The following topics are covered in this chapter:

Section 4.1, Tools and Supplies Needed

Section 4.2, Removing the Server Module From the Chassis and Removing the Cover

Section 4.3, Locations of Replaceable Components

Section 4.4, Replaceable Component Procedures

4.1 Tools and Supplies Needed

You can service the server with the following items:

No. 2 Phillips screwdriver

Adjustable-setting torque driver (5-20 in.-lbs)

Antistatic wrist strap

Stylus, or other pointed object (to press the recessed Power button)

Long-nosed pliers (optional for service processor [SP] board removal)

4.2 Removing the Server Module From the Chassis and Removing the Cover

Use the preparatory procedures in this section when you are referred to them from the removal and replacement procedures.

Caution - Do not operate the system with empty slots. Always insert a filler into an empty slot to reduce the possibility of module shut down.

4.2.1 Removing the Server Module From the Chassis

To replace components for the Sun Blade X6220 server module, with the exception of the hard drives, you need to remove the server module from the chassis. If you are only removing hard drives, you can skip this section and go to Section 4.4.1, Replacing a Hard Disk Drive.

1. Choose a method for shutting down the server from main power mode to standby power mode.

See FIGURE 1-1 for the location of the power button.

Graceful shutdown: Use a stylus, or other pointed object, to press and release the recessed Power button on the front panel. This causes Advanced Configuration and Power Interface (ACPI) enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems shut down to standby power mode immediately.

ILOM shutdown: Use the ILOM CLI or Web GUI to power off the system.

At the ILOM command prompt, type:

stop /SYS

See the Integrated Lights Out Manager Administration Guide for ILOM 1.1.1,
820-0280, for more information.

When the main power is off, the Power/OK LED on the front panel begins flashing, indicating that the server is in standby power mode.

Note - When you use the Power button to enter standby power mode, power is still directed to the SP board and power supply fans, indicated when the Power/OK LED is flashing. To completely power off the server, you must remove the server module from the midplane.

2. Turn off any peripheral devices connected to the dongle, and disconnect the dongle from the server.

3. Remove the server module from the chassis. See FIGURE 4-1.

a. Press together and hold green ejector buttons.

b. Open the ejector levers by rotating them out from the server module.

c. Pull the server module out from the chassis by the ejector levers until you are able to grasp the module with both hands to pull it out of the chassis.

4. Set the server module on an antistatic surface.

5. Install a filler panel into the server module slot if the server module will be out of the chassis for more than one minute.

Caution - Before handling internal components of the server module, attach an electrostatic-discharge (ESD) wrist strap to the grounding post that is built into the rear of the chassis. The system's printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity.

4.2.2 Removing the Main Cover

1. Press down on the cover release button and, using the indent for leverage, slide the main cover toward the rear of the chassis approximately 0.5 inch (12 mm). See FIGURE 4-2.

2. Grasp the cover by its rear edge and lift it straight up from the chassis.

Diagram showing the locations of the replaceable server module components.

4.4 Replaceable Component Procedures

Note - Some of the procedures in this section are for customer-replaceable units (CRUs) and some are for field-replaceable units (FRUs), as noted in the procedures and in the list below. FRU components should be replaced only by trained service technicians. Contact your Sun Service representative for assistance with FRU replacements.

This section contains procedures for replacing the following components:

Section 4.4.1, Replacing a Hard Disk Drive (CRU)

Section 4.4.2, Replacing the Battery (CRU)

Section 4.4.3, Replacing the Compact Flash Module(CRU)

Section 4.4.4, Replacing Memory Modules (DIMMs) (CRU)

Section 4.4.5, Replacing the SP Board (CRU)

Section 4.4.6, Replacing a CPU and Heatsink (FRU)

Section 4.4.7, Replacing the Motherboard (FRU)

Caution - Before handling components, attach an ESD wrist strap to the grounding post that is built into the rear of the chassis. The system's printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity.

4.4.1 Replacing a Hard Disk Drive

Follow these steps to remove and replace a hard disk drive (HDD).

Note - This component is a hot-swappable CRU and can be replaced by anyone.

The internal system software designation of the HDDs is shown in FIGURE 4-4.

FIGURE 4-4 Designation of Hard Disk Drives

System designation of hard disk drives, as seen from the system front

A single HDD failure does not cause a data failure if the HDDs are configured as a mirrored RAID 1 volume (optional). The HDD can be hot-swapped, and when a new HDD is inserted, the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If the bad HDD was configured as a hotspare, the new HDD is automatically configured as a new hotspare.

Caution - Possible data loss: If you insert an HDD that has been configured with a RAID volume into a server that did not previously have its HDDs configured with RAID volumes, the existing HDDs in the server will be converted to RAID volumes during automatic synchronization and any existing data on the existing HDDs in the server are erased. Before permanently removing an HDD that is part of an active RAID volume, use the MegaRAID Storage Manager-Integrated RAID (MSM-IR) to delete the RAID volume from the HDD to avoid causing this problem.

For information about the implementation of RAID on this server and instructions on how to use the MSM-IR (MegaRAID Storage Manager-Integrated RAID) utility to create RAID arrays and then manage and monitor the RAID arrays, refer to the X64 Servers Utilities Reference Manual, 820-1120.

Supported components and their part numbers are subject to change over time. For the most up-to-date list of replaceable components for these servers, see the following URL:

http://sunsolve.sun.com/handbook_pub/Systems/

1. Click the name and model of your server.

2. On the product page that opens for the server, click the Full Components List for the list of components.

Use the following procedure to replace this component.

1. Observe the LEDs on the faces of the HDDs and identify the defective HDD:

Middle LED on (amber): The drive is faulty and should be replaced.

Left LED on (green): The drive is operating properly.

2. Execute the software commands appropriate to the software that you are using to prepare the hard drive for removal.

Caution - Do not operate the system with empty slots. Always insert a filler into an empty slot to reduce the possibility of module shut down.

The Sun Blade X6220 server module HDDs are hot-swappable, so you can remove an HDD either when the server module is installed in the chassis or when it is out of the chassis. See FIGURE 4-5 and FIGURE 4-6.

FIGURE 4-5 Removing the Hard Disk Drive After Removing the Server Module

Figure showing hard disk drive removal when server module is removed from chassis

FIGURE 4-6 Removing the Hard Disk Drive Without Removing the Server Module

Figure showing hard disk drive removal when server module is installed in chassis

Note - When you return the HDDs in their bays, you must return each HDD to the same bay from which it was removed. Use an adhesive note or another method to temporarily label the HDDs when you remove them.

3. Press the button on the face of the HDD to release the spring-loaded securing latch. See FIGURE 4-5 and FIGURE 4-6.

4. Grasp the securing latch and remove the HDD from the drive bay.

Installation is the reverse of the foregoing procedure.

Note - If the HDDs were previously configured as a mirrored RAID 1 array, an automatic resynchronization is invoked and the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If the bad HDD was configured as a hotspare, the new HDD is automatically configured as a new hotspare.

Note - When you install an HDD, open its securing latch before you push the drive into the bay. Push the HDD into the bay until it stops, and then close the securing latch to fully engage the connector on the HDD backplane.

4.4.4 Replacing Memory Modules (DIMMs)

Use the procedures in this section to remove and replace the server's dual inline memory modules (DIMMs).

4.4.4.1 DIMM Population Rules

The DIMM population rules for the Sun Blade X6220 server modules are listed here:

Each CPU can support a maximum of eight DDR2 DIMMs.

Each pair of DIMMs must be identical (same manufacturer, size, and speed).

The DIMM slots are paired and the DIMMs must be installed in pairs. The memory sockets are colored black or white to indicate which slots are paired by matching colors.

Populate the DIMMs in the slots farthest from the CPU first. The first pair to be populated should be D7/D6, then D5/D4, and so on.

Note - This component is a CRU and can be replaced by anyone.

Supported components and their part numbers are subject to change over time. For the most up-to-date list of replaceable components for these servers, see the following URL:

b. Align the notch in the bottom edge of the DIMM with the key in the DIMM socket. See FIGURE 4-11.

c. Press down evenly on both top corners of the DIMM until the ejectors snap over the cutouts in the left and right edges of the DIMM.

4.4.4.3 Error Correction and Parity

The AMD dual-core processor on the Sun Blade X6220 server module provides parity protection on its internal cache memories and error-correcting code (ECC) protection of the data. The system can detect and log to the system event log (SEL) the following types of errors:

Correctable and uncorrectable memory ECC errors

Correctable and uncorrectable CPU internal errors

Faults in the chassis shared infrastructure, including fan and power supply faults

Advanced ECC corrects up to 4 bits in error on nibble boundaries, as long as they are all in the same DRAM. If a DRAM fails, the DIMM continues to function.

Refer to the Integrated Lights Out Manager Administration Guide for ILOM 1.1.1,
820-0280, for more information on accessing the error log.

4.4.5 Replacing the SP Board

The service processor (SP) board is sometimes referred to as the graphics redirect and service processor (GRASP) board.

FIGURE 4-17 Required Pattern for Thermal Grease Application

Figure showing required pattern for thermal grease application on the CPU surface

b. If you are reinstalling an existing heatsink, use an alcohol pad to clean all the old thermal grease from the component surface. Also, clean the dust from the heatsink fins.

Note - System cooling might be affected by dust and contaminant build-up. Therefore, you should open and check systems approximately every six months (or more often in dirty operating environments). Check system heatsinks, fans, and air openings. If necessary, clean systems by carefully brushing, blowing, or vacuuming contaminants from the system.

c. Turn the heatsink upright and reinsert the four springs and mounting screws.

Caution - Avoid moving the heatsink after it has contacted the top of the CPU. Too much movement could disturb the layer of thermal grease, leading to component damage.

d. Carefully position and align the heatsink over the CPU.

Note - The heatsink is not symmetrical, and it must be aligned before you place it on the CPU. Note that the half of the Sun Microsystems logo imprinted on the top of the heatsink creates a complete logo when correctly aligned with the adjacent heatsink.

e. Lower the heatsink onto the CPU, aligning the mounting screws with their holes on the motherboard.

f. Using an adjustable torque driver, alternately tighten the two heatsink mounting screws, 180 degrees at a time, until each spring is completely compressed.

Tighten the screws to 7 in.-lbs (0.8 Nm).
