General Troubleshooting Update System Software Important: Whenever possible before beginning troubleshooting, ensure the latest software and firmware updates have been applied. Troubleshooting Theory For general information on troubleshooting theory, refer to: http://service.info.apple.com/service_training/en/006/troubleshoot/index.php?page=intro Emerging Issues For the latest on troubleshooting issues, refer to: http://support.apple.
Xserve Firmware Updates Firmware is the name given to software that is written into memory circuits, such as flash memory, that will hold the software code indefinitely, even when power is removed from the hardware. Firmware on Intel Mac computers is designed to be updated if necessary through a software update. EFI and SMC firmware is stored on the Xserve (Early 2009) backplane board. EFI firmware updates update the Boot ROM, and SMC updates update the System Management Controller firmware.
DIMMs must fit these specifications: • PC3-8500,1066 MHz, DDR3 SDRAM UDIMMs • 72-bit wide, 240-pin modules • 36 memory ICs maximum per UDIMM • Error-correcting code (ECC) For proper operation of Xserve (Early 2009) computers, Apple recommends using only Appleapproved DIMMs. Refer to GSX for Apple DIMM service part numbers. Memory from older Xserve computers is not compatible with Xserve (Early 2009). Single Processor Single-processor (quad-core) computers have six memory slots.
Dual Processor Dual-processor (eight-core) computers have twelve memory slots. You can install 1 GB, 2 GB, or 4 GB DIMMs for a total of up to 48 GB of memory. You can install different size DIMMs. in Xserve (Early 2009) However, for best performance, Apple recommends you install equal-size DIMMs (all 1, 2, or 4 GB) filling the slots in the order listed in this table.
Memory Slot Utility If you install different size DIMMs in single-processor or dual-processor computers, follow the order in the tables above. If the DIMM configuration you install doesn’t provide optimized performance, the Memory Slot Utility will appear on screen and recommend an improved configuration. To use the Memory Slot Utility again, go to /System/Library/Core Services.

Diagnostic LEDs Logic Board Diagnostic LEDs The Xserve (Early 2009) logic board includes a set of LEDs to help service providers troubleshoot the computer. The LEDs are located on the logic board below the DIMM connectors, at the rear of the unit, to the left side of the unit (looking from the back), and on the Drive Interconnect Backplane or Xserve RAID Card. Some tips: • You must remove the unit from its rack and place it on a sold surface with its cover removed in order to view these LEDs.
1. System State LEDs Use the following table to interpret the LEDs.
2. CPU Error LEDs Use the following table to interpret the LEDs.
Platform Reset Normally remains on during standby. This LED flashes on (yellow) briefly at power-on. LED should turn off as system powers up and begins to execute instructions. Overtemp LEDs Normally off. These LEDs come on if an error occurs. If LED is solidly on, it may indicate a processor over-temperature condition. Initial processor over-temperature can cause symptoms such as sluggish computer performance. Chronic processor over-temperature can cause the computer to hang completely.
$Bx = 1 0 1 1 X X X X = All $Bx codes below are memory init codes (x may be any code 0 - F) $BF = 1 0 0 1 1 1 1 1 = If the unit does not progress past any $Bx memory init codes, this could indicate a memory issue regardless of whether DIMM diagnostic error LEDs are ON or not. $12 = 0 0 0 1 0 0 1 0 = After memory initialization has successfully completed $51 = 0 1 0 1 0 0 0 1 = Video driver enabled beyond this point. Attached display should be displaying an image now.
5 & 6. Memory Diagnostic LEDs (A1 - A6 and B1 - B6) This group of LEDs will normally remain OFF during power-on and throughout normal operation. If any of these LEDs come ON RED, this indicates that the corresponding DIMM (or its slot) may be faulty. To verify whether the fault lies with the DIMM or the slot, power down the unit and move the DIMM to another slot. If the DIMM is faulty, the LED adjacent to its new slot should come ON RED when power is reapplied.
7. Reset Buttons System Management Controller (SMC) Reset The System Management Controller (SMC) is a chip on the logic board that controls all power functions for the Xserve. If the Xserve is experiencing any power issue, resetting the SMC may resolve it.
5. Press the power button to start up the Xserve. Power ON / OFF Button Behaves exactly like the front panel power button, and can be used as an alternate way to turn the unit on and off if needed. Reset Buttons When pressed, resets CPUs regardless of what is currently running. This reset overrides all software processes and restarts the system. Use with caution as this form of reset may corrupt software or files on a drive.
bay and the controller has recognized this event. The LED will turn ON GREEN again when the corresponding drive module has been removed from its bay. Since there are only three drive bays, the fourth I/O channel and LED are not used and should remain ON GREEN during normal operation. When you power-on the system, you should see the following activity sequence on these LEDs: 2010-06-28 1. The entire group of eight LEDs should come ON solid GREEN when power is applied and remain on for a few seconds. 2.
