Serial-port connector
Your appliance server has one serial-port connector located on the rear of the
appliance server.
The following table and illustration shows the pin-number assignments for the 9-pin,
male D-shell serial-port connector on the rear of your appliance server. These pin-
number assignments conform to the industry standard.
Universal Serial Bus ports
Your appliance server has two Universal Serial Bus (USB) ports, which configure
