by preventing inadvertent contact between cards during the replacement, addition, or removal of a card.

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.

Removing a PCI/PCI-X/PCIe Card Divider

To remove a PCI/PCI-X/PCIe card divider, 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 extracting the card divider, ensure you release the locking tabs completely or you can damage them. If you damage the tabs, the divider does not seat properly when you reinsert it.

4.Use a tool to carefully push the two tabs that attach the card divider to the I/O board assembly.

5.Pull the card divider up sharply by the handle to disengage it from the I/O board assembly (Figure 6-9).
