4.Reconnect the internal SAS cables to the card.

CAUTION: When reconnecting the SAS cables, note the labeling on the channel cables. Both cables and sockets are clearly marked with the correct channel. 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.

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

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

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

Removing and Replacing the LAN Core I/O Card

The LAN core I/O card enables network connectivity for the server. The dedicated slot for the LAN core I/O card is slot 2 unless there are two PCI-X SAS core I/O cards installed. In this case, the dedicated slot for the LAN core I/O card is slot 10.

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: PCI/PCI-X slots 1 and 2 are dedicated for use by core I/O cards. Do not place any other PCI/PCI-X expansion cards in slots 1 and 2. Slots 1 and 2 are not hot-plug capable.

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

Removing the LAN Core I/O Card

To remove the LAN core I/O card, follow these steps:

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

2.Disconnect all external cables attached to the card.

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

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

5.Remove the slotted T15 screw that attaches the card bulkhead to the chassis; use a T15 driver to turn the screw counterclockwise until it is free from the chassis.

6.Grasp the card by the edges and lift it out of the chassis.

Replacing the LAN Core I/O Card

To replace the LAN core I/O card, follow these steps:

1.Insert the replacement card into the dedicated LAN core I/O slot.

a.Insert the tab at the base of the card bulkhead into the slot in the chassis.

b.Align the card connectors with the slots on the I/O board.

c.Apply firm, even pressure to both sides of the card until it fully seats into the slot.

2.Replace the slotted T15 screw that attaches the card bulkhead to the chassis; use a T15 driver to turn the screw clockwise until it tightens to the chassis.
