HP RP5 5810 manual Installing a 12-Volt Powered USB Expansion Card

NOTE: The following sections provide instructions for installing a Powered USB expansion card. However, the procedure is basically the same for installing any PCI Express expansion card into a PCI Express x16 expansion slot.

Installing a 12-Volt Powered USB Expansion Card

The computer is equipped with a 24-volt Powered USB connector on the riser card, and may have one or two 12-volt Powered USB half-height expansion cards installed for a total of 6 optional 12-volt Powered USB ports. The 24-volt Powered USB connector and the 12-volt Powered USB connector are keyed differently as a precaution to prevent connection errors.

To install a half-height 12-volt Powered USB expansion card:

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

2.Remove all removable media, such as optical 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.Locate the correct vacant expansion socket on the system board and the corresponding expansion slot on the back of the computer chassis.

NOTE: You can install the Powered USB expansion card in either the PCI Express x16 slot or the PCI Express x16 slot that is downshifted to a x4 slot, or both. Two 12-volt Powered USB expansion cards are supported.
