Overview

The PA-E3 is used on the VIP2 in Cisco 7000 series and Cisco 7500 series routers and can be installed in either port adapter slot 0 or slot 1 on the VIP2 motherboard.

Note You can have up to three E3 serial interfaces on a VIP2 motherboard. Cisco recommends a configuration of one PA-E3 (with one E3 serial interface) and one PA-2E3 (with two serial interfaces) for a total of three E3 serial interfaces per VIP2.

Figure 3-1 shows two one-port PA-E3 port adapters installed in port adapter slot 0 and slot 1, on a VIP2-15 or VIP2-40.
