The circuitry in the HP VXI Pentium Controller can be damaged
by electrostatic discharge. All work must be done by a trained
technician at a static-free workstation.
You will need the following tools to access the controller's main circuit
board and install the pin jumpers:
•
two, 2-position, 2.5 mm, removable jumpers;
•
a grounding wrist strap and static-free workstation; and
•
a #0 (small) Phillips screwdriver.
1. At a static-free workstation, place the HP VXI Pentium Controller on
its left side such that the front panel is facing you and the sheet-metal
cover with its bar-coded serial number is on the far edge away from
you.
2. Attach the grounding strap to your wrist and take appropriate
anti-static precautions during the rest of this procedure.
3. With the #0 Phillips screwdriver, remove the eight Phillips-head
screws holding the sheet-metal cover to the chassis. Do not lose these
very small screws. They will be needed to re-attach the cover.
4. Remove the sheet-metal cover and set it aside.
The two jumper-pin connector blocks, labelled P7 and P8, are located
just to the left of the power cable connector (see the multi-colored wire
harness) on the main I/O base board near the rear-center of the unit.
5. Place a jumper to connect pin 7 to pin 8 on jumper block P7 and a
jumper to connect pin 1 to pin 3 on jumper block P8 as shown below:
Figure D-1. Jumper-Pin Connector Blocks
6. Replace the sheet-metal cover such that the bent edges on the sides
are down and the bar-coded serial number label is on the edge nearest
the VXI connector blocks on the rear of the unit.
