Universal Serial Bus ports
Your server has two Universal Serial Bus (USB) ports,
which configure automatically. USB is an emerging serial
interface standard for telephony and multimedia devices. It
uses Plug and Play technology to determine the type of
device attached to the connector.
Notes:
1. If you attach a standard (non-USB) keyboard to the
keyboard connector, the USB ports and devices will be
disabled during the power-on self-test (POST).
2. If you install a USB keyboard that has a mouse port,
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 1 or
USB 2. 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 provides 12 megabits-per-second (Mbps)
speed with a maximum of 127 external devices and a
maximum signal distance of five meters (16 ft.) per
segment.
USB-port connectors
Each USB port has an external connector on the rear of
the server for attaching USB compatible devices.
The following table shows the pin-number assignments for
the USB-port connectors on the rear of your server.
