VXI instruments are cooled by air drawn through the back of the mainframe
and exhausted out the sides. The power supply is cooled by air drawn from
the right side (facing the mainframe) and exhaused out the left side. When
placing the mainframe on a work bench or if the mainframe is rack mounted,
provide at least a one inch clearance at the back and sides to allow for proper
air flow.
The HP E8400A mainframe has 13 slots labeled 0 through 12. Any VXI
instrument can be installed in any slot; however, slot 0 is reserved for
devices capable of providing the system's slot 0 functionality. This
functionality includes:
•
locating instruments installed in the mainframe
•
managing (arbitrating) data flow across the backplane
•
providing the system clock (SYSCLK - 16 MHz)
Examples of these devices are the HP E1406 Command Module and
embedded controllers such as the HP E6232/E6233 VXI Pentium PCs, the
HP RADEPC7B PC, and the HP E1497/E1498 V743 controllers.
Multiple instruments which combine to create a virtual instrument (e.g. a
scanning multimeter), and instruments which access the backplane local bus
should be installed in adjacent slots.
Note
Hewlett-Packard VXI Installation Consultant (HP VIC) is an
excellent tool for installing and configuring VXI systems. The
program guides you through hardware installation, driver
installation, and system self-test. HP VIC is available on the World
Wide Web starting at http://www.hp.com/go/inst_drivers.
Figure 1-4 shows the installation of C-Size instruments.
