Switch Interfaces
This section provides pin assignments for the asynchronous console ports,
RJ-45 switch ports, and the Redundant Power Supply (RPS) connector.
If you have installed a Port Interface Card (PIC), pin assignments for these can
be found in the
Port Interface Card Hardware Reference
(which is included on the
Documentation and Tools CD-ROM bundled with your switch, or can be
downloaded from
www.alliedtelesis.com/support/software
).
Asynchronous Console Port
All Rapier switches except the Rapier 48w have a single asynchronous serial
RS-232 console port, labelled “RS-232 Terminal Port /asyn0”. The Rapier 48w
switch has two asynchronous serial RS-232 console ports, labelled “asyn0” and
“asyn1”.
The RS-232 console ports are used to connect the switch to a management
device. For management purposes the switch’s software can be accessed from a
terminal, a PC running terminal emulation software, or from a remote location
via a modem connection. You can also use the RS-232 console ports to establish
a network connection from a remote site using SLIP and a modem.
The console ports have a DCE female connector. This allows the use of a
straight-through cable when connecting the switch to a terminal or PC. Output
from the
show asyn
command will, however, still have a DTE perspective. The
internal DTE pin roles are listed in
Table 3
.

“Terminal and Modem Cables” on page 29

connection options for the RS-232 console ports.
