Dell PowerEdge 4400 - Manual (Page 36)

Connecting External Devices
You can connect various external devices, such as a mouse and printer, to the I/O ports and connectors on the computer ’s back panel (see Figure
3).
Figure 3. Back-Panel Features
The system BIOS detects the presence of external devices when you boot or reboot your system. When you connect external devices to your
computer, follow these guidelines:
l 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 connector to operate properly. Also, external devices such as
a mouse or printer usually require that you load software files called device drivers into memory before they will work. These software
drivers help the computer recognize an external device and direct its operation. Device drivers of this type are normally included with
your operating system software.
l Always attach external devices while your computer is turned off. Then turn on any external devices before turning on the computer unless the
documentation for the device specifies otherwise. (If the computer does not seem to recognize the device, try turning on the computer before
turning on the device.)
For information about enabling, disabling, or configuring I/O ports and connectors, see " Using the System Setup Program " or " Using the Resource
Configuration Utility ." For detailed descriptions and illustrations of each port and connector on the I/O panel, see " I/O Ports and Connectors ."
Preventing Unauthorized Access Inside the Computer
A keylock behind the door on the front bezel prevents unauthorized access to the hot-pluggable hard-disk drives. A second lock on the back of the
unit prevents the top cover from being removed.
PowerEdge 4400 systems also include a system intrusion switch that signals appropriate server management software if the top cover is opened.
Getting Help
If at any time you do not understand a procedure described in this guide, or if your system does not perform as expected, Dell provides a number
of tools to help you. For more information on these help tools, see "Getting Help" in your Installation and Troubleshooting Guide.
