Obtaining Technical Assistance
This section describes the major hardware and software features of your system, including front- and back-panel indicators, and provides information about connecting external devices to the system and using power protection devices. It also lists other documents that you may need to install and operate your system, as well as how to obtain technical assistance.
Front-Panel Features
Figure 1-1 shows the front-panel features and indicators of the system. To remove the optional bezel and access the switches and indicators on the front panel, press the latch at each end of the bezel. See Figure 1-1.
Figure 1-1. Front-Panel Features
The power button controls the power input to the system's power supply.
The two system identification buttons on the front and back panels can be used to locate a particular system within a rack. When one of these buttons is pushed or the systems management software is used to identify the system, the blue system status indicators on the front and back of the system blink. (To stop the indicator from blinking, press one of the identification buttons a second time, or use the systems management software.)
The front panel also incorporates a USB connector and a video connector. See Figure 1-1.
Table 1-1 describes the indicators on the system front panel.

Description
|
Blue/amber system status indicator | The blue system status indicator lights up during normal system operation. You can also use the systems management software to cause this indicator to flash to identify a particular system. The amber system status indicator flashes when the system needs attention due to a system problem. |
Hard-drive indicator | The green hard-drive activity indicator flashes when the hard drives are in use. |
NIC1 and NIC2 link indicators | The indicators for the two integrated network adapters light if the network adapters are connected to the network. |
Power indicator | The green indicator in the center of the power button flashes if AC power is available to the system, but the system is not powered on. The green indicator is on when the system is powered on. If the system is not connected to AC power, the green indicator is off. |
Connecting External Devices
When connecting external devices to your system, follow these guidelines:
- Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are normally included with your operating system software or with the device itself.) Check the documentation that accompanied the device for specific installation and configuration instructions.
- Always attach external devices while your system is turned off. Next, turn on any external devices before turning on the system (unless the documentation for the device specifies otherwise). If the system does not appear to recognize the device, try turning on the system before turning on the device.
For information about individual connectors, see "I/O Connectors" in your Installation and Troubleshooting Guide. For information about enabling, disabling, and configuring I/O ports and connectors, see "Using the System Setup Program."
Back-Panel Features
Figure 1-2 shows the back-panel features of the system.

For more information about specific features, see "Technical Specifications."
Supported Operating Systems
Your system supports the following operating systems:
- Microsoft® Windows® 2000 Server
- Microsoft Windows Server 2003, Enterprise Edition and Web Edition
- Red Hat® Enterprise Linux ES (version 3) and AS (version 3) (when available)
- Novell® NetWare® 5.1 and 6.5
Power Protection Devices
Certain devices protect your system from the effects of problems such as power surges and power failures.
- PDU Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.
- Surge protector Prevents voltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not provide protection from brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
- 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.
- 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 timefrom 15 minutes to approximately an hour. A UPS that provides only 5 minutes of battery power allows you to shut down the system. Use surge protectors and PDUs with all universal power supplies, and ensure that the UPS is UL-safety approved.
Other Documents You May Need
