Some of the components used in this product are susceptible to damage by static
discharge. Refer to the Safety Considerations information at the front of this
manual before handling the card.
Current Requirements
The LANIC circuit card obtains its operating voltages from the host computer.
The current requirements of the card are listed in the power requirements entry
of Table 1-3.
All HP 3000 Computer systems can supply adequate current to accommodate the
LANIC card without the need for any power supply modification. However, it
is possible that the + 12V supply in the HP 3000 system may be set to a low
voltage such that the VP lead on the AUI cable may not provide the minimum
voltage specified by IEEE 802.3 (+11.28V). If MAD replacement does not correct
an apparent MAD problem. the VP voltage should be checked. This is done by
connecting an accurate voltmeter between the +12 and GND test points near the
LEOs on the LANIC card. This must be done when the MAU is connected to
the LANIC and MAD power is on (as indicated by the VP LED). MAU power
can be turned on by executing the LANIC self test. Consult the appropriate
HP 3000 CE handbook for instructions on adjusting the +12V power on the
particular system involved.
