Exchange the management console display/keyboard

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This is not a stand-alone procedure. Customer disruption and damage to the hardware might occur if microcode and power boundaries are not in the proper conditions for this service action.
  • If you were sent here by a serviceable event FRU repair, the microcode and power boundaries have already been set.
  • If you were not sent here by a serviceable event FRU repair, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Remove the management console display/keyboard

About this task

Procedure

  1. To locate this FRU, do one of the following and then return here and continue to replace the FRU:
    • If this FRU has a FRU identify indicator, use the FRU identify indicator, which is listed in MAP1240 Locating FRUs using identify indicators. If not, use the location code.
      Note: There might be cases where the FRU failure or fencing conditions prevent the FRU LED indicator from being lit even if the FRU has power.
    • Use the location code, which is listed in MAP1245 Finding FRUs by using location codes.
    • If there is no FRU identify indicator or location code, you were sent here by an isolation MAP or symbolic FRU procedure. Use the information in that procedure and the figures in this procedure to locate the proper part to exchange.
  2. Most, but not all, FRUs have identify indicators. Use the flashing amber or solid blue FRU identify indicators to ensure that you are working on the correct enclosure or FRU.
    • The "light path" identify LEDs are a hierarchy of LEDs that can identify the rack, enclosure, FRU, and even the FRU connector to which a cable is connected.
    • For more information, refer to MAP1240 Locating FRUs using identify indicators.

About this task

Note: Ensure the management console has been shutdown. Go to step 3 above, then return here.

Procedure

  1. Set the new management console keyboard/display on a work surface. Unscrew the two black thumbscrews at the display end, so you can pull the display and make the rails full length. See Figure 8.
  2. Loosen, but do not remove, the rail length adjustment screw Callout label 1 on each rail. This will allow you in a later step to adjust the length once it is in the rack.

    2. Ensure the cables are not damaged as you do this.
  4. At the rear of the rack, squeeze the rails towards each other so they can go past the vertical rack mount surfaces.
  5. At the front of the rack, install and tighten the four screws that fasten the rails to the rack mount surface.
  6. At the rear of the rack, install and tighten the two left screws and the upper right screw that fasten the rails to the rack mount surface. Install the right bottom screw but leave it two turns loose.
  7. Install the 208V multi-cable sliding it under the two screws Callout label 1 and then tighten the screws. See Figure 6.
  8. Reach in and tighten the rail length adjustment screw on each rail.
  9. Connect the three connectors Callout label 1 between the management console keyboard/display integrated cable Callout label 3 and the management console keyboard/display cable Callout label 2. See Figure 4.
  10. Connect the management console keyboard/display power cable Callout label 1 to the rack power cable The management console server will automatically power on. See Figure 3.
  11. At the front of the rack, ensure the keyboard/display tray can be pushed in and the two black thumbscrews tightened.
  12. Put the keyboard/display in the service position with the display up. Press the display power key Callout label 2 and ensure the power LED Callout label 1 is on. See Figure 1.
