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.
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 DB9 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 on page 14.
See Terminal and Modem Cables on page 20 for more information on
connection options for the RS-232 Terminal Port.

Switch RJ-45 Ports
Caution. Do not plug a phone jack into any RJ-45 port. Doing so could damage
the switch. Use only twisted pair cables with RJ-45 connectors.
