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.
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.
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).
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.
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 connector on 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.

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.
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).
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.
