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 78 for their location. 1 5 6 9 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 78. Important To operate the computer within FCC Class A or Class B limits, use a category 5 Ethernet cable. Universal Serial Bus connectors Your computer has two Universal Serial Bus (USB) connectors for optional telephony and multimedia devices. USB devices configure automatically with Plug and Play technology. Notes: 1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB connectors and devices will be disabled during the power-on self-test. 2. If you install a USB keyboard that has a mouse connector, the USB keyboard emulates a mouse, and you will not be able to disable the mouse settings in the IBM Setup Utility program. USB cables: Use a 4-pin USB cable to connect external devices to USB connectors. USB technology transfers data at up to 12 megabits per second (Mbps) with a maximum of 127 external devices and a maximum signal distance of 5 meters (16 ft) per segment. 80 IBM IntelliStation E Pro Types 6204 and 6214: User's Guide
