Caution To prevent damage to the VXI instruments, install the instruments when the mainframe is turned off.

A.Install the HP E1403 A/B-size Module Carrier or the HP E1407 A/B-size Module Carrier into the mainframe. This is done by aligning the top and bottom of the carrier with the card guides and slowly pushing the carrier into the mainframe. The front of the carrier should be even with the front edges of the mainframe.

B.Slide the A- or B-size instrument into the carrier until it connects.

C.Tighten the retaining screws on the top and bottom of the instrument.

WARNING All instruments within the VXI mainframe are grounded through the mainframe chassis. During installation, tighten the instruments’ retaining screws to secure the instrument to the mainframe and to make the ground connection.

Step 4: Installing The software required to use the IEEE 1394 interface in a VXI system,

the HP I_O Libraries including the Adaptec® host adapter drivers, is contained on the HP I_O Libraries CD.

Note Refer to Chapter 4: IEEE 1394 Fundamentals and Interface Overview for

more information on the HP I_O Libraries and related software.

A.Turn on the PC if you have not already done so. Close all open applications and insert the I_O libraries CD into your PC CD-ROM drive. Inserting the CD automatically activates the installer. If the installer is not activated, select Start / Run and type <drive>:SETUP.EXE. Do not turn on the VXI mainframe.

Note If your PC indicates that new hardware has been found, select “do not

install a driver.” The Adaptec ® host adapter drivers are installed with the I_O libraries installer program.

B.Review the information and license agreements presented at the beginning of the installation process.

C.Continue through the installation process as directed by the installer. Be sure to indicate that you want HP I_O Libraries support for the E8491A interface installed by clicking on the box next to “Install HP E8491 VXI Components.” Do not configure the interface at this time.
