Universal Serial Bus connectors

Your server has three Universal Serial Bus (USB) connectors, which are configured
automatically. USB is a serial interface standard for telephony and multimedia
devices. It uses Plug and Play technology to determine the type of device attached
to the connector.

USB cables and hubs

You need a 4-pin cable to connect devices to USB 1, USB 2, and USB 3. If you
plan to attach more than three 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 up to 12 Mbps speed with a maximum of 127 external
devices and a maximum signal distance of 5 meters (16 ft) per segment.

USB-port connectors

There are two USB-port connectors on the rear of the server and one USB-port
connector on the front. These USB-port connectors are used to attach USB
compatible devices to the server.
The following illustration shows the pin-number assignments for the USB-port
connectors on your server.
