￿interface cards

Using redundant switching cards and redundant power supplies.

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.

The CoreBuilder 7000 family power supplies are shown in Table 7-1.
