In addition to information provided in this manual and the User’s Guide that came with the system, Dell provides the Diagnostics and Troubleshooting Guide for troubleshooting procedures and instructions on using the Dell diagnostics to test the computer system.
&+$37(5 6\VWHP 2YHUYLHZ Dell® PowerEdge® 6350 systems are feature-rich, enterprise-class server systems that use Intel® Pentium® II Xeon™ microprocessor(s) with MMX™ technology and incorporate a high-performance PCI local bus. The PowerEdge 6350 systems have been rack-optimized and designed for better serviceability and increased reliability. The two panel doors on top of the chassis allow easy access to the system board for performing processor, memory, and expansion-card upgrades.
microprocessors in this system; the upgrade kit from Dell contains the correct version for this system. A minimum of 128 MB of system memory, upgradable to a maximum of 4 GB by installing combinations of 32-, 64- (when available), 128-, and 256-MB buffered EDO DIMMs in the 16 DIMM sockets on the memory board. BIOS in upgradable flash memory on the PCI bus. Up to three hot-pluggable 1-inch SCSI hard-disk drives.

&+$37(5 %DVLF 7URXEOHVKRRWLQJ This chapter describes basic troubleshooting procedures that can help you diagnose a computer system problem. These procedures can often reveal the source of a problem or indicate the correct starting point for troubleshooting the system. For a brief explanation of how to load and start the system diagnostics, see “Running the Dell Diagnostics” found later in this chapter.
3. Observe the user to determine if he or she is making an error, such as typing an incorrect key combination or entering a command incorrectly. Is the problem a result of user error? Yes. Instruct the user in the proper procedure, or direct him or her to the appropriate user documentation for the correct procedure. No. Proceed to the next section, “External Visual Inspection.
7. Inspect all external monitor controls for any obvious damage or improper settings. For proper settings of the video monitor controls, see the documentation for the monitor. 8. Inspect the keyboard to ensure that no keys are sticking. If one or more keys are sticking, it may be necessary to replace the keyboard. 9. Inspect the exterior of the computer, including all controls and indicators, and all user-accessible data storage devices for any signs of physical damage.
3. Watch the Num Lock, Caps Lock, and Scroll Lock indicators on the upperright corner of the keyboard. After all three indicators flash momentarily, and following a long pause (approximately 30 seconds), the Num Lock indicator should light up and remain on (unless the Num Lock option is set to Off in the System Setup program). Do these indicators flash on and off within approximately 10 seconds after the boot routine starts? Yes. Proceed to step 4. No. Troubleshoot the system power supplies.

5. Check all cable connectors inside the computer to verify that they are firmly attached to their appropriate connectors. 6. Close the right and left panel doors. 7. Reconnect the computer and any attached peripherals to their power sources, and turn them on. Does the problem appear to be resolved? Yes. No further steps are necessary. No. Proceed to the next section, “Eliminating Resource Conflicts,” and to “Getting Help” found later in this chapter.
