Using Other Power Supplies

48 Using the HP E1399A
You can use any of the other power supply voltages from a standard
VXIbus backplane as described in the VXIbus Specification. All of the
available voltages have been stubbed onto the breadboard module as user
access points. Just remember that you must provide your own fusing and
filtering on board the module for each power supply you access from the
backplane.
You must also provide adequate cooling for dissipation of the heat
generated by the power requirements of your customs circuitry. See
"Cooling Requirements" in Chapter 2 for more information on establishing
cooling specifications for your module. Recommended power supply
voltage applications are listed in Table 3-5.
Table 3 5. Power Supply Voltage Applications
