Alert Messages |
Applications, operating systems, and the system itself are capable of identifying problems and alerting you to them. When a problem occurs, a message may appear on the monitor or a beep code may sound.
A variety of messages can indicate when the system is not operating properly:
The system indicators and front- and back-panel features are illustrated in this section. This section also describes each type of message and lists the possible causes and actions you can take to resolve any problems indicated by a message.
Figure 3-1, Figure 3-2, and Figure 3-3 show the system's front-panel features. Table 3-1 describes the front-panel controls and indicators.

Component |
Description |
|---|---|
Power button | Turns system power off and on.
The power button is enabled in the System Setup program. When disabled, the button can only turn the system power on. For more information, see "Using the System Setup Program" and the operating system's documentation. |
Reset button | Restarts the system. |
Power indicator | Provides information on power status (see "Power Indicator Codes"). |
Hard-drive activity indicator | Indicates read or write access to a hard drive. |
Diskette and CD drive indicators | Indicate read or write access to the respective drive. |
Figure 3-4 shows the back-panel features of the system. Table 3-2 describes the back-panel features.
Figure 3-4. Back-Panel Features
|
Component |
Description |
|---|---|
Power connector | Connects the system's power supply to a power source. |
Power cable strain relief loop | Relieves strain on the power cable. |
NIC indicators | Provide information on NIC status (see "NIC Indicator Codes"). |
Expansion slots | Provide two 64-bit, 100-MHz slots, two 64-bit, 66-MHz slots, and two 32-bit, 33-MHz slots. |
I/O ports and connectors | Connect peripheral devices to the system. |
Kensington lock | Secures the system. |
The power button on the front panel controls the power input to the system's power supplies. The power indicator can provide information on power status (see Figure 3-3). Table 3-3 lists the power button indicator codes.
The indicators on the optional redundant power supplies show whether power is present and whether a power fault has occurred (see Figure 3-5).
Figure 3-5. Redundant Power Supply Indicators
Each hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 3-6). The indicators provide information on the status of the respective hard drive.
Figure 3-6. Hard-Drive Indicators
Table 3-5 lists the drive-status 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 "preparing for removal" code appears. After the replacement drive is installed, the "preparing for operation, drive online" code appears.
The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive.
The NIC connectoron the back panel has an indicator that provides information on network activity and link status (see Figure 3-7). Table 3-6 lists the NIC indicator codes.
Table 3-7 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 3-7, see the documentation for the application that is running when the message appears and/or the operating system documentation for an explanation of the message and recommended action. |

When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identify the problem.
|
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to these peripherals. |
When a beep code is emitted, record it on a copy of the Diagnostics Checklist and then look it up in Table 3-8. If you are unable to resolve the problem by looking up the meaning of the beep code, use the system diagnostics to identify the cause.

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. 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. For more information, see the Installation and Troubleshooting Guide and the documentation that accompanied the operating system or application program. |
When you run a test group or subtest in the 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.
Systems management software generates alert messages for the system. For example, the software generates messages that appear in the SNMP trap log file. Alert messages consist of information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For more information, see the systems management software documentation.
