RPM Port Numbering
This section describes how RPM ports are numbered so that when you configure the RPM you can correctly identify the interfaces.
The port-numbering scheme on the RPM is as follows:
LAN interfaces are identified as chassis-slot/slot/port.
The top-rear interface card is slot 1.
The bottom-rear interface card is slot 2.
Ports are numbered 1 to 4 from top to bottom.
The ATM cell bus interface is always port 1.
