Serial connectors
Your computer has two standard 9-pin D-shell serial connectors: Serial connector 1
and Serial connector 2. See “Input/output connectors” on page 75 for their location.
Ethernet connector
Your computer comes with an integrated Ethernet controller. This controller provides
an interface for connecting to 10-Mbps or 100-Mbps networks and provides full-
duplex capability, which enables simultaneous transmission and reception of data on
an Ethernet local area network (LAN).
To access the Ethernet connector, attach a Category 3, 4, or 5 unshielded twisted-pair
(UTP) cable to the RJ-45 connector on the rear of your computer, see “Input/output
connectors” on page 75.
