Overview

The PA-T3 serial port adapter is used on the Catalyst RSM/VIP2 in the Catalyst 5000 series 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 T3 serial interfaces on a Catalyst RSM/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 Catalyst RSM/VIP2.

Figure 4-1 shows two one-port PA-T3 serial port adapters installed in port adapter slot 0 and slot 1 on a Catalyst RSM/VIP2-15 or Catalyst RSM/VIP2-40.
