NOTE: If your laptop or PC does not have a DB-9 male connector pin and you
want to connect your laptop or PC directly to the switch, use a combination
of the RJ-45 to DB-9 female adapter supplied with the switch and a USB to
DB-9 male adapter. You must provide the USB to DB-9 male adapter.
NOTE: Most modems have an RS-232 DB-25 connector. You must separately
purchase an adapter to connect your modem to the RJ-45 to DB-9 adapter
and Ethernet cable supplied with the switch.
To connect a modem to the console port:
1. Turn off power to the switch.
2. Turn off power to the modem.
3. Connect one end of the cable to the console port (labeled CON or CONSOLE ) on the
switch.
