•
Dimensions 160.93 mm x 233.35 mm without front panel
•
Weight:
max 1000 g

Power Consumption
The table below helps customers calculate the power consumption of each VP7 system. For
measurement, the VP7 is mounted on a VME backplane, without keyboard and hard disk. The operating
system (MSDOS) comes up from floppy disk. During measurement, the power consumption of the
backplane and the floppy drive can be ignored.
Typical Current in A (+5V )

Fused VCC (+5V)
The following connectors provide a fused VCC voltage (+5V):
P1700(USB), P2000(KBD), P2001(Mouse), P2100(LPT1), P2600(LPT2), P2302(COM2),
P4200(VGA), P2700(COM3), P2701(COM4)
The total current drawn from this VCC voltage may not exceed 1.5 Amperes.
The methods for measurements are defined as follows:
DOS prompt with power management :
BOOT disk with DOS 6.22
config.sys: device=power.exe adv, no autoexec.bat
wait until CPU enters HLT state
measure current on DOS prompt
DOS prompt without power management:
BOOT disk with DOS 6.22
config.sys: device=power.exe off, no autoexec.bat
measure current on DOS prompt
