Slots 1 and 2 are dedicated for the PCI-X core I/O cards. The LAN core I/O card is installed either in slot 2 or slot 10 depending on the configuration. PCIe SAS core I/O cards are installed in slots 3 or 4 on the PCIe I/O backplane.

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 SAS Core I/O Card

NOTE: You may need to remove the LAN core I/O card to access the SAS core I/O card.

To remove the SAS 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.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).

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, 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.

4.Disconnect the internal SAS cables attached to the card.

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.SAS RAID card only, pull the gate latch toward the front of the chassis to unlock the SAS core I/O card.

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

Replacing the SAS Core I/O Card

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

1.Insert the replacement card into the dedicated SAS core I/O card 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.SAS RAID card only, close the gate latch to secure the end of the SAS RAID card.

3.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.
