Wired connections
Connecting to a local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the computer.
To connect the network cable:
1. Plug the network cable into the network jack (1) on the computer.
2. Plug the other end of the cable into a network wall jack (2).
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a modem
or telephone cable into the RJ-45 (network) jack.
Using the modem (select models only)
The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable (included
with select models only). In some countries or regions, a country- or region-specific modem cable
adapter (included with select models only) is also required. Jacks for digital PBX systems may resemble
analog telephone jacks, but they are not compatible with the modem.
WARNING! Connecting the internal analog modem to a digital line can permanently damage the
modem. Immediately disconnect the modem cable if you accidentally connect it to a digital line.
