Replacing an Expansion Card Bracket

The computer supports one full-height, half-length PCI expansion slot or one half-height, half-length PCI Express x16 expansion slot. The computer ships with a PCI Express bracket. An optional PCI Express expansion card bracket assembly with riser card or PCI expansion card bracket assembly with riser card can be obtained from HP or an authorized provider.

A variety of optional PCI cards are available including:

Wireless LAN card

FireWire card

Modem card

NIC card

Graphics card

NOTE Adding a graphics card will, by default, disable the integrated graphics on the system board. The integrated graphics can be reenabled by changing the BIOS settings in Computer Setup.

A USDT serial/parallel I/O assembly, available as an option, replaces the expansion slot cover and connects directly to the system board.

To remove the expansion card bracket that ships with the computer:

1.Remove/disengage any security devices that prohibit opening the computer.

2.Remove all removable media, such as diskettes or compact discs, from the computer.

3.Turn off the computer properly through the operating system, then turn off any external devices.

4.Disconnect the power cord from the power outlet and disconnect any external devices.

CAUTION Regardless of the power-on state, voltage is always present on the system board as long as the system is plugged into an active AC outlet. You must disconnect the power cord to avoid damage to the internal components of the computer.

5.If the computer is on a stand, remove the computer from the stand and lay the computer down.

6.Remove the computer access panel.

CAUTION After opening the computer cover, look for the LED on the system board between the DIMM sockets. If the LED is illuminated, the system still has power. Turn off the computer and remove the power cord before proceeding.
