Ports

This section explains pin assignments for the following:

■ RS-232 Terminal Port (ASYN0)

■ RJ-45 Ports

RS-232 Terminal Port (ASYN0)

The RS-232 ASYN0 port connects the switch to a management device for initial

configuration. This port allows the software on the switch to be accessed from a

terminal or a PC running terminal emulation software.

The ASYN0 port has an RJ-45 socket with an industry recognised pinout. This

requires using a straight-through RJ-45 cable with an RJ-45 DB9 connector

when the switch is connected to a terminal or PC. The socket is wired as a DTE

and the pin layout is shown in the following figure and table.

See “Terminal and Modem Cables” on page 19 for more information on

connection options for the RS-232 terminal port.
