Figure 75: Ethernet Cable Connector
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.

with your switch.

adapter appropriate for your modem.
