Front-Panel Indicators and Features
Dell™ PowerEdge™ 2600 Systems Service Manual

|
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 indicators, codes, and messages can alert you when the system is not functioning properly:
The system indicators and features are illustrated in Figure 3-1 through Figure 3-6. 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 has indictors that can represent system status. When the bezel is installed, the bezel system-status indicator (see Figure 3-1) 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 the integrated SCSI controller. When the bezel is off, the system status indicators on the system (see Figure 3-2) assumes the same functions as the bezel system status indicator.
Table 3-1 lists the system's status indicator codes.
Figure 3-1. System-Status Indicators

Bezel Indicators |
Indicator Code | |
|---|---|---|
|
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 green activity indicator.s
Figure 3-2 shows the front-panel indicators and features of the system. Table 3-2 describes the front-panel features.

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. | ||
Hard-drive indicators | Provide information on the status of the respective hard drive (see "Hard-Drive Indicator Codes"). | ||
NIC indicators | Indicate whether the NIC has a valid link to the network (see "NIC Indicator Codes"). | ||
NMI button | Troubleshoots software and device driver errors when using certain operating systems. You can press this button using the end of a paper clip. The NMI option is enabled in the System Setup program.

Component |
Description |
|---|---|
NIC indicators | Provides information on NIC status (see "NIC Indicator Codes"). |
ERA/O Ethernet connector indicators | Provides information about the ERA/O Ethernet connector status (see "ERA/O Ethernet Connector Indicator Codes"). |
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 3-2).
Table 3-4 lists the power-button indicator codes.
Each hot-pluggable power supply has indicators that can provide information on power status, fault, and the presence of power (see Figure 3-4). Table 3-5 lists the power-supply indicator codes.
Figure 3-4. Power-Supply Indicators
Each hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 3-5). The indicators provide information on the status of the respective hard drive. Table 3-6 lists the drive indicator codes.
Figure 3-5. Hard-Drive Indicators
Table 3-6 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.
Each NIC on the back panel has an indicator that provides information on network activity and link status (see Figure 3-6). Table 3-7 lists the NIC indicator codes on the back panel.
The front panel has a link indicator for each NIC (see Figure 3-2). Each indicator signifies whether the corresponding NIC is connected to a valid link partner on the network.
The optional embedded remote access (ERA/O) Ethernet connector indicators on the back panel provide information on network activity and link status for the ERA/O Ethernet connector (see Figure 3-7). Table 3-8 lists the ERA/O Ethernet connector indicator codes.
Figure 3-7. ERA/O Ethernet Connector
Each individual fan has a status indicator adjacent to the fan connectors on either the system board or on the SCSI backplane board (see Figure 3-8). To locate the fan connectors on the system board, see Figure 5-2. To locate the fan connector on the SCSI backplane board, see Figure 5-4. Table 3-9 lists the cooling fan indicator codes.
Figure 3-8. Cooling Fan Status Indicators

Indicator Code |
|---|---|
Off | The fan is not installed. |
Green | The fan is operating normally. |
Amber blinking | The fan is malfunctioning. |
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, make a note of it and then look it up in Table 3-10. 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.
 |
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to those peripherals. |
|
NOTE: Before you perform any procedures described in Table 3-10, see "External Visual Inspection." |

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 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. The message usually provides information for identification of the faulty component.
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 system board as a series of five lit or flashing LEDs. The LEDs can only be seen when the system cover is removed (see Figure 3-9). Table 3-12 defines these LED codes.
