Mechanical Information
Model 748 Chassis and Modules
Mounting and Support
Each Model 748 workstation is shipped with a rack mount kit including flanges, spacers, and
screws. In this section, the term "back" refers to the cable-out side of the workstation. Model
748 satisfies three rack mount orientations:
• Mast mount
• Rack mount, either front out or back out
Power switching is accessible from both front and back. A single power LED is on the front.
Status and test LEDs are located on the Model 743 Model 744 VME Board Computers. If the
power supply and VME board computer LEDs must be visible, mount the workstation back
out. Devices within the mass storage module can be arranged for front or back accessibility.
• Wall mount
PCI/EISA and VME card cages are fixed and cannot be reversed.
Mechanical Drawings
For OEMs that have signed a Hewlett-Packard non-disclosure agreement, the mechanical
drawings are available by request from the Workstation Systems Group through your
Hewlett-Packard OEM Sales Representative. These drawings are Hewlett-Packard confiden-
tial and cannot be redistributed.
When you ask for drawings, please specify the following:
• Drawing part number, size, and page number, if needed
• Name, assembly or subassembly
The drawings are sent to your Sales and Service Office.
Conversion Cables
All conversion cables are 762 plus or minus 30 mm (30 plus or minus 1.18 inch) long. The
end of the cable that connects to the board computer uses a micro D-sub male (MDSM) con-
nector. The other end of the cable uses a standard D-sub or other connector.
