PA-E3 Serial Port Adapter Installation and Configuration

Chapter 1 Overview
Identifying Interface Addresses
Catalyst RSM/VIP2 Interface Addresses
In Catalyst 5000 family switches, the Catalyst RSM/VIP2 can be installed in any slot except the top slots,
which contain the supervisor engine modules. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch
does not use interface processor slot numbering; therefore, the slots in which it is installed are not
numbered. A port adapter can be installed into either port adapter slot 0 or slot 1 on a Catalyst
RSM/VIP2. See
The interface address is composed of a two-part number in the format
port-adapter-slot number/interface-port number. See
. For example, if a single-port PA-E3 is
installed in port adapter slot 1 of a Catalyst RSM/VIP2 in a Catalyst 5000 family switch, the interface
address would be 1/0. If a dual-port PA-2E3 is installed in port adapter slot 1 of a Catalyst RSM/VIP2
in a Catalyst 5000 family switch, the interface addresses would be 1/0 and 1/1.

1.
Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.
2.
Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
3.
Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
