The functional check consists of checking the 1264C power supply
voltages to the VXIbus limits at the P1 and P2 connectors using a
digital voltmeter.
Referring to Tables 3-2 to 3-5 and Figure 3-1 connect one lead of
the voltmeter to a supply pin. Connect the reference lead of the
voltmeter to one of the ground pins.

If the voltages are within the specified ranges, the mainframe
complies with the VXI voltage limit specifications.
Note that the "Voltage Range" values in Table 3-5 are identical to
the VXIbus Specification. The voltage range limits provided in
Table 3-1 refer to the voltage monitor indicators on the 1264C front
panel. The monitor will detect a voltage error when the limit is
exceeded (V
