RS-232 Terminal Port (ASYN0)
The RS-232 ASYN0 terminal port is used to connect the switch to a
management device for initial configuration and switch management tasks.
This allows the switch software to be accessed from a terminal, a PC running
terminal emulation software, or from a remote location via a modem
connection. You can also use ASYN0 to establish a network connection from a
remote site using SLIP and a modem.
ASYN0 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 DTE pin layout
is shown in the following figure and table.
