Connecting the cables
The cable connections required depend on whether you are using a keyboard and mouse or wired
(Ethernet) or wireless connection.
1. Place the all-in-one in a convenient, well-ventilated location.
2. Remove the rear I/O cover from the all-in-one.
3. If you want to use a wired network connection, connect an Ethernet cable to the Ethernet port on
the rear panel of the all-in-one (1), and then to an active Ethernet jack (2).
For more information, see Connecting to wired networks on page 17 .
