Front-Panel Indicators and Features
Back-Panel Indicators and Features
ERA Ethernet Connector Indicators Codes (Optional)
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 and codes can indicate when the system is not functioning properly:
The system indicators and features are illustrated in Figure 2-1 through Figure 2-6. 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. To determine what type of message you have received, read the following subsections.
The system's bezel has an indictor that can represent system status when the bezel is installed (see Figure 2-1). The indicator signifies when the system is operating properly or when the system needs attention.
A caution code signifies a problem with microprocessors, power supply, system or power-supply fans, system temperature, hard drives, system memory, expansion cards, or integrated SCSI controller.
Table 2-1 lists the system's status indicator codes.
Figure 2-1. System-Status Indicators

|
Status |
Caution | |
Off | Off | No power is available to the system, or the system is not powered on. |
On | Off | The system is operating normally. |
Off | Blinking | The system has detected an error and requires attention. |
Blinking | Off | The system is identifying itself (see "Front-Panel Indicators and Features"). |
Blinking | Blinking or Off | Systems management software causes the status indicator to blink to identify a particular system. |
Additional indicators are located behind the bezel on the power supplies, hard drives, and the control panel. The CD and diskette drives have a green activity indicator.
Figure 2-2 shows the front-panel indicators and features of the system. Table 2-2 describes the front-panel features.

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. For more information, see the User's Guide and the operating system's documentation. |
Power indicator | Provides information on power status (see "Power Indicator Codes"). |
Power-supply indicators | Provide information on power status (see "Power-Supply Indicator Codes"). |
CD and diskette drive indicators | Indicates read or write access to the respective drive. |

Description |
|---|---|
NIC indicators | Provides information on NIC status (see "NIC Indicator Codes"). |
ERA Ethernet connector indicators | Provides information about the ERA Ethernet connector status (see "ERA Ethernet Connector Indicators Codes (Optional)"). |
The system has indicators on the power button and on the power supplies that signify system power status.
The power button controls the power input to the system's power supplies. The power-button indicator can provide information on power status (see Figure 2-2).
Table 2-4 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 hot-pluggable power supply has indicators that can provide information on power status, fault, and the presence of power (see Figure 2-4). Table 2-5 lists the power-supply indicator codes.
Figure 2-4. Power-Supply Indicators
|
Indicator |
Indicator Code |
|---|---|
Power-on | Green indicates that the power supply is operational. |
Fault | Red indicates a problem with the power supply (fan failure, voltage error, etc.). |
Power present | Green indicates that power is present at the power supply and that the system is connected to a power source. |
Each hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 2-5). The indicators provide information on the status of the respective hard drive. Table 2-6 lists the drive indicator codes.
Figure 2-5. Hard-Drive Indicators
Table 2-6 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 "preparing for removal" code appears. After the replacement drive is installed, the "preparing for operation, drive online" code appears.
|
Drive Status Indicator |

NOTE: The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive. | |
Each NIC on the back panel has an indicator that provides information on network activity and link status (see Figure 2-6). Table 2-7 lists the NIC indicator codes on the back panel.
The front panel has a link indicator for each NIC (see Figure 2-2). Each indicator signifies whether the corresponding NIC is connected to a valid link partner on the network.

System messages appear on the console during POST to notify you of a possible problem with the system. If you are performing console redirection, system messages will appear on the remote console. Table 2-10 lists the system messages that can occur and the probable cause for each message.
 |
NOTE: If you receive a system message that is not listed in Table 2-10, check the documentation for the application program that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action. |
|
NOTE: Before you perform any procedures described in Table 2-10, see "Before You Begin" in "Troubleshooting Your System." |

When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identifies the problem.
When a beep code is emitted, record it on a copy of the Diagnostics Checklist in "Getting Help," and then look it up in Table 2-11. 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. If you are still unable to resolve the problem, see "Getting Help."
|
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to those peripherals. |
|

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 "Finding Software Solutions" and the documentation that accompanied the operating system or application program. |
When you run a test group or subtest in 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 (see "Getting Help"), and then follow the instructions in that section for obtaining technical assistance.
The optional systems management software generates alert messages for your 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.
|
CAUTION: The power supplies in this system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. |
Errors that cannot be reported on the monitor during the boot routine can appear on the the system board as a series of five lit or flashing LEDs. The LEDs can only be seen when the system cover is removed. To obtain more information about the system board LED codes, see "Getting Help" for instructions about obtaining technical assistance.
