The CoreBuilder 7000 family supports three kinds of power supplies: an
AC unit rated at 90A, and two DC units rated at 90A and 40A. You can
use each one of them in any CoreBuilder 7000 family ATM switch. The
power supply supports two output channels: one 5V DC channel which
supplies the CoreBuilder switch and the interfaces cards, and one 12V DC
channel which supplies the fans.
