Switch Interfaces
This section provides pin assignments for the switch’s RS-232 Terminal Port
and RJ-45 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 from www.alliedtelesis.com/support/software).
RS-232 Terminal Port
The RS-232 Terminal Port is 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 Terminal Port to establish
a network connection from a remote site using SLIP and a modem.
The switch’s RS-232 Terminal Port has a DCE female socket. 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.
See Terminal and Modem Cables on page 20 for more information on
connection options for the RS-232 Terminal Port.
