  Alert Messages


The system, applications, and operating systems can identify problems and alert you to them. Any of the following can indicate when the system is not operating properly:

This section describes each type of message, lists the possible causes, and provides steps to resolve any problems indicated by a message. The system indicators and features are illustrated in this section.


Indicators on the Optional Bezel

The optional system bezel incorporates a system status indicator divided into blue and amber system status indicators. See Figure 3-1. The blue indicator lights up when the system is operating correctly. The amber caution indicator lights up when the system needs attention due to a problem with power supplies, fans, system temperature, system memory, or hard drives.

Table 3-1 lists the system's indicator patterns. Different patterns are displayed as events occur in the system.

Figure 3-1. System Status Indicators

Table 3-1. System Status Indicator Patterns  

Blue Indicator

Amber Caution Indicator

Description

Off

Off

Power is not available to the system, or power is available to the system, but the system is not powered on.

Off

Blinking

The system has detected an error.

On

Off

Power is on, and the system is operational.

Blinking

Off

The indicator has been activated to identify the system in a rack.

NOTE: While the system is being identified, the blue indicator blinks even though an error has been detected. After the system is identified, the blue indicator stops blinking and the amber indicator resumes blinking.


Front-Panel Features

Figure 3-2 shows the controls, indicators, and connectors located behind the optional bezel on the system's front panel. Table 3-2 provides a description of each feature.

Figure 3-2. Front-Panel Features

Table 3-2. Front-Panel LED Indicators, Buttons,
and Connectors

or Connector

Icon

Description

Blue system status
indicator

The blue system status indicator lights up during normal system operation. Both the systems management software and the identification buttons located on the front and back of the system can cause the blue system status indicator to flash to identify a particular system.

Amber system status indicator

The amber system status indicator flashes when the system needs attention. Check for a problem with the power supplies, fans, system temperature, or hard drives.

NOTE: If the system is connected to AC power and an error has been detected, the amber system status indicator flashes regardless of whether the system has been powered on.

NIC1 and NIC2 link and activity indicators


The link and activity indicators for the two integrated NICs light intermittently when the NICs are in use.

NOTE: If you purchased a 400-MHz front-side bus system with a preinstalled Gigabit PCI network card, the front-panel link and activity indicators are disabled.

 

 

Hard-drive activity indicator

The green hard-drive activity indicator flashes when the hard drives are in use. See Figure 3-3 for more information on hard-drive indicators.

Power-on indicator, power button

The power-on indicator lights when the system power is on.

The power button controls the DC power supply output to the system.

NOTE: If you turn off the system using the power button and the system is running an ACPI-compliant operating system, the system performs a graceful shutdown before the power is turned off. If the system is not running an ACPI-compliant operating system, the power is turned off immediately after the power button is pressed.

Identification button

The 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, the blue system status indicator on the front and back blinks until one of the buttons is pushed again.

USB connector

Connects a USB 1.1-compliant device to the system.

Video connector

Connects a monitor to the system.

SCSI Hard-Drive Indicator Codes

If the optional ROMB card is activated, two indicators on each of the hard-drive carriers provide information about the status of the hard drives. See Figure 3-3 and Table 3-3. The SCSI backplane firmware controls the drive power-on/fault indicator.

Figure 3-3. SCSI Hard-Drive Indicators

Table 3-3 lists the drive indicator patterns. Different patterns are displayed as drive events occur in the system. For example, if a hard drive fails, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

NOTE: If the optional ROMB card is not installed, only the "drive online" indicator pattern appears. The drive-activity indicator also blinks when the drive is being accessed.

Table 3-3. SCSI Hard-Drive Indicator Patterns  

Condition

Indicator Pattern

The amber power-on/fault indicator blinks four times per second.

Drive rebuilding

The green power-on/fault indicator blinks slowly.

Drive online

The green power-on/fault indicator is on.


Back-Panel Features

Figure 3-4 shows the controls, indicators, connectors, and expansion slots located on the system's back panel.

NOTE: Connect the power cable to connector PS1 if your system only has one power supply. See Figure 3-4.

Figure 3-4. Back-Panel Features and Indicators


Power-Supply Features

Each hot-pluggable power supply has three indicators, visible when the system covers are open, that indicate whether power is present or whether a power fault has occurred. See Figure 3-5 and Table 3-4 for more information about the indicators. See "System Covers" for information about accessing the inside of the system.

System Messages

System messages alert you to a possible operating system problem or to a conflict between the software and hardware. Table 3-5 lists the system error messages that can occur and the probable cause for each message.

NOTE: If you receive a system message that is not listed in Table 3-5, check the documentation for the application that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action.

When a beep code is emitted, record it on a copy of the Diagnostics Checklist (located in "Getting Help" in the Installation and Troubleshooting Guide), and then look it up in Table 3-6. If you are unable to resolve the problem by looking up the meaning of the beep code, use the system diagnostics to identify a more serious cause.

Warning Messages

A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you format a diskette, a message may warn you that you may lose all data on the diskette, as a way to protect against inadvertently erasing or writing over the data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no).

NOTE: Warning messages are generated by either the application program or the operating system. See "Finding Software Solutions" in the Installation and Troubleshooting Guide and the documentation that accompanied the operating system or application program for further information.

Diagnostics Messages

When you run system diagnostics, an error message may result. Diagnostic error messages are not covered in this section. Record the message on a copy of the Diagnostics Checklist (located in "Getting Help" in the Installation and Troubleshooting Guide), and then follow the instructions in that section for obtaining technical assistance.


Alert Messages

Systems management software generates alert messages for your system. Alert messages include information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For more information, see the systems management software documentation.
