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.
