Table 2-2. Front-Panel Indicators, Buttons, and Connectors Indicator, Button, or Connector Description Blue and amber system status indicator The blue system status indicator lights during normal system operation. The amber system status indicator flashes when the system needs attention due to a problem with power supplies, fans, system temperature, or hard drives.
SCSI Hard-Drive Indicator Codes If an optional SCSI RAID controller is installed in the system, two indicators on each of the hard-drive carriers provide information on the status of the SCSI hard drives. See Figure 2-3 and Table 2-3. The SCSI backplane firmware controls the drive power-on/fault indicator. Figure 2-3. SCSI Hard-Drive Indicators Table 2-3 lists the drive indicator patterns. Different patterns are displayed as drive events occur in the system.
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. Power Indicator Codes 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).

Back to Contents Page I/O Connectors Dell™ PowerEdge™ 850 Systems Installation and Troubleshooting Guide I/O Connectors Serial Connector PS/2-Compatible Keyboard and Mouse Connectors Video Connector USB Connector Integrated NIC Connector Embedded Remote Access Ethernet Connector Network Cable Requirements I/O Connectors I/O connectors are the gateways that the system uses to communicate with external devices, such as a keyboard, mouse, printer, or monitor.
The default designation of the integrated serial connector is COM1. When you add an expansion card containing a serial connector that has the same designation as the integrated connector, the system's autoconfiguration feature remaps (reassigns) the integrated serial connector to the next available designation. Both the new and the remapped COM connectors share the same IRQ setting. COM1 and COM3 share IRQ4, while COM2 and COM4 share IRQ3.
NOTE: Installing a video card automatically disables the system's integrated video controller. Figure B-5. Video Connector Pin Numbers Table B-4.

Back to Contents Page Introduction Dell™ PowerEdge™ 850 Systems Installation and Troubleshooting Guide Other Information You May Need Your system includes the following significant service and upgrade features: l l Baseboard Management Controller (BMC), which monitors temperatures and voltages throughout the system and notifies you if the system overheats, if a system cooling fan malfunctions, or if a power supply fails.
Back to Contents Page Indicators, Messages, and Codes Dell™ PowerEdge™ 850 Systems Installation and Troubleshooting Guide Front-Panel Features Back-Panel Features NIC Indicators System Messages Diagnostics Indicator Codes System Beep Codes Warning Messages Diagnostics Messages Alert Messages Baseboard Management Controller Messages The system, applications, and operating systems can identify problems and alert you to them.
System identification button You can use the system identification buttons on the front and back panels to locate a particular system within a rack. When one of these buttons is pushed, the blue system status indicators on the front and back panels blink until one of the buttons is pushed again. You can also use the systems management software to cause the indicators to flash to identify a particular system.
Table 2-2. NIC Indicators Indicator Type Indicator Code Description Activity Off When off at the same time that the link indicator is off, the NIC is not connected to the network or the NIC is disabled by the System Setup program. See "Using the System Setup Program" in the User's Guide. Blinking Indicates that network data is being sent or received.
Error 8602: Auxiliary device failure. Verify that mouse and keyboard are securely attached to correct connectors. Loose or improperly connected mouse or keyboard cable; faulty mouse or keyboard. Gate A20 failure Faulty keyboard controller (faulty system board). See "Getting Help." General failure The operating system is unable to carry out the command. This message is usually followed by specific information. Take the appropriate action to resolve the problem.
problem persists, see "Getting Help." Plug & Play Configuration Error Error encountered in initializing PCI device; faulty system board. Install the NVRAM_CLR jumper and reboot the system. See Figure A-2 for jumper location. Check for a BIOS update. If the problem persists, see "Troubleshooting Expansion Cards" in "Troubleshooting Your System." If the problem persists, see "Getting Help." Primary drive 0/1 configuration error Faulty drive. Parameters failure.
Table 2-4. Diagnostic Indicator Codes Code Causes Corrective Action Possible processor failure. See "Troubleshooting the Microprocessor" in "Troubleshooting Your System." Memory failure. See "Troubleshooting System Memory" in "Troubleshooting Your System." Possible expansion card failure. See "Troubleshooting Expansion Cards" in "Troubleshooting Your System." Possible video card failure. See "Troubleshooting Expansion Cards" in "Troubleshooting Your System." Diskette drive or hard drive failure.
System Beep Codes If an error that cannot be reported on the screen occurs during POST, the system may emit a series of beeps that identifies the problem. NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue beep codes related to those peripherals. If a beep code is emitted, write down the series of beeps and then look it up in Table 2-5.
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 the documentation that accompanied the operating system or application.
