The Ethernet controller is integrated on the system board. You do not need to set
any jumpers or configure the controller for your operating system before you use
the Ethernet controller. However, you must install a device driver to enable your
operating system to address the Ethernet controller. The device drivers are
provided on the preloaded software and the Device Drivers and IBM Enhanced
Diagnostics CD.
Ethernet connector
There is an RJ-45 connector on the rear of the computer, see "I/O connector/port
locations - Type 6846 and 6836" on page 30 for the location of this connector.
Universal Serial Bus connectors
Your computer has two Universal Serial Bus (USB) connectors, which are
configured automatically. USB is an serial interface standard for telephony and
multimedia devices. It uses Plug and Play technology to determine the type of
device that is attached to the connector.
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
Configuration/Setup Utility program.
USB cables and hubs
You need a 4-pin cable to connect devices to USB 2 or USB 3. If you plan to attach
more than two USB devices, you must use a hub to connect the devices. The hub
provides multiple connectors for attaching additional external USB devices.
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 five meters
(16 ft.) per segment.
USB connectors
There are two USB connectors on the rear of the computer for attaching USB
compatible devices, see "I/O connector/port locations - Type 6846 and 6836" on
page 30 for the location of the USB connectors.
Audio connectors
The audio connectors are used to connect external audio equipment to your
computer, see "I/O connector/port locations - Type 6846 and 6836" on page 30 for
