Universal Serial Bus ports
The Universal Serial Bus (USB) ports allow you to add new plug and
play serial devices without opening up the system. You simply plug
the devices into the ports. The USB determines system resources for
each peripheral and assigns them without user intervention. Up to 127
devices can be daisy chained to the USB ports.
!
Fax/modem ports
Some systems come with a 56-kilobytes per second (Kbps)
fax/modem board. The fax/modem board allows the connection of a
phone line to the computer for fax and data communications functions.
Dual fax/modem ports let you use a telephone line for the fax/modem
and your telephone.

LAN connector
The rear panel on minitower models contains one RJ-45-compatible
port for connecting the system to an Ethernet local-area network
(LAN). Desktop models have a network board installed in a PCI slot.

SCSI port
Some systems come with a SCSI adapter board in an expansion slot
on the rear panel. An Ultra-Wide SCSI interface on the board allows
connection of up to 15 SCSI devices to the board.
