Table 2-18 shows the

pinout of the AUI

(attachment unit

interface) port. The

form factor is female

DB-15.

Indicators

The Ethernet LED indicators

are located to the right of the

Ethernet connector. Table 2-19

shows how to interpret them.

Ports 1, 2,

3, and 4

Ports 1 through 4 are

software-

configurable serial

ports for V.35 or

RS-232 interface types

and DTE or DCE

termination. This

allows for greater

flexibility in

connections with a

wide variety of

configurations. The

default for Port 1 is

Frame Relay V.35

DTE; Port 2 is Frame

Relay RS-232 DTE;

Port 3 is Poll/Select

Host RS-232 DCE;

and Port 4 has no

default. The form factor of the connector is female DB-25. Table 2-20 shows the

pinout of these ports.
