5 Internal Access



This chapter provides information needed to prepare the system for service after the system has been powered off.

To access the power supply and backplane, remove the front panel and EMI shield. To access the other side of the backplane, remove all disk cards and air restrictor panels.

5.1 Front Panel

Remove the front panel to access the EMI shield. The front panel rests in a groove cut on the top front edge of the chassis.

To remove the front panel:

    1. Push up on the latch located on the bottom, center of the front panel.

    Place your fingers under the arrow embossed on the panel. Press up to release the latch. See Figure 5-1.

    Figure 5-1 Removing the Front Panel

    2. When the bottom of the panel is released, gently pull the bottom of the front panel out and lift it off of the chassis. Set the panel aside.

5.2 EMI Shield

To remove the EMI shield:

    1. Loosen four captive retaining screws securing the EMI shield to the chassis.
    2. With your hands on the bottom of the EMI shield, pull the bottom towards you to disengage it from the chassis.

    Set the EMI shield aside. See Figure 5-2.

Caution -

Replace the EMI shield before operating the system. Sun Microsystems Inc. is not responsible for regulatory compliance for a SPARCserver 1000 System which is operated with the EMI panel removed.

    Figure 5-2 Removing the EMI Shield

5.3 Air Restrictor Boards

The system can have up to four boards installed. Slots not occupied by functional boards must have air restrictor boards installed. These air restrictor boards must be removed to access the backplane.

    1. Locate the air restrictor boards at the chassis rear.

    They are simple boards with ejector tabs and no connectors or components.

    2. Remove two screws securing the air restrictor board to the card cage. Set the screws aside for reinstallation.

    See Figure 5-3.

    Figure 5-3 Removing Air Restrictor Board Retaining Screws

    3. Grasp the rounded board extractor tabs on the bottom of the board. Pull the board toward you until it clears the chassis.

5.4 Side Panels

The system side panels are self-attached slide and lock panels.

Note - You need not remove the side panels to access any system component or subassembly.

To remove the side panels:

    1. Remove the front panel as described in Section 5.1.
    2. Grasp one panel with both hands, and slide it towards the chassis rear, then lift the panel off of the chassis.

    In some cases it may be easier to push the front edge of the side panel toward the chassis rear. See Figure 5-4.

    3. Repeat for the other side panel.

    Figure 5-4 Removing the Side Panels

5.5 Top Panel

The top panel slides rearward to a release point, then lifts off.

Note - You need not remove the top panel to access any system component or subassembly.

To remove the top panel:

    1. Remove the front panel as described in Section 5.1.

Remove the Popouts

    1. Remove the four popouts from the top panel:
      a. On the panel, find the location where the two dots are adjacent to each other: one dot on the popout, one on the top panel. See Figure 5-5.
      b. Press down on the popout at the small dot.

      This action rocks the popout on a hinge-point, unlatching it.

      c. Slide the popout back, away from the dots and lift it free as shown in Figure 5-5. Set the popout aside.
    2. Repeat step 1 to remove the remaining three popouts from the top panel.

    Figure 5-5 Removing the Popouts from the Top Panel

Remove the Top Panel

    3. Remove the panel. Use the steps below and refer to Figure 5-6:
      a. Place your fingers under the panel rear lip and lift.

      Lift with enough force to bow the panel rear up at the center. This action causes three small raised features on the panel underside to clear cutouts in the chassis sheet metal.

      b. While lifting the panel rear, tap the front with your hand to slide the panel rearward.

    Slide the panel a few inches only. This is enough to disengage it from the chassis.

Note - If necessary, slide your lifting hand side-to-side under the rear lip while tapping the front to free each of the three raised areas on the panel underside of sheet metal cutouts beneath.

      c. Lift the top panel straight up and clear of the chassis. Set it aside.

Replace the Popouts

    4. Replace the popouts in the top panel to avoid their separation and loss:
      a. Orient the popout so the dots are nearest each other (see Figure 5-7).
      b. Slide the popout in until it is centered in the hole.
      c. Press down on the side opposite the dot to secure the popout in place.
      d. Install the remaining three popouts in the same manner.

    Figure 5-7 Replacing the Popouts in the Top Panel

5.6 Bottom Panel

Note - You need not remove the bottom panel to access any system component or subassembly.

To remove the bottom panel:

    1. Remove the Feet:
      a. Invert the chassis with the front facing you (see Figure 5-8).
      b. Unscrew all four feet and set them aside.

    Figure 5-8 Removing the Feet

    2. Remove the Panel.

    The bottom and top panels are identical part-fabrications and are removed in the same manner. With the chassis inverted and the front facing you, repeat Section 5.5, "Top Panel" step 3 and refer to Figure 5-6 to remove the panel.
