HP Model 748 Installing the A4505A PCI Module Upgrade - Page 4

Procedure If you need keyboard and mouse support, you need a Hewlett-Packard P/S2 compatible keyboard and mouse to connect to the P/S2 connectors on the VMEbus board computer. WARNING: CAUTION: Procedure 1 Stop any application programs, then shut down your workstation. 2 Turn the workstation off, and unplug the power cord(s). To avoid electrical shock, make sure you unplug the power cable from the wall outlet and the system unit before proceeding any further. The internal components of your workstation are susceptible to mechanical and electrostatic shock. To prevent such damage from occurring, observe the following precautions during the installation procedure. • Stand on a static-free mat • Wear a static-grounding wrist strap to ensure that any accumulated electrostatic charge discharges from your body to ground. Attach the static-grounding wrist strap by following the instructions on the package that contains the strap. Be sure to attach one end of the strap to the system chassis. • Handle workstation and upgrade kit components carefully to prevent damage from mechanical shock. 3 Using a flat-tipped screwdriver, unscrew the captive screws inside the EISA module handles five to seven turns (until each screw pops out). 4 Grasp the EISA module handles and pull the EISA module out of the chassis, as shown in Figure 1. 4
