Power Requirements Hardware Preparation and Installation

2.5.2Power 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.

Table 2-3 Baseboard and RTM Power Requirements

Board ID	+3.3 V		+5 V	+12 V
CPCI-6020-500	2.6	A typ	2.8 A typ.	15 mA typ.
	3.5 A max		3.75 A max.	20 mA max.
CPCI-6020-MCPTM-01	0.0	A typ.	50 mA typ	0.0	A typ.
	0.0 A max.		100 mA max.	0.0	A max.

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.

2.5.3Thermal Requirements

The CPCI-6020 module requires a minimum air flow of 250 LFM when operating at a 55°C (131°F) ambient temperature.

Most of the heat is generated by CPU at the top layer. Make sure that there is sufficient airflow to the CPU heatsink.

2.6Hardware 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.
