Overview

and can be installed in either port adapter slot 0 or slot 1 on the VIP2 motherboard.

Note You can have up to three T3 serial interfaces on a VIP2 motherboard. Cisco recommends a

conﬁguration of one PA-T3 serial port adapter (with one T3 serial interface) and one PA-2T3 serial

port adapter (with two serial interfaces) for a total of three T3 serial interfaces per VIP2.
