To determine the vertical position of the server, identify which cabinet rail holes to use for attaching the front and rear brackets by completing the following steps: 1. Locate and mark the correct holes on the right and left front vertical cabinet rails. Make sure there is enough vertical space to install the server. Note – Each Sun Fire 880 server requires 17 rack units (29.75 inches) or 51 holes on the vertical rails of the cabinet. A standard 72-inch high cabinet can accommodate two Sun Fire 880 servers. If the Sun Fire 880 server will be installed immediately above a power sequencer, leave at least one free hole above the sequencer. Using masking tape or a felt tip pen, mark the lowest available hole for installing the tray on the right front vertical rail of the cabinet. The second free hole is the lowest available hole if you are installing the Sun Fire 880 server immediately above a power sequencer. Mark the matching hole on the left front rail of the cabinet. Count the holes to be sure you are using matching holes on the right and left rails of the cabinet. 2. Locate and mark the corresponding holes on the right and left rear vertical cabinet rails. Using masking tape or a pen, mark the matching holes on the right and left rear vertical rails. Count the holes to be sure you are using the holes that match the ones you marked in step 1.

Attach the Tray Assembly to the Cabinet Using the rail holes you marked in “Determine the Vertical Position of the Server in the Cabinet” on page 19, attach the tray assembly to the cabinet by completing the following steps: 1. Attach the front brackets on the slides of the tray assembly to the front rails of the cabinet. a. With the help of an assistant, position the tray assembly on the inside of the cabinet with the front brackets at the front of the cabinet. To fit the tray assembly between the rails, you will need to tilt it by lowering one side of the assembly.

21 b. Attach the front brackets to the front rails of the cabinet using four 10-32 screws. Align the lower hole of each front bracket with the front rail holes you marked in “Determine the Vertical Position of the Server in the Cabinet” on page 19. Secure the front brackets using one 10-32 screw in the lower hole of each bracket. Finger-tighten the screws. Align the upper hole of each front bracket with the corresponding hole in the cabinet rail. Secure the brackets to the rail using one 10-32 screw in each upper hole. Finger-tighten the screws. Do not tighten the screws completely until all the screws are in place and the tray assembly is level.

2. Attach the rear brackets to the rear rails of the cabinet using four 10-32 screws. Align the lower hole of each rear bracket with the rail hole you marked in “Determine the Vertical Position of the Server in the Cabinet” on page 19. Secure the brackets using one 10-32 screw in each lower hole. Finger-tighten the screws. Align the upper hole of each rear bracket with the coinciding hole in the cabinet rail. Secure the bracket to the rail using one 10-32 screw in each upper hole. Finger-tighten the screws. Do not tighten the screws completely until all the screws are in place and the tray assembly is level. 3. Make sure the tray assembly is level. Use a level to ensure the tray assembly is level front-to-back and left-to-right. Adjust as necessary. 4. Once the tray assembly is level, completely tighten all of the bracket screws. Tighten the eight 10-32 screws that secure the front and rear brackets to the vertical cabinet rails. 5. Slide the tray assembly in and out of the cabinet to be sure the slides operate smoothly.

23 Installing the Server Into the Tray Assembly 1. Be sure the cabinet is stabilized so that the cabinet cannot move or tip forward when the tray is extended and the server is placed on the tray. If there are feet beneath the cabinet to prevent it from rolling, be sure the feet are fully extended downward to the floor. Stabilize the cabinet using the stabilizing mechanisms provided with the cabinet. See the instructions provided with the cabinet. Caution – Before you slide the tray out, be sure the cabinet is stabilized so that it cannot move or tip forward. See the cabinet documentation for information about stabilizing the cabinet. Caution – Do not attempt to lift the server until you remove all CPU/Memory boards, all power supplies, all CPU fan trays, and all I/O fan trays. Once these components are removed, four persons are required to lift the server. See “Preparing the Server” on page 8 for information about removing these components. ! Some cabinets may be equipped with stabilizers or bolt-down mechanisms. See the cabinet documentation for stabilizing instructions. Stabilizers !

2. Extend the tray all the way forward. Standing in front of the cabinet, grasp the tray handle and pull the tray toward you until it stops. Caution – Do not place your fingers on the tray or under the server while you are lifting the server and positioning it on the tray. 3. Place the server on the tray. a. Lift the server (two persons on each side of the server) by the lifting handles that you installed in “Preparing the Server” on page 8. b. Position the server on the tray so that the front of the server is at the front of the tray and the back of the server is at the back of the tray. 4. Adjust the server on the tray until the four holes on each side of the server align with the four holes in the tray assembly. ! Tray Align the four screw holes on the tray with the four screw holes on the server.

25 5. Remove the four lifting handles from the sides of the server. a. Insert the screwdriver through one of the access holes on the outside of the handle. Using the access hole makes it easier to reach the opposite screw hole on the inside of the handle to remove the screw. See the following figure. b. Remove the two M4 screws that attach each handle to the server. c. Save the eight M4 screws you remove. You will need to use the screws in step 7. 6. Secure the handles to the rack for safekeeping. You must reattach the handles if you need to remove the server from the cabinet.

7. Secure the server to the tray assembly using the eight M4 screws you removed in step 5. Use four M4 screws on each side of the server as shown in the following figure. Do not tighten the screws until all screws are in place and you check the placement of the server. Tray Tray

27 8. Check that the server is level and centered on the tray. Use a level and adjust the server position if necessary. 9. Tighten the eight M4 screws that secure the server to the tray assembly. Restoring the Server 1. Install the CPU/Memory boards and fan trays that you removed before you installed the server into the cabinet. See the Sun Fire 880 Server Service Manual for instructions to install components. 2. If you removed the server’s side doors, replace them. Caution – Avoid keeping the server’s doors open for extended periods while the system is operating. Server doors must be closed to prevent automatic thermal shutdown. 3. Close both of the server’s side doors securely. 4. Slide the tray assembly into the cabinet. 5. Install the power supplies that you removed before you installed the server into the cabinet. See the Sun Fire 880 Server Service Manual for installation instructions. !

Securing the Server in the Cabinet To secure the tray assembly and server in the cabinet, attach the tray handle to the front rails of the cabinet. 1. Attach the tray handle to the front rails of the cabinet. Use one or two 10-32 screws to attach the tray handle to the front rails. If each of the two screw holes on each side of the handle aligns with a rail hole, use two 10-32 screws to attach each side of the tray handle to each front rail as shown in the following figure. If only one screw hole on each side of the handle aligns with a rail hole, use one 10-32 screw to attach each side of the tray handle to each front rail. 2. Locate the Sun Fire 880 server key.

29 3. Lock the system in the cabinet. Insert the Sun Fire 880 server key into the keylock on the tray handle and turn the key 90 degrees counterclockwise. Locking the tray handle extends the security plates so that they cover the screw heads on each side of the tray handle. The security plates prevent removal of the screws that secure the tray and the server to the cabinet. 4. Remove and safeguard the key. Installing Trim Strips The lower decorative panels (trim strips) were removed when you removed the lower side panels. To restore the trim strips: 1. Locate the two trim strips provided in the rackmounting kit. 2. Attach one trim strip to the right front cabinet rail and one trim strip to the left front cabinet rail. Using the two captive screws, attach each trim strip as shown in the following figure. If only one screw on each trim strip aligns with a rail hole, use one screw to attach each trim strip to each front rail.

Restoring the Cabinet 1. Replace the front and back doors of the cabinet, if applicable. See the instructions provided with the cabinet. 2. If you removed the side panels from the cabinet, do not replace them until you connect and route the server cables. Caution – To prevent the cabinet from tipping forward, do not attempt to roll or move the cabinet after installing the server in the cabinet. Managing Cables You will need to develop a cable management scheme that is customized for your installation. The Sun Fire 880 server rackmounting kit provides several tools that may aid you in managing the server power cords and cables: I Cable management bracket (with integrated releasable tie wraps) that attaches to the rear of the server. See “Attach the Server Cable Management Bracket” on page 16. I Cable management bracket (with separate releasable tie wraps) that attaches to the rear of the cabinet. See “Attach the Cable Management Bracket to the Cabinet” on page 31. I Three universal power jumper cords that enable you to provide additional slack in the server power cords. See the following general guidelines for more information. In addition, some cabinets have cable management features or optional cable management accessories. The following are general guidelines for routing and managing the server cables: I Allow enough slack in the server power cords and cables so that the tray assembly can be fully extended from the front of the cabinet for service access. If the server power cords are too short for your particular installation, three universal jumper cords, provided with the rackmounting kit, allow you to gain the additional slack needed. One end of a jumper cord plugs into a Sun Fire 880 server power supply; the other end of the jumper cord plugs into a Sun Fire 880 server power cord. The server power cord then plugs into an AC power source. !

31 I To prevent bending or pinching of the cables when the tray assembly is fully extended, be sure that all cables are kept clear of the slides and other obstructions. I When connecting the power jumper cords to the server’s power cords, use tie wraps to secure each connection, as shown below. Attach the Cable Management Bracket to the Cabinet The cable management bracket that attaches to the rear of the cabinet may help to provide strain relief for the power cord and other server cables. Releasable tie wraps provided with the rackmounting kit can be used to secure the cables. See “Managing Cables” on page 30 for general cable management guidelines. To attach the cable management bracket to the rear of the cabinet, complete the following steps: 1. Locate the cable management bracket for the cabinet. This bracket was provided with the rackmounting kit.

2. Attach the bracket to one of the rear rails of the cabinet as shown in the following figure. Use two 10-32 screws to attach the bracket to the cabinet rail. You can attach the bracket to either the right or left rear rail of the cabinet and at any location on the rail that suits your cable management scheme. What Next Connect the server power cords, network cables, and I/O interface cables to the server and route the cables, allowing enough slack for service access. See “How to Install the Sun Fire 880 Server” in the Sun Fire 880 Server Owner’s Guide. Note – A grounding screw is located just above the server’s center power supply. Be sure to ground the server to the cabinet using an appropriate grounding strap. Proper grounding prevents ground loops between systems and peripherals and helps guard against possible data loss.

If the doors of the cabinet do not meet the open area requirements, remove the door or doors that do not comply. Vertical Mounting Rail Requirements The cabinet must have two pairs of vertical mounting rails (one pair in front, one in back) that conform to the EIA (RETMA) standard for mounting hole spacing. Front-to-rear rail spacing must be at least 32 inches (81.3 cm) and not more than 36 inches (91.4 cm) from the outside face of the front rail to the outside face of the rear rail. Front and rear vertical rail mounting faces must be parallel to each other and to the front plane of the cabinet. Doors and Panels Depending on your cabinet, you may need to remove the front and rear door and side panels to access the server or to provide proper ventilation. See Minimum Service Access requirements and Airflow requirements given previously in this appendix. See the instructions provided with the cabinet for information about removing the front and rear doors and side panels from the cabinet. EMI Requirements Electromagnetic interference (EMI) shielding requirements are met by the system chassis and metal side doors, which must remain in place when the unit is installed in the cabinet.
