Serial Access to the SMC Switch
Use of a serial interface to the switch should only be needed if the factory assigned IP address for
the switch has been somehow deleted, altered or corrupted. Otherwise, use of the web or telnet
access procedure is recommended. To use a serial interface with the switch, connect a laptop, or
PC to the switch’s console port. Refer to
Figure 1-9 for the location of the console port and use the
steps that follow for access.

1. Establish a command line interface (CLI) and list the port connection settings:
Port Settings
Bits Per Second=19200
Data bits=8
Parity=None
Stop Bits=1
Flow Control=none
2. In order to verify and save any new settings type the following:
console# show running-config (make sure your settings are intact)
console# copy running-config startup-config (it will ask for a file name)
console# file name? startup
Note: Any changes made to the switch port settings through the serial interface or Web
interface are not saved unless the previous steps have been executed.
3. Power cycle the switch by disconnecting and reconnecting its power cable.
