You can connect various external devices, such as a mouse and printer, to the I/O
ports and connectors on the systems back panel. The system BIOS detects the pres-
ence of external devices when you boot or reboot your system. When connecting
external devices to your system, follow these guidelines:
Check the documentation that accompanied the device for specific installation
and configuration instructions.
For example, most devices must be connected to a particular I/O port or connec-
tor to operate properly. Also, external devices like a mouse or printer usually
require you to load software files called
device drivers
into memory before they will
work. These software drivers help the system recognize an external device and direct
its operation. Device drivers of this type are normally included with your operating sys-
tem software.
Always attach external devices
while your system is
turned off
. Then turn on any
external devices
before
turning on the system unless the documentation for the device
specifies otherwise. (If the system does not seem to recognize the device, try turning
on the system before turning on the device.)
For information about enabling, disabling, or configuring I/O ports and connectors, see
Chapter 4, Using the System Setup Program, or Chapter 5, Using the Resource
Configuration Utility. For detailed descriptions and illustrations of each port and con-
nector on the I/O panel, see Appendix B, I/O Ports and Connectors.

A keylock behind the lock access panel on the front bezel prevents unauthorized
access to the hot-pluggable hard-disk drives, CD-ROM drive, diskette drive, and the
power switch, all of which are behind the bezel. A second lock on top of the unit pre-
vents the top cover from being opened and the fans from being removed.
The PowerEdge 4350 system also includes a system intrusion switch that signals
appropriate server management software if the top cover is opened.
