Overview
The PA-E3 is used on the Catalyst RSM/VIP2 in the Catalyst 5000 family switches and can be
installed in either port adapter slot 0 or slot 1 on the Catalyst RSM/VIP2 motherboard.
Note You can have up to three E3 serial interfaces on a Catalyst RSM/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.
Figure 4-1 shows two one-port PA-E3 port adapters installed in port adapter slot 0 and slot 1, on a
Catalyst RSM/VIP2-40.
