7.Replace the clear plastic cover.

8.Replace the top cover. See “Replacing the Top Cover” (page 182).

9.If rack installed, slide the server completely into the rack. See “Inserting the Server into the Rack” (page 180).

10.Reconnect the power cables and power on the server. See “Powering On the Server” (page 94).

Removing and Replacing the Interconnect Board

The interconnect board attaches the midplane board to the display board and the SAS backplane board.

WARNING! Ensure that the system is powered off and all power sources have been disconnected from the server prior to performing this procedure.

Voltages are present at various locations within the server whenever an ac power source is connected. This voltage is present even when the main power switch is in the off position.

Failure to observe this warning can result in personal injury or damage to equipment.

CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety precautions can result in damage to the server.

IMPORTANT: System information is stored on the interconnect board. You must write serial number and model string information to the new interconnect board after installation.

Removing the Interconnect Board

To remove the interconnect board, follow these steps:

NOTE: Use the guide posts located on the chassis and the keyways located on the interconnect board to help you with the interconnect board removal and replacement procedures.

1.Power off the server and disconnect the power cables. See “Powering Off the Server” (page 95).

2.If rack installed, slide the server completely out from the rack. See “Extending the Server from the Rack” (page 180).

3.Remove the top cover. See “Removing the Top Cover” (page 181).

4.Remove the air baffle (Figure 6-33).

5.Remove the clear plastic cover.

6.Disconnect the USB cable from the connector on the display board (Figure 6-30).

7.Remove the DVD drive. See “Removing the DVD Drive” (page 202).

8.Remove the display board. See “Removing the Display Board” (page 242).

9.Slide the SAS drives and fillers approximately two inches out of the drive bays. See “Removing a Hot-Pluggable Disk Drive” (page 188).

CAUTION: When disconnecting the SAS cables, note the labeling on the cables. Both cables and sockets are clearly marked with the correct channel.When reconnecting these cables, you must match each cable with the appropriate socket on the SAS core I/O card. If the cables are mismatched, the server operating system may not reboot.

10.Disconnect the SAS data and power cables from the connectors on the SAS backplane (Figure 6-34).
