System Identification Indicators
Obtaining Technical Assistance
Your system is a multipurpose, highly-available, rack-dense server with two Intel® Xeon microprocessors.
This section describes the major hardware and software features of your system and provides information about the system status indicators, and indicators on the system's front and back panels. It also provides information about other documents you may need when setting up your system and how to obtain technical assistance.
The system's bezel has an indictor that can represent system status when the bezel is installed (see Figure 1-1). The indicator signifies when the system is operating properly, when the system needs attention, or when the system is being identified (see "System Identification Indicators"). The back-panel indicator connector allows an indicator to be attached that will function the same as the bezel system status indicator. A caution code signifies a problem with microprocessors, power supply, system or power-supply fans, system temperature, hard drives, system memory, expansion cards, or the integrated SCSI controller. (See your Installation and Troubleshooting Guide for more information.) When the bezel is off, the LCD status display assumes all of the functions of the system status indicator (see "Status LCD").
Table 1-1 and Table 1-2 list the system's status indicator codes.

Indicator |
Indicator Code |
---|---|
Off | No power is available to the system, or the system is not powered on. |
Blue | The system is operating normally. |
Amber blinking | The system has detected an error and requires attention. |
Blue blinking | The system is identifying itself. NOTE: Server management software causes the indicator to blink to identify a particular system. |
You can use identification buttons on the front and back panels to locate a particular system within a rack. When you press either of these buttons, the identification indicator on the back and status indicator on the front bezel blink until you press one of the buttons again. If the bezel is removed, the LCD display blinks blue.
See Figure 1-2 to locate the front-panel system identification button. See "Back-Panel Features" to locate the back-panel system identification button and indicator.
Additional indicators for system power and drives are located behind the bezel. The front-panel status LCD provides information by using an alphanumeric character display (see "Status LCD").
Figure 1-2 shows the front-panel features of the system. Table 1-3 describes the front-panel features.

Description |
---|---|
Power button | Turns system power off and on.
The button is enabled in the System Setup program. When disabled, the button can only turn system power on. |
Power indicators | Provides information on power status (see "NIC Indicators"). |
CD and diskette drive indicators | Indicate read or write access to the respective drive. |
hard drive indicators | Provide information on the status of the respective hard drive (see "SCSI Hard-Drive Indicators"). |
NIC indicators | Indicate whether the NIC has a valid link to the network (see "NIC Indicator Codes"). |
Status LCD | Signifies when the system is operating correctly or when the system needs attention (see "Status LCD"). |
System identification button | Used to identify a particular system (see "System Identification Indicators"). |
NMI button | Can be used to troubleshoot software and device driver errors when using certain operating systems. This button is often referred to as a "force dump switch" and can be pressed using the end of a paper clip. When the option is enabled in the System Setup program and the button is pressed, an NMI alerts the system. Use this button only if directed to do so by qualified support personnel or by the operating system's documentation. |
The front panel also features a USB connector, video connector, and PS/2 connector (see Figure 1-2) for connecting a mouse and keyboard using a Y-cable.
The system has indicators on the front panel and the power supplies that denote system power status (see Figure 1-2).
The power button controls the AC power input to the system's power supplies. The power button indicator can provide information on power status.
Table 1-4 lists the power-button indicator codes.
Indicator |
Indicator Code |
---|---|
On | Indicates that power is supplied to the system, and the system is operational. |
Off | Indicates that no power is supplied to the system. |
Blinking | Indicates that power is supplied to the system, but the system is in a standby state. For more information on standby states, see your operating system documentation. |
Each SCSI hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 1-3). The indicators provide information on the status of the respective hard drive. Table 1-5 lists the drive indicator codes.
Figure 1-3. SCSI Hard-Drive Indicators
Table 1-5 lists the drive indicator codes. Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive fail" code appears. After the drive is selected for removal, the "prepared for removal" code appears. After the replacement drive is installed, the "prepared for operation, drive online" code appears.
Indicator |
Indicator Code |
---|---|
Drive bay empty, ready for insertion or removal | Off |
Drive being prepared for operation, drive online | Steady green |
Identify drive | Blinks green four times per second |
Drive being prepared for removal | Blinks green twice per second at equal intervals |
Drive rebuilding | Blinks green twice per second at unequal intervals |
Drive failed | Blinks amber four times per second |
Predicted failure for the drive | Blinks green, then amber, and then off, repeating this sequence every two seconds |
Drive online | Steady green |
NOTE: The "drive busy" indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive. |
The system's bezel indicator (see Figure 1-2) shows when the system is operating correctly, when the system needs attention, or when the system is being identified (see "System Identification Indicators"). When the bezel indicator signals an error condition, open the bezel to see further information provided be the LCD.
The LCD can display two lines of alphanumeric characters. The display codes are presented in two color combinations:
For more information about LCD status messages, see your Installation and Troubleshooting Guide.

Each NIC on the back panel has an indicator that provides information on network activity and link status (see Figure 1-6). Table 1-8 lists the NIC indicator codes on the back panel.
The front panel has a link indicator for each NIC (see Figure 1-2). Each indicator signifies whether the corresponding NIC is connected to a valid link partner on the network.

The following software is included with your system:
A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.
Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's AC power source voltage at a fairly constant level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectorsup to several hundred dollars. However, these devices cannot protect against a complete loss of power.
UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when AC power is unavailable or unusable. The battery is charged by the AC power while it is available so that once AC power is lost, the battery can provide power to the system for a limited amount of timefrom 15 minutes to an hour or sodepending on the UPS system.
UPS systems that provide only 5 minutes of battery power allow you to conduct shutdown of the system but are not intended to provide continued operation. Use surge protectors with all UPS systems, and ensure that the UPS systems are UL safety approved.
