Universal Serial Bus connectors

Your server has two 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 that is

USB technology transfers data at up to 12 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 located on the rear of the server for attaching USB-
compatible devices. See "I/O connector locations" on page 51 for the location of the
USB connectors. The following table shows the pin-number assignments for the USB
connectors.

Audio connectors
