The following table provides power consumption information based on one memory size. Each
Gigabit Ethernet channel will add up to 1.25 watts to the power envelope when connected and
active.
6.4
Start-Up Current of the VMP3
During the startup process, clamping and leakage effects result in a much higher “inrush cur-
rent” than the current required for normal operation. For this reason power supplies used with
the VMP3 must be able to provide 7 A during the first 10 ms of operation.

Note...
If less power consumption is required, it is possible to disable features
of the CPU such as TSEC controllers, PCI, Security Engine, etc. which
are not being used. For further assistance, contact technical Support at
