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.
