Serial-port connector: The following table shows the pin-number assignments for
the 9-pin, male D-shell serial-port connector on the rear of the server. These pin-
number assignments conform to the industry standard.
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 up to 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.
