Front-Panel Indicators and Features
Back-Panel Features and Indicators
SCSI Hard-Drive Indicator Codes
Baseboard Management Controller 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.
The system front panel incorporates blue and amber system status indicators. The blue indicator lights up when the system is operating correctly. The amber indicator lights up when the system needs attention due to a problem with power supplies, fans, system temperature, or hard drives.
Table 2-1 lists the system's indicator patterns. Different patterns are displayed as events occur in the system.
Table 2-1. System Status Indicator Patterns
Figure 2-1 shows the controls, indicators, and connectors located behind the optional bezel on the system's front panel. Table 2-2 describes the front-panel features and indicators.
Figure 2-1. Front-Panel Features and Indicators
Table 2-2. Front-Panel LED Indicators, Buttons, and Connectors
Figure 2-2 shows the controls, indicators, and connectors 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 2-2. |
Figure 2-2. Back-Panel Features and Indicators
|
|
NOTE: To disconnect a network cable from the NIC, press the release latch located above the connector. See Figure 2-3. To facilitate installation of network cables with hooded connectors, use the RJ-45 extension cable provided with your system. |

If RAID is activated, two indicators on each of the hard-drive carriers provide information on the status of the SCSI hard drives. RAID can be enabled either by using ROMB on the optional riser card (when available) or by using a RAID expansion card connected to the backplane. See Figure 2-4 and Table 2-3. The SCSI backplane firmware controls the drive power-on/fault indicator.
Figure 2-4. SCSI Hard-Drive Indicators
Table 2-3 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 a RAID controller is not installed, only the "drive online" indicator pattern appears. The drive-activity indicator also blinks when the drive is being accessed. |
Table 2-3. Hard-Drive Indicator Patterns
|
Condition |
Indicator Pattern |
|---|---|
Identify drive | The green power-on/fault indicator blinks four times per second. |
Drive being prepared for removal | The green power-on/fault indicator blinks two times per second. |
Drive ready for insertion or removal | Both drive indicators are off. |
Drive being prepared for operation | The green power-on/fault indicator is on. |
Drive predicted failure | The power-on/fault indicator slowly blinks green, amber, and off. |
Drive failed | 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. |
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 2-1). Table 2-4 lists the power button indicator codes.
Table 2-4. Power Button Indicators
|
Indicator |
Function |
|---|---|
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 information on standby states, see your operating system documentation. |
The indicators on the optional redundant power supplies show whether power is present or whether a power fault has occurred (see Figure 2-5 and Table 2-5).
Figure 2-5. Redundant Power Supply Indicators
Table 2-5. Redundant Power Supply Indicators
|
Indicator |
Function |
|---|---|
Power supply status | Green indicates that the power supply is operational. |

Figure 2-6 and Table 2-6 describe the indicators on the NIC.
|
Link indicator |
Activity indicator |
Description |
|---|---|---|
Off | Off | The NIC is not connected to the network or the NIC is disabled in the System Setup screen. See "Using the System Setup Program" in the User's Guide. |
Green | Off | Indicates that the network adapter is connected to a valid link partner on the network, but data is not currently being sent or received. |
Green | Blinking amber | Indicates that network data is being sent or received. |
System messages appear on the screen during system boot to notify you of a possible problem with the system. Table 2-7 lists the system messages that can occur and the probable cause and corrective action for each message.
|
|
NOTE: If you receive a system message that is not listed in Table 2-7, 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. |

A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For example, before you format a diskette, a message will warn you that you may lose all data on the diskette. Warning messages usually interrupt the task and require you to respond by typing y (yes) or n (no).
|
|
NOTE: Warning messages are generated by either the application or the operating system. For more information, see "Finding Software Solutions" and the documentation that accompanied the operating system or application. |
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 in "Getting Help," and then follow the instructions in that section for obtaining technical assistance.
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.
The Baseboard Management Controller (BMC) enables you to configure, monitor, and recover systems remotely. BMC uses the system's serial port and integrated NIC1 to support fault logging and SNMP alerting.
|
|
NOTE: If the integrated network controller is used in an Ether Channel team or link aggregation team, the BMC management traffic will not function properly. For more information about network teaming, see the documentation for the network controller. |
For additional information on using BMC, see the documentation for the BMC and systems management applications.
