and iLO 2 MP status LEDs. For more detail on the port locations and LEDs, see “Controls, Ports, and LEDs” (page 36).

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: The dedicated core I/O board slot is not hot-pluggable.

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 Core I/O Board

IMPORTANT: The replacement core I/O board may not be the same as the current core I/O board. If the server is running an operating system other than Windows or Linux, the current core I/O board may not have a VGA connector. The replacement core I/O board always ships with a VGA connector. The VGA connector may not be functional depending on the server operating system. However, when you run system discovery utilities, such as MAPPER, the output includes VGA.

To remove the core I/O board, 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 board.

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.Disconnect the internal USB cable attached to the core I/O board.

6.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.

CAUTION: Do not rock the board side to side during removal, or you can damage the slot pins. Pull the board straight up and out of the chassis for removal.

7.Grasp both edges of the board and apply even force to lift the board straight up and out of the chassis.

Replacing the Core I/O Board

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

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

CAUTION: Do not rock the board side to side during installation, or you can damage the slot pins. Push the board straight down into the slot for installation.

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.
