Xserve (Early 2009) Basics — Overview 11

Hot-Pluggable SATA or SAS Drives

The server includes three hard drive bays at the front of the Xserve. All bays support Apple qualied hot-pluggable Apple Serial ATA (SATA) or Serial Attached SCSI (SAS) drive modules. Xserve drive bays support qualied Apple Drive Modules with Apple qualied hard drives and rmware only. Drive bays not congured with an Apple Drive Module ship with a nonfunctional blank drive carrier which do not support third-party hard drive installation.

Drive bays are numbered 1-3, beginning with the far left bay. The drive installed in bay 1 is the boot drive and should have the operating system installed on it. Xserve’s congured with a Solid-State Drive (SSD) will contain the Mac OS X Server operating system and function as the boot drive.

You can replace or install hard drives while the Xserve is running; you do not need to shutdown or open the Xserve rst, but you may need to dismount the drive from the Xserve OS beforehand. A status light on the front of each drive indicates when it is safe to remove the drive without losing data. For more information, see “Apple Drive Module” in the Take Apart chapter.

Solid-State Drive

The server may include an optional Solid-State Drive. The drive contains the Mac OS X Server operating system as the boot drive for the Xserve.

Xserve (Early 2009) Basics — Overview 12

Power Supply Redundancy

The Xserve (Early 2009) supports up to two power supply modules for redundancy. There are two power supply bays in the rear of the 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; the Xserve will continue to operate using only one supply while the second is removed. For more information about removing or installing power supply modules, see “Power Supply” in the Take Apart chapter.

How to Identify Single- and Dual-Processor Congurations

To identify the conguration of an Xserve (Early 2009) computer, check the code on the computer’s ID Tab, which is located on the computer’s back panel. See “Serial Number

Location.”

There are three options for identifying single and dual processor congurations:

• Quad-Core Xserve (Early 2009): Single processor logic board with 6DIMM slots, and one large heat sink

• 8-Core Xserve (Early 2009): Dual processor logic board with 12 DIMM slots, and two large heat sinks:

• Quad-Core Xserve (Early 2009): Single processor logic board, 12 DIMM slots and one large heat sink. This option is present only when a single-processor logic board has previously been replaced via the Xserve service parts kit.

Xserve (Early 2009) General Troubleshooting — Update System Software 15

Xserve Firmware Updates

Firmware is the name given to software that is written into memory circuits, such as ash memory, that will hold the software code indenitely, 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 rmware is stored on the Xserve (Early 2009) backplane board. EFI rmware updates update the Boot ROM, and SMC updates update the System Management Controller rmware. The SMC manages fans and other environmental parameters that are independent of the Boot ROM.

Firmware symptoms can be easily mistaken for hardware issues (e.g., overheating issues, fan noise issues, etc.). Always check both EFI and SMC rmware versions and update if necessary before replacing any hardware components.

The following lists describe the type of symptoms that may be resolved by updating the EFI and SMC rmware.

Symptoms that may be resolved by updating EFI rmware:

• Cannot eject media (various conditions)

• No video on start up

• Not waking or sleeping when expected

• Bad media taking too long to eject (including holding mouse button down at startup taking minutes to eject)

Symptoms that may be resolved by updating SMC rmware:

• Fan related behavior (excessive speed or noise)

• Loud audible clicking from some fans

• Thermal shut down or warnings

• Diagnostics reporting failures

• Sleep/wake issues

• Intermittent shut down

• SMC causes bad/missing ambient sensor to cause the computer to go to sleep

• Hangs, black screen on restart from Windows

Please follow the steps outlined in KnowledgeBase article HT2013, “About Firmware Updates

for Xserve,” to perform an EFI and/or SMC rmware update. Information about rmware

versions for Intel Macs can be found in KnowledgeBase article HT1237, “Mac OS X: Firmware

Updates for Intel-based Macs.”

Memory Conguration

Xserve (Early 2009) comes with a minimum of 3 GB of 1066MHz DDR3 ECC memory, installed as three 1 GB unbuered dual inline memory modules (UDIMMs).

2010-06-28

Xserve (Early 2009) General Troubleshooting — Xserve Firmware Updates 16

DIMMs must t these specications:

• 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. You can install 1 GB, 2 GB or 4GB DIMMs for a total of up to 24 GB of memory.

You can install dierent size DIMMs in Xserve (Early 2009). However, for best performance, Apple recommends you install equal-size DIMMs (all 1, 2 or 4GB) lling the slots in the order listed in this table.

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. Most internal diagnostic LEDs are only enabled to come on when the cover is removed (memory DIMM LEDs remain ON even with the cover in place).

• Do not attempt to troubleshoot the unit solely by these LEDs alone. Use this information to

guide your troubleshooting, not lead it.

If a specic error condition exists, there should be corresponding LED evidence to help verify and isolate the issue. However, it is not possible to deduce a fault or isolate a specic symptom solely by examining these LEDs out of context.

Platform Reset

Normally remains on during standby. This LED ashes on (yellow) briey at power-on. LED should turn o as system powers up and begins to execute instructions.

Overtemp LEDs

Normally o. 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.

Troubleshooting:

• Verify proper heatsink installation.

• Verify all fans are operating properly, especially the fan array.

• If both overtemp LEDs come on immediately when the computer is turned on, a faulty power supply could be one cause of this behavior. Replace power supply.

• Try swapping CPU A and CPU B locations. If the CPU Error LED follows the CPU, replace that CPU.

3. EFI POST (Power On Self Test) LEDs

This group of eight LEDs are arranged into two sets of four LEDs, representing a binary code that only has any signicance during the short time between power-on and the unit begins to boot the OS, while the CPU is executing EFI code only. At no other time should these LEDs be used or interpreted to mean anything meaningful.

The code is more easily described as two Hexadecimal digits ranging from $00 to $FF, to make it easier to list and compare during troubleshooting. Each ONE represents an LED that is ON, and each ZERO represents an LED that is OFF

Normal power-up LED sequence:

• The sequence of codes below is typical in the rst few seconds of a functioning unit’s boot

cycle, immediately following power-on, during the EFI phase of startup.

• If your system is not booting you should check these LEDs closely to verify the sequence of

codes has been executed in addition to your normal troubleshooting steps. Each code will only remain ON GREEN for a split-second each. The entire sequence takes only a few seconds to progress through.

• To see this sequence, power-on the unit (use the remote power on/o button on the logic

board) while holding down the option key on an attached USB keyboard, to invoke the EFI startup manager and prevent the unit from leaving EFI and booting into any OS. Do this as you watch these LEDs as they progress through the following sequence:

2010-06-28

Begin (power-on)

Xserve (Early 2009) General Troubleshooting — Diagnostic LEDs 25

$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. If not, this may indicate a graphics card issue.

$F9 = 1 1 1 1 1 0 0 1 = EFI nished and passed on control to OS boot loader

4. CPU Voltage LEDs

This group of LEDs will normally FLASH RED briey during power-on, then should normally remain ON solidly GREEN when all voltage regulators are functioning properly to provide voltages to CPU A and CPU B, as well as IOH.

If any of these LEDs remain ON RED, this indicates that the corresponding voltage regulator is enabled but not providing any voltage output.

2010-06-28

In single processor units the LED group for the second processor are not present.

Xserve (Early 2009) General Troubleshooting — Diagnostic LEDs 26

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. If a known-good DIMM is installed in the suspect slot and the LED adjacent to this slot should come ON RED , this may indicate a faulty DIMM slot on the logic board.

2010-06-28

How to Troubleshoot Memory LEDs

1. Remove and reseat DIMM

2. Restart computer. If associated LED is no longer illuminated, issue is resolved

3. If associated LED remains illuminated, replace DIMM with new DIMM

4. Restart computer and verify LED is no longer illuminated

Xserve (Early 2009) General Troubleshooting — Diagnostic LEDs 27

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. The SMC controls several functions, including:

• Telling the Xserve when to turn on, turn o, sleep, wake, idle, and so forth

• Handling system resets from various commands

• Controlling the fans

It is also recommended that the SMC be reset on any new logic board after it is installed 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 Xserve is unresponsive—in these situations, restarting the Xserve will generally suce.

If the Xserve 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)

4. Remove the Xserve from the rack (if applicable)

5. Remove the Top Case

6. Press the SMC Reset button on the logic board

Resetting the SMC can resolve some Xserve issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth. If the Xserve still exhibits these types of issues after you’ve restarted the Xserve, try resetting the SMC. There are two ways to reset the SMC on the Xserve.

System Management Control (SMC) Reset in Rack

1. Shut Down the Xserve, either locally or using remote commands (or if the Xserve is not

responding, hold the power button until it turns o).

2. Unplug the AC power cord.

2010-06-28

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.

Xserve (Early 2009) General Troubleshooting — Diagnostic LEDs 28

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 o 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 les on a drive.

2010-06-28

Drive Interconnect Backplane LEDs

Note: The following information describes the diagnostic LEDs present on the interconnect backplane.

This group of eight LEDs are arranged into two sets of four LEDs, representing information about the SATA / SAS communication between the drive controller channels on the drive interconnect backplane and the drive modules themselves. The optional SSD drive does not have a representative LED on this board.

There is also a ‘heartbeat’ LED on this board which starts ashing ON GREEN and OFF when EFI loads immediately after power-on and continues to ash ON and OFF during normal operation.

The rst group of four LEDs indicates activity for the four I/O channels corresponding to the three drive bays. Since there are only three drive bays, the fourth I/O channel and LED are not used and should remain OFF during normal operation.

The second group of four LEDs indicates that the controller has recognized that a drive module is present and connected. These LEDs are normally solidly ON GREEN when no drive is present, and turn OFF when a drive module has been inserted into the corresponding drive

Xserve (Early 2009) General Troubleshooting — Diagnostic LEDs 29

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:

1. The entire group of eight LEDs should come ON solid GREEN when power is applied and

remain on for a few seconds.

2. The heartbeat LED begins ashing when EFI loads in the rst few second after power-on.

The rst group of four activity LEDs should now turn OFF. The second group of four ‘drive present’ LEDs should remain on for a few more seconds.

3. The second group of four ‘drive present’ LEDs should each turn OFF as the controller scans

and recognizes each connected drive module in turn, from bay 1 to bay 3 in order. The fourth LED should remain ON since no drive is present on the fourth I/O channel.

4. Beyond this point, the only LEDs that should be ashing are among the rst group of four

drive activity LEDs, to indicate drive activity between a corresponding drive module, such as the boot drive module booting the OS, and the drive controller.

Quick Check

Symptom Quick Check

No Power / Dead Unit

• No fan or drive module spin

• No LED activity

1. Check the front panel on/standby light. This light should be solid white when the Xserve is running, and o when the Xserve is in standby mode. If it’s ashing white, the Xserve is in sleep mode.

2. Verify the power outlet and power cord are known good and that AC power is present.

3. Check the power supply status light next to the power cord connector on the rear of the Xserve (check the LEDs for both supplies in a twopower-supply conguration).

4. Solid green indicates power is available and Xserve should be on.

5. Blinking green indicates AC power is available but power to the Xserve components from this supply is on standby (usually because the Xserve is turned o).

6. Red indicates either no AC power is available to this supply from the power cord or this power supply has failed.

7. Disconnect all external cables such as network, peripheral, and expansion card connections, and press the power button again.

Burnt Smell or Odor

Quick Check

Symptom Quick Check

Burnt Smell / Odor

• System emits an odor or smell of smoke.

1. Disconnect the power cord from the system.

2. Identify the source of the odor.

3. Some odors may be present when operating

normally. Refer to http://support.apple.com/kb/

TA22044.

Some visual clues may include brown marks on PCBs, and component damage i.e. transistors, ICs, inductors, capacitors, resistors etc.

When certain components fail because of overheating the smell or odor clues may not be evident after the time of the incident.

Some components may not be easily accessible for visual identication of possible failure.

Important Note: Components may emit a brief noncontinuous smoke or odor when the failure occurs. However this does not typically suggest a safety issue, however a thorough inspection should be made. During inspection you feel there may a safety issue with the System please notify Apple through the appropriate escalation routes.

RAID Battery Not Charging

Quick Check

Symptom Quick Check

RAID Battery Will Not Charge

• The following messages may be displayed in RAID Utility:

The Apple RAID Card Installed in your system requires your attention:

Write Caches Disabled, and/ or RAID Battery Conditioning:

RAID Battery Missing:

• The RAID battery status never achieves ‘Charged’ status:

• Normal ‘Charged’ Status:

1. If write caches are disabled: The RAID card backup battery may not be fully charged. To protect your data, the RAID card automatically disables write caching whenever the battery is not fully charged. Once every three months the RAID card reconditions the battery by completely discharging and then recharging it.

2. If the battery is not fully charged: Every three months, the RAID card automatically reconditions its battery by completely discharging and then recharging it. During the reconditioning cycle, you may see an alert advising you that the 72hour battery reserve is unavailable and the controller status may indicate that write caches are disabled. Performance may be slightly degraded during this time, but will return to normal when the battery is fully recharged.

3. In most cases, leaving the Xserve powered ON continuously for 72 hours or more (not in Standby and not in Sleep mode, but actually powered ON without interruption) gives the charging system sucient time to fully charge the battery and restore the write caches to full functionality.

4. Examine Xserve log les for clues and run complete AXD diagnostics on the Xserve to gather more information before continuing to the Deep Dive section of this symptom.
