Removal and Replacement Procedures

This chapter provides subassembly/module-level removal and replacement procedures for the HP ProLiant ML150 G2 Server.

To service the server, a T-15 Torx screwdriver may be needed.

HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide 2-1

Removal and Replacement Procedures

Electrostatic Discharge Information

An electrostatic discharge (ESD) can damage static-sensitive devices or microcircuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions:

• Transport products in static-safe containers such as conductive tubes, bags, or boxes.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free

stations.

• Cover workstations with approved static-dissipating material. Use a wrist strap connected

to the work surface, and properly grounded (earthed) tools and equipment.

• Keep work area free of nonconductive materials, such as ordinary plastic assembly aids

and foam packing.

• Make sure that you are always properly grounded (earthed) when touching a

static-sensitive component or assembly.

• Avoid touching pins, leads, or circuitry.

• Always place drives with the Printed Circuit Board (PCB) assembly-side down.

• Use conductive field service tools.

Symbols on Equipment

These symbols may be located on equipment in areas where hazardous conditions may exist.

WARNING: This symbol, in conjunction with any of the following symbols, indicates the presence of a potential hazard. The potential for injury exists if warnings are not observed. Consult your documentation for specific details.

This symbol indicates the presence of hazardous energy circuits or electric shock hazards. Refer all servicing to qualified personnel.

WARNING: To reduce the risk of injury from electric shock hazards, do not open this enclosure. Refer all maintenance, upgrades, and servicing to qualified personnel.

This symbol indicates the presence of electric shock hazards. The area contains no user or field serviceable parts. Do not open for any reason.

WARNING: To reduce the risk of injury from electric shock hazards, do not open this enclosure

This symbol on an RJ-45 receptacle indicates a network interface connection. WARNING: To reduce the risk of electric shock, fire, or damage to the equipment, do

not plug telephone or telecommunications connectors into this receptacle.

This symbol indicates the presence of a hot surface or hot component. If this surface is contacted, the potential for injury exists.

WARNING: To reduce the risk of injury from a hot component, allow the surface to cool before touching.

These symbols, on power supplies or systems, indicate that the equipment is supplied by multiple sources of power.

WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system.

This symbol indicates that the component exceeds the recommended weight for one individual to handle safely.

Weight in kg Weight in lb

WARNING: To reduce the risk of personal injury or damage to the equipment, observe local occupational health and safety requirements and guidelines for manual material handling.

Removal and Replacement Procedures

HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide 2-3

Removal and Replacement Procedures

Preparation Procedures

WARNING: Only authorized technicians trained by HP should attempt to repair this equipment. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.

CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that

you are properly grounded (earthed) before beginning any installation procedure. Refer to “Electrostatic Discharge Information” earlier in this chapter for more information.

Before removing any serviceable parts, determine whether the part is hot-pluggable or non-hot-pluggable.

Non-Hot-Pluggable Device

If the device is non-hot-pluggable, the server must be powered down. Non-hot-pluggable devices in the server include the processor, all boards, memory modules, fans, PCI option cards and drive cages.

Powering Down the Server

WARNING: To reduce the risk of injury from electric shock, disconnect all power cords to completely remove power from the system.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching them.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a

regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes, and keeps the system in operation during a power failure.

CAUTION: The server must always be operated with system unit covers on. Proper cooling is not achieved when the system unit covers are removed.

2-4 HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide

Removal and Replacement Procedures

To power down the server:

1. Shut down the operating system in an orderly manner as directed in the operating system instructions.

2. If the server is on, press the power button to power down the server. If you are unable to shut down the server normally, press and hold the power button for

more than four seconds to power down the server.

3. Be sure that the power indicator on the front panel is off and that the fan noise has stopped.

4. Disconnect the AC power cord from the AC outlet, and then from the server.

5. Disconnect all external peripheral devices from the server.

Removal and Replacement Procedures

NOTE: When connecting the SATA data cables, be sure to connect them in the following order:

• The connectors on the SATA card from left to right: white, yellow, green, blue.

• The connectors on the SATA backplane from top to bottom: white, yellow, green; blue on the

bottom right corner.

NOTE: There are two SATA LED cables which are tied together using a cable tie. When connecting the SATA LED cables, be sure to connect them in the following way:

• The two cables should connect to the J14 (hard drive activity indictor) and J15 (hard drive status

indicator) connectors on the SATA card.

• The cable with one end to the J14 connector on the SATA card should connect to the J505

connector on the SATA backplane.

• The cable with one end to the J15 connector on the SATA card should connect to the J507

connector on the SATA backplane.

NOTE: You can upgrade by purchasing an HP 6-Port SATA RAID Controller option kit. When installing the 6-Port SATA RAID Controller, plug the I2C cable into the 3-pin connector labeled

J516 on the SATA backplane. Insert the cable by aligning pin 1 on the cable with pin 1 of connector J516. For detailed information on how to install the card, refer to the 6-Port SATA RAID controller User Guide.

Drive Bay Configuration

The server supports a maximum of nine drive bays (three are for removable media devices; six are for hot-plug hard drives). The removable media device bays contain a 3.5-inch

1.44-MB diskette drive; a 5.25-inch IDE optical device; and an empty drive bay.

2-16 HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide

Boot Priority

The server’s boot order should be considered when selecting a boot device. This is especially important if you are installing a board that requires a higher priority in the boot order. The board’s boot priority is set by its slot location in the boot order.

By default, the server searches for boot devices in the following order:

1. Legacy Floppy Drives (for the flexible diskette drive or virtual floppy)

2. USB FDD: (for the external USB floppy diskette drive)

3. IDE 0: (for the IDE CD-ROM drive)

4. USB HDD: (for the external USB hard disk drive or flash disk)

5. USB CDROM: (for the external USB CD-ROM drive)

6. SCSI/SATA: (for the SCSI or SATA hard disk drive)

7. PXE: (for the embedded LAN)

8. (reserved for additional boot devices)

NOTE: The boot order can be changed using the server’s BIOS Setup Utility.
