Replacing the Riser Card
There are two riser cards available from HP for this product. One has two PCI slots and the other has
two PCI Express x1 slots. Both cards have a slot designated for the Powered Serial Port expansion
card. You can purchase either card as a replacement from HP.
To replace the riser card:
1.
Remove/disengage any security devices that prohibit opening the computer.
2.
Remove all removable media, such as compact discs or USB flash drives, 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.
6.
Remove the computer access panel.
7.
Rotate the power supply all the way back to access the full-height expansion card retention
latch.
NOTE:
If you are using a PS/2 mouse and/or PS/2 keyboard, make sure they are unplugged
from the rear of the computer so that the connectors do not block the power supply from rotating
all the way back.
