Server Module Indicators and Features
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 the 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 2-1 shows the system with six server modules and their locations.
Each server module has five indicators and one power button on the front of the server module (see Figure 2-2). The indicators include a status indicator, two network switch module link indicators, a hard-drive indicator, and a power indicator. The server module has a USB port on the front of the module. The USB port is used to connect either the USB diskette drive or USB CD drive. Table 2-1 provides details about the operation of the indicators.
 |
NOTE: The USB port can only be used with the USB diskette drive or USB CD drive supplied by Dell. The USB port will not operate properly with any other USB device. |

|
Indicator Type |
Indicator |
Indicator Code |
|---|---|---|
Status | Off | Power is not available to the server module, the server module is not turned on, or the server module is initializing. |
Blue | The module is operating normally. | |
Blue blinking | The module is identifying itself. NOTE: Systems management software causes the indicator to blink to identify a particular module. | |
Amber | The system management module is not installed. See "Installing a System Management Module" in "Installing System Options." | |
Amber blinking | Indicates a fault with the system or server module. See "Troubleshooting Your System." NOTE: If the status indicator is blinking amber on all installed server modules, a system fault has occurred. See "Troubleshooting System Components" in "Troubleshooting Your System." | |
Link indicators (2) | Off | Indicates that the server module does not have a link to the network switch module. |
Green on | Indicates that the server module has a valid link to the network switch module. NOTE: If only one network switch module is installed, only one link indicator will operate. | |
Green blinking | Indicates network switch module activity. | |
Hard-drive indicator | Green blinking | Indicates hard drive activity. |
Power indicator | Green blinking | Indicates that the module is installed correctly and can be turned on by pressing the power button. |
Green (steady) | Indicates that power is supplied to the server module, and the module is operational. | |
Amber blinking | Indicates a power fault or other condition that causes the server module to shut down. See "Troubleshooting Power Supplies" and "Troubleshooting Server Module Components" in "Troubleshooting Your System." | |
Power button | None | Turns the server module power off and on.
The button is enabled in the System Setup program. When disabled, you can only use the button to turn on the server module. |
|
NOTE: If the hard-drive indicator and the link indicators blink one after another, the server module is initializing. The initialization time varies based on the number of server modules installed and Internet activity. |
The back of the system provides access to the network switch modules (2), the system management module, the fans, and power supplies (see Figure 2-3). Table 2-2 lists the back-panel features.

Activity Indicator |
Indicator Code |
|---|---|---|
DC power indicator | Green | Indicates that the power supply is operational. |
AC power indicator | Green | Indicates that AC power is present at the power supply and that the system is connected to an AC power source. |
Fault indicator | Amber | Indicates that the power supply is in a fault condition. See "Troubleshooting Power Supplies" in "Troubleshooting Your System." |
Each system can accommodate up to two network switch modules. The network switch modules provide information about network activity and link status and a system fault indicator (see Figure 2-5). The switch also provides an external RJ11 connection to a serial null modem cable (provided by Dell) used for switch setup and configuration. The RJ11 is not used during normal system operation. Table 2-4 provides details about the operation of the indicators.
|
NOTE: Do not connect the configuration port to the network. |

The system management module provides:
|
NOTE: Connect the analog rack interface port only to an external KVM over IP switch provided by Dell. |
In addition, a system status connector allows you to attach the system status cable so that you can monitor system status after the system is mounted in a rack (see Figure 2-6). Table 2-5 provides information about the status indicators.

Server module messages alert you to a possible operating system problems or to a conflict between the software and hardware. Table 2-7 lists the server module error messages that can occur and the probable cause for each message.
|
NOTE: If you receive a server module message that is not listed in Table 2-7, 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 server module 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 in "Getting Help," and then look it up in Table 2-8. If you are unable to resolve the problem by looking up the meaning of the beep code, use system diagnostics to identify the cause. If you are still unable to resolve the problem, see "Getting Help."

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.
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.
