Page 126 You can replace or install hard drives while the Xserve is running; you do not need to shut down or open the Xserve first, but you may need to dismount the drive from the Xserve OS beforehand.
Page 127 Error-correcting code (ECC) Important: Apple recommends that you use Apple-approved FB-DIMMS. Other FB-DIMMs might degrade the performance of the Xserve. DIMMs from older Xserve systems are not compatible with this Xserve. Note: Before you purchase DIMMs other than those recommended by Apple, make sure that the memory manufacturer conforms to the Joint Electronic Device Engineering Council (JEDEC) specification.
Page 128: Power Supply Redundancy
The Xserve supports up to two power supply modules for redundancy. There are two power supply bays in the rear of the Xserve’s enclosure. You can replace or install a power supply from the back panel without removing the Xserve from the rack. If the Xserve has two power supplies, they are hot-swappable;...
Page 129: Power Supply Status Led
If the Xserve has two power supplies and no AC power is available to one of the power supplies, or if one of the power supplies has failed, that power supply’s status LED will illuminate SOLID RED.
Page 130 A mini-DVI to VGA display adapter (such as the one shown above) is included with the Xserve. The Xserve mini-DVI display port also supports other optional Apple video adapters, such as the Apple mini-DVI to DVI adapter, and the Apple mini-DVI to Video adapter.
Page 131: Selecting An Alternative Startup Method From The Front Panel
Selecting an Alternative Startup Method from the Front Panel You can use the Xserve’s front panel controls to choose from optional startup methods that might be helpful in special circumstances. To choose an alternative startup method from the front panel: With the power off, hold in the system identifier button while you press the on/standby button.
Page 132: Resetting The Logic Board
Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues in which the Xserve is unresponsive—in these situations, restarting the Xserve will generally suffice. If the Xserve isn’t responding, perform these steps one at a time, in the following order, until the issue has been resolved:...
Page 133: Power-On Self Test (Post) Error Indications
A power-on self test in the Xserve’s ROM automatically runs whenever the Xserve is started up after being fully shut down (the test does not run if the Xserve is only restarted). If the test detects a problem, the status LED located above the power button on the front of the Xserve will...
Page 134: Diagnostic Leds
Diagnostic LEDs The logic board includes three sets of LEDs to help service providers troubleshoot the Xserve: • System status LEDs (1 in the illustration below) • CPU status LEDs (2 in the illustration below) • EFI POST LEDs (3 in the illustration below) The LEDs are located toward the rear of the logic board.
Page 135: System Status Leds
System is powered on. DS9C3: SLEEP Important: The red DS9C3 LED warns that the Xserve is in sleep mode. When this LED is ON, do not remove or replace PCI expansion cards or FB-DIMMs, because the Xserve is still powered on.
Page 136 • If the LED is still on, power down the Xserve and try resetting the SMC. Restart the Xserve. • Reset the power supply by unplugging the AC cord for 20 seconds.
Page 137: Memory Diagnostic Leds
Memory Diagnostic LEDs The Xserve (Late 2006) logic board includes diagnostic LEDs for each FB-DIMM. Each of the LEDs will light if it detects an issue with the corresponding installed FB-DIMM. These LEDs will also flash briefly when the computer is started up or shut down and when it goes in and out of sleep mode.
Page 138: Power Supply Verification
If you cannot verify these LEDs are on, try replacing the power supply with a known-good one. If you are working with an Xserve with two power supplies, try removing one and test one at a time to determine which one may have the issue. Also try the same known-good power supply in each power supply bay, to see if the issue is related to a single bay or not.
