Ports 1-12
These twelve LAN (Local Area Network) ports con-
nect network devices, such as PCs, print servers,
network attached storage, and remote hard drives at
10/100/1000Mbps. Or, they can be used to expand
your network by connecting to a 1000Mbps hub or
switch. When connecting to a PC equipped with an
Instant Gigabit Network Adapter, just plug one end
of a Category 5e Ethernet network cable into the RJ-
45 port on the Adapter and the other end into one of
the ports on the Gigabit Ethernet Switch.
