Obtaining Technical Assistance
This section describes the major hardware and software features of your system and provides information about the indicators on the system's front and back
panels. It also provides information about other documents you may need to set up your system and how to obtain technical assistance.
Front-Panel Features and Indicators
Figure1-1 shows the front-panel features and indicators of the system. Table1-1 describes some of these features and indicators. For more information about
indicator codes, see your Installation and Troubleshooting Guide.
Figure 1-1. Front-Panel Features and Indicators
Table 1-1. Front-Panel Buttons and Indicators
Back-Panel Features
Figure1-2 and Table1-2 provide information about the back-panel features and diagnostic indicators of the system. Figure1-3 and Table1-3 provide
information about NIC indicators. For more information about back-panel indicators, see your Installation and Troubleshooting Guide.
Figure 1-2. Back-Panel Features
Button/Indicator
Description
Power button
Turns system power off and on.
If you turn off the system using the power button, the system can perform an orderly shutdown before power is turned off. If the
power button is pressed for more than 4 seconds, the system power will turn off regardless of the current operating system state.
Power indicator
Off indicates the system is off. Solid green indicates that the system is in a normal operating state. Amber blinking indicates that the
system is powering up. Solid amber indicates that the power supply is good.
To exit from a power-saving state, briefly press the power button or click or move the mouse.
For more information, see your Installation and Troubleshooting Guide.
Hard-drive activity
indicator
Green blinking indicates data is being read from or written to the internal hard drives that are connected to the hard-drive controller.
Diskette drive
indicator
Green light indicates disk-drive activity.

Indicator
Normal Operation
Error Condition
Link
Green indicates that a 10-Mbps network connection exists.
Orange indicates that a 100-Mbps network connection exists.
Yellow indicates that a 1-Gbps(or1000Mbps)networkconnection
exists.
Off indicates that the NIC is not detecting a physical connection to the
network.
Activity
Flashing or steady yellow indicates that the NIC is transmitting or
receiving network data.
When off at the same time that the link indicator is off, the NIC is not
connected to the network.
NOTE: If the NIC is disabled in System Setup, both the link and activity indicators will be "off" regardless of whether an active network connection is present.
NOTE: Use the System Setup program to view processor information. See "Using the System Setup Program."

Supported Operating Systems
Your system supports the following operating systems:
l Microsoft®Windows®Server 2003, Standard Edition
l Windows Small Business Server 2003
l Red Hat®Enterprise Linux ES (Version 3)
Power Protection Devices
Certain devices protect your system from the effects of problems such as power surges and power failures.
l PDU — Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.
l Surge protector — Prevents voltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical
outlet. They do not protect against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
l Line conditioner — Maintains a system's AC power source voltage at a moderately constant level and provides protection from brownouts, but does not
protect against a complete power loss.
l UPS — Uses battery power to keep the system running when AC power is unavailable. The battery is charged by AC power while it is available so that
after AC power is lost, the battery can provide power to the system for a limited amount of time—from5minutestoapproximatelyanhour.AUPSthat
provides only 5 minutes of battery power allows you to save your files and to shut down the system. Use surge protectors and PDUs with all universal
power supplies, and ensure that the UPS is UL-safety approved.
