Caution - The server is heavy. Two people are required to lift and mount the server into a rack enclosure when following the procedures in this chapter.




Rackmounting Options

The Sun Netra T5440 server ships with a 19-inch, 4-post hardmount rack kit (see Hardmounting the Server in a 19-Inch 4-Post Rack for installation instructions). The following lists the four additional rackmount kit options that can be ordered from Sun. This chapter provides installation instructions for all of these rackmount kit options.

    FIGURE 3-2   Securing the Hardmount Brackets to the Server




  3. Measure the depth of the rack.

  4. Get the two rear mount support brackets from the rack kit.

  5. Install the rear mount support brackets at the rear of the server, extending the rear mount support brackets to the measured depth of the rack.

    Use two to three of the supplied M5 x 8 mm panhead Phillips screws for each bracket, depending on the rack depth. If your rack is especially deep, you might only be able to secure the rear mount support brackets using two screws per side.

    FIGURE 3-3   Attaching the Rear Mount Support Brackets




  6. Lift the server to the desired location in the rack.



    Tip - It is strongly suggested to use a mechanical lift for your safety and safe-handling of the server.



  7. Using three screws per side, secure the front hardmount brackets attached to the sides of the server to the front of the rack.

    The size of the screws varies, depending on your particular rack.

    FIGURE 3-4   Securing the Front of the Server to the Rack

If the spacing exceeds the maximum measurement, install the rail extenders as described in To Install the Long Bracket Extenders .



procedure icon  Mounting the Server in a 19-Inch 4-Post Rack With Sliding Rails

  1. Get the hardmount brackets and M5 x 8 mm flathead Phillips screws from the rack kit (FIGURE 3-6).

  2. Using four of the supplied M5 x 8 mm flathead Phillips screws (two screws for each bracket), secure the hardmount brackets to the sides of the server (FIGURE 3-7).

    FIGURE 3-7   Securing the Hardmount Bracket to the Server




  3. Get the Telco slide assemblies from the rack kit (FIGURE 3-6).

  4. Press in the button on each slide and pull the glide completely out of the slide (FIGURE 3-8).

    FIGURE 3-8   Dismantling the Slide

    FIGURE 3-9   Securing the Guides to the System Chassis




  6. Get the short brackets and long brackets from the rackmount kit (FIGURE 3-6).

  7. Lift each short bracket to the desired position at the front of the rack and attach a short bracket to each of the front rack uprights (FIGURE 3-10).

    Use two of the brass M6 collar screws and M6 cage nuts (if required) to secure each bracket.

    FIGURE 3-10   Securing the Short Brackets to the Front of the Rack




  8. Lift each long bracket to the desired position at the rear of the rack and attach a long bracket to each of the rear rack uprights (FIGURE 3-11).

    To secure each bracket, use two of the brass M6 collar screws and M6 cage nuts (if required), exactly as you did for the front rack uprights in the previous step.



    Note - If the dimension is greater than 755.7 mm, attach the rail extenders to the long brackets as described in To Install the Long Bracket Extenders.



    FIGURE 3-11   Securing the Long Brackets to the Rear of the Rack




  9. Extend a slide to line up the access holes with the front screw holes.

  10. Using the M5 panhead screws (four for the short bracket and four for the long bracket), secure the slide onto the short and long brackets at the front and rear of the rack (FIGURE 3-12).

    FIGURE 3-12   Securing the Slide to the Brackets




  11. Repeat Step 9 and Step 10 for the slide on the other side of the rack.

  12. Push the slides completely into the assembly on each side of the rack and release the stop catches.

  13. Align the glides attached to the system with the slide assemblies in the rack.You might find that there is too much or too little room between the two slides mounted in the rack. The glides attached to the system also might not align correctly with the slides in the rack. If either situation occurs, loosen the M6 collar screws and cage nuts on the long and short brackets (Step 7 and Step 8), move them inward or outward to the appropriate points, then tighten the servers again.

  14. Push in the slide buttons and slide the system all the way into the rack enclosure (FIGURE 3-13).

    FIGURE 3-13   Sliding the System Into the Rack




  15. Using one screw per side, secure the front of the hardmount brackets that are attached to the sides of the server to the front of the rack (FIGURE 3-14).

    The size of the screws varies, depending on your particular rack.

    FIGURE 3-14   Securing the Front of the Server to the Rack




procedure icon  To Install the Long Bracket Extenders

Use this procedure to attach the long bracket extenders to the long brackets and slide assemblies. See for mounting details when using this procedure.



Note - If the long brackets are already attached to the slide assembly, you might have to remove the long brackets and reinstall them using this procedure.



  1. Locate the long bracket extenders.

    The extenders are shorter than the long brackets and do not have clip nuts attached.

  2. Place an extender and slide assembly inside a long bracket.

  3. Install two M5 panhead screws through the rear set of holes in the slide assembly and into the front clip nuts in the center slots of the long bracket.

    Tighten the screws.

  4. Install two M5 panhead screws through one of the front set of holes in the slide assembly and into the matching clip nuts in the long bracket.

    Tighten the screws.

  5. Install two M5 panhead screw through the front slots of the bracket extender and into the rear clip nuts in the center slots of the long bracket.

    Hand tighten the screws.

  6. Install the two M5 panhead screws through the center slot of the bracket extender and into the matching clip nuts on the long bracket.

    Hand tighten the screws.

    FIGURE 3-15   Installing Extender and Slide Assembly on Long Bracket




  7. Secure the extender brackets and slide assemblies in the rack as shown in (FIGURE 3-16).

    Adjust the rails to the proper length, tighten the screws on the extenders, and install four M6 collar screws (two in front bracket and two in the rear bracket) for each sliding rail assembly.
