Mac Pro (Early 2009) General Troubleshooting — Common Reset Procedures 26 2010-09-27 Common Reset Procedures The following reset procedures are often helpful in troubleshooting Mac Pro issues. Resetting the System Management Controller (SMC) The System Management Controller (SMC) controls all power functions for the computer. If the computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including: • Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth • Handling system resets from various commands • Controlling the fans It is also recommended that the SMC be reset after a backplane board or processor board is replaced as part of a repair. Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues in which the computer is unresponsive—in these situations, restarting the computer will generally suffice. If the computer isn’t responding, perform these steps one at a time, in the following order, until the issue has been resolved: 1. Force Quit (Option-Command-Escape) 2. Restart (Control-Command-Power) 3. Force Shut Down (press the power button for 10 seconds) Resetting the SMC can resolve some computer issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth. If the computer still exhibits these types of issues after you’ve restarted the computer, try resetting the SMC by removing AC power: 1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off ). 2. Unplug the AC power cord. 3. Wait at least 15 seconds. 4. Plug the power cord back in, making sure the power button is not being pressed at the time. 5. Press the power button to start up the computer.

Mac Pro (Early 2009) General Troubleshooting — Common Reset Procedures 27 2010-09-27 Resetting the Parameter RAM (PRAM) To reset PRAM: 1. If the computer is on, turn it off. 2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in Step 4. 3. Turn on the computer. 4. Press and hold the Command-Option-P-R keys. Important: You must press this key combination before the gray screen appears. 5. Hold the keys down until the computer restarts and you hear the startup sound for the second time. 6. Release the keys. For more information: http://www.apple.com/support HT1379—Resetting your Mac’s PRAM and VRAM Starting Up in Safe Mode A Safe Boot is a special way to start Mac OS X when troubleshooting. To start up into Safe Mode (Safe Boot): 1. Make sure the computer is shut down. 2. Press the power button. 3. Immediately after you hear the startup tone, press and hold the Shift key. Note: The Shift key should be held as soon as possible after the startup tone but not before. 4. Release the Shift key when you see the screen with the gray Apple and progress indicator (looks like a spinning gear). During startup, ”Safe Boot” appears on the Mac OS X startup screen. To leave Safe Mode, restart the computer normally, without holding down any keys during startup. For more information: http://www.apple.com/support HT1564—What is Safe Boot, Safe Mode?

Mac Pro (Early 2009) General Troubleshooting — Power-On Self Test: RAM and Processor Verification 28 2010-09-27 Real Time Clock (RTC) Reset The Real Time Clock (RTC) is a chip on the backplane board that controls the date and time functions of the computer. If the computer is experiencing an issue booting, resetting the RTC may resolve it. Follow these steps to reset the RTC: 1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off ). 2. Unplug the AC power cord. 3. Remove the battery for at least 20 seconds. You may need to remove a PCI Express card to have access to the battery. Alternatively, you can reset RTC by pressing the RTC reset button (small button located next to the battery). Press the button for one second when the computer is shut down but still connected to AC power. Power-On Self Test: RAM and Processor Verification A power-on self test in the computer’s ROM automatically runs whenever the computer is started up after being fully shut down (the test does not run if the computer is only restarted). If the test detects a problem, the status LED located above the power button on the front of the computer will flash in the following ways*: • 1 Flash: No RAM is installed or detected. Or, the quick memory test failed. An LED will light up on the processor board next to the affected DIMM or empty DIMM slot. • 3 Flashes: A RAM bank failed extended memory testing. An LED will light up on the processor board corresponding to the affected DIMM. Troubleshooting: Try reseating the memory DIMMs. Check memory installation instructions for proper installation order. Swap affected DIMM with known good DIMM. *Note: The status LED lights up when the power button is depressed at startup. Do not count this light as one of the diagnostic flashes. The memory processor board diagnostic LEDs will also flash briefly when the computer is started up or shut down and when it goes in and out of sleep mode. This is normal behavior.
Mac Pro (Early 2009) General Troubleshooting — Minimum Configuration Testing 29 2010-09-27 Minimum Configuration Testing The following procedure can help you troubleshoot a “No Power” or other startup related symptom. Using this method of gradually building the system up from a bare minimum and verifying expected behaviors at each step is one way of determining which modules function together in some limited form. The goal is to identify which module(s) cause a symptom to recur when they are added. Alternatively, the method may help you discover a loose or faulty cable or connector. If you encounter unexpected behavior at a step, the general rule of thumb is to suspect the last module you re-installed. Backtrack to the previous step, remove the last installed module, and re-verify the expected behavior. Note: As with any troubleshooting method, minimum configuration testing is not practical for every repair. Refer to other troubleshooting sections provided in this manual for additional direction in troubleshooting. Take Mac Pro Down to Minimum Configuration 1. Remove the following items from the Mac Pro: • Hard drives • Optical drives • Processor tray and processor board (containing processors, processor heatsinks, and memory) • PCIe cards • AirPort card • Bluetooth card • Battery • PCIe fan • Processor cage (including fans) • Front panel board Disconnect all cables from the backplane board, except the power supply.
Mac Pro (Early 2009) General Troubleshooting — Minimum Configuration Testing 30 2010-09-27 2. Attach a known good power cord from a known good AC source to the Mac Pro. Note: When connecting the Mac Pro to AC power, verify that the LEDs for OVTMP CPUA and OVTMP CPUB briefly flash red (less than 0.5 sec). The LEDs are located under hard drive bay 1 on the backplane board. If they do not illuminate briefly, there is an issue with either the power supply or the backplane board. Generally speaking, power supplies, because of their nature, can be affected by issues more than other modules. If you suspect a power supply has failed,verify it in another Mac Pro (Early 2009), if available, before replacing any modules. Note: The OVTMP CPUA and OVTMP CPUB LEDs on a properly functioning Mac Pro will also momentarily flash red immediately after the Mac Pro is disconnected from AC power. 3. Press the DIAG button, and verify 5V STBY LED (amber) illuminates. Expected behavior: 5V STBY LED illuminates, confirming power to the backplane board. If the LED does not illumuniate, suspect power supply or backplane board failure. 4. Disconnect AC power cord. Reinstall processor cage with fans and processor board. Do not reinstall processor(s), heatsinks, or memory. Notes: • Verify no bent pins on processor connector or mating connector of processor board and backplane board. • Verify no grime or foreign debris is causing contact issues on processor connectors, and connectors on processor board and backplane board. 5. Connect AC power cord. Press the DIAG button to verify the 5V STBY LED illuminates. This is
