Power Requirements
The CPCI-6020 module draws  +3.3VDC, +5VDC, VIO, +12VDC and -12VDC, with a voltage 
variation of -/+ 5% from the standard value, from the CompactPCI backplane connector J1. 
Typical power consumption of only the CPCI-6020 is approximately 15 W at +5VDC and 9 W at 
+ 3.3VDC.
The CPCI-6020 supplies +3.3VDC, +5.0VDC, +12VDC and -12VDC to J3 and J5 for use by the 
transition module. Separately fused +5VDC is also provided for the keyboard/mouse. Separate 
+5VDC fused power is also provided for each USB channel and the PMC slot +5VDC.
No more than 0.5 of an amp is allowed per power pin (IEEE 1386.1 specification) on any power 
connector.
2.5.3
Thermal Requirements
The CPCI-6020 module requires a minimum air flow of 250 LFM when operating at a 55
°
(131
°
F) ambient temperature.

Hardware Configuration
To produce the desired configuration and ensure proper operation of the CPCI-6020, you may 
need to carry out certain hardware modifications before installing the module.S ome hardware 
modifications are controlled through manual installation or removal of header jumpers or 
interface modules on the baseboard or the associated transition module. These modifications 
are described in the next section.
