•
Safety Considerations
2
Before performing service procedures, review the following safety information.
Electrostatic Discharge
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To
prevent electrostatic damage:
•
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.
Be sure that you are properly grounded (earthed) when touching a static-sensitive
•
component or assembly.
Avoid touching pins, leads, or circuitry.
•
Use nonconductive field service tools.
•
HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide 2-1
Removal and Replacement Procedures
Symbols on Equipment
These symbols may be located on equipment in areas where hazardous conditions may exist.
Any product or assembly marked with these symbols indicates that the
component exceeds the recommended weight for one individual to handle safely.
66 kg
160 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.
Any surface or area of the equipment marked with these symbols indicates the
presence of a hot surface or a hot component.
WARNING: To reduce the risk of injury from a hot component, allow the surface
to cool before touching it.
Any surface or area of the equipment marked with these symbols indicates the
presence of electrical shock hazards. The enclosed area contains no
operator-serviceable parts.
WARNING: To reduce the risk of injury from electrical shock hazards, do not
open this enclosure.
Any RJ-45 receptacle marked with these symbols 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.
Rack Warnings and Cautions
WARNING: To reduce the risk of personal injury or damage to the equipment,
adequately stabilize the rack before extending a component outside the rack. Extend
only one component at a time. A rack may become unstable if more than one
component is extended.
WARNING: To reduce the risk of personal injury or damage to the equipment:
• Extend the leveling jacks to the floor.
• Rest the full weight of the rack on the leveling jacks.
• Attach the stabilizers to the rack, if it is a single rack installation.
• Couple the racks together in multiple rack installations.
WARNING: When installing the server in a telco rack, adequately secure the rack frame
to the building structure at the top and bottom.
2-2 HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide
WARNING: To reduce the risk of personal injury or damage to the equipment, use two
or more people to safely unload the rack from the pallet. An empty 42U rack weighs
115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become unstable when moved on its
casters. Handle the rack from both sides as it rolls down the ramp from the pallet. Do
not stand in front of the rack.
CAUTION: Always begin by mounting the heaviest item on the bottom of the rack. Continue
to populate the rack from the bottom to the top.
Server Warnings and Cautions
WARNING: Do not exceed the level of repair specified in the procedures in the product
documentation. All troubleshooting and repair procedures are detailed to allow only
subassembly or module-level repair. Because of the complexity of the individual
boards and subassemblies, do not attempt to make repairs at the component level or to
make modifications to any printed wiring board. Improper repairs can create a safety
hazard.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the hot-plug
drives and the internal system components to cool before touching.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the AC power cord grounding plug. The grounding plug is an
important safety feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily
accessible at all times.
• Unplug the power cord from each power supply to disconnect power to the
equipment.
WARNING: Before lifting the server, remove all hot-plug power supplies and hard
drives to reduce weight.
WARNING: The installation of internal options and routine maintenance and service of
this product should be performed by individuals who are knowledgeable about the
procedures, precautions, and hazards associated with equipment containing
hazardous energy levels.
WARNING: Do not use conductive tools that could bridge live parts. Remove all
watches, rings, or loose jewelry when working in hot-plug areas of an energized server.
WARNING: Do not replace non-hot-pluggable components while power is applied to
the product. First, shut down the product and disconnect all AC power cords.
Removal and Replacement Procedures
HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide 2-3
Removal and Replacement Procedures
WARNING: Be sure that the AC power supply branch circuit that provides power to the
rack is not overloaded. Maintaining a low electrical current draw reduces the risk of
personal injury, fire, or damage to the equipment. The total rack load should not
exceed 80 percent of the branch circuit rating. Consult the electrical authority having
jurisdiction over your facility for wiring and installation requirements.
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: Do not operate the server for extended periods without the access panel.
Operating the server without the access panel results in improper airflow and improper cooling
that can lead to thermal damage.
CAUTION: Reinstall each hard drive into the specific slot from which it was removed. Mixing
the hard drives adversely affects the system drive configuration.
Accessing Server Components
In order to access components in the server, any or all the following procedures may be
required:
Extending the server from the rack
•
Opening the hot-plug door
•
Removing the front bezel door (tower model only)
•
Removing the rack bezel (rack model only)
•
Removing the access panel
•

HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide 2-17
Removal and Replacement Procedures
Additional Requirements for Single-Board Mirrored Memory Technology
In addition to the DIMM configuration requirements for advanced ECC memory, observe the
following DIMM configuration requirements when installing DIMMs for single-board
mirrored memory:
•
Bank C mirrors bank A, and bank D mirrors bank B. Banks A and C must always be
populated.
•
DIMMs in the mirrored banks must be configured identically to the banks they are
mirroring. Corresponding banks (for instance, bank A and bank C) must be populated
with DIMMs of the same capacity.
Additional Requirements for Hot-Plug Mirrored Memory Technology
In addition to the DIMM configuration requirements for advanced ECC memory, observe the
following DIMM configuration requirements when installing DIMMs for hot-plug mirrored
memory:
•
Two memory boards must be installed.
•
Both memory boards must be configured identically. Corresponding banks (for instance,
bank A on the memory board in slot 1 and bank A on the memory board in slot 2) must
be populated with DIMMs of the same capacity.
Removing a Memory Board
CAUTION: Electrostatic discharge can damage electronic components. Make sure you are
properly grounded before beginning any installation procedure.
To remove a memory board:
1. If the server is not configured for hot-plug mirrored memory, you must power down the

SCSI Hard Drives
Be aware of the following guidelines cautioning unsafe hot-plug hard drive replacement.
•
Do not remove a degraded drive if any other member of the array is offline (the online
LED is off). No other drive in the array can be hot-plugged without data loss. The
exception to this is the use of RAID 1+0 as a fault-tolerant configuration. In this case,
drives are mirrored in pairs. More than one drive can fail and be replaced as long as the
drive or drives they are mirroring are online.
•
Do not remove a degraded drive if any member of an array is missing (previously
removed and not yet replaced).
Do not remove a degraded drive if any member of an array is being rebuilt, unless the
•
drive being rebuilt has been configured as an online spare. The online LED for the drive
flashes green or amber, indicating that a replaced drive is being rebuilt from the data
stored on the other drives.
NOTE: An online spare drive does not activate and start rebuilding after a predictive failure alert
because the degraded drive is still online. The online spare activates only after a drive in the array
has failed.
2-30 HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide
Removal and Replacement Procedures
• Do not replace multiple degraded drives at the same time, since the fault tolerance can be
compromised. When a drive is replaced, the controller uses data from the other drives in
the array to reconstruct data on the replacement drive. If more than one drive is removed,
a complete data set is not available to reconstruct data on the replacement drive or drives,
and permanent data loss can occur.
CAUTION: Do not turn off any external unit when the server containing the Smart Array
Controller is powered up. Also, do not power up the server before powering up the drive
enclosure. If these ordering rules are not followed, the Smart Array Controller may mark
the drives in this enclosure as “failed,” resulting in permanent data loss.
To remove a hard drive:
1. Open the front bezel door (tower model only). Refer to “Removing the Front Bezel Door
(Tower Model Only)” in this chapter.
CAUTION: Remove or replace a hard drive only when the drive failure LED is amber.
Data loss can occur if a drive is removed when the drive online LED is green. Refer to
“Hot-Plug Drive LEDs” in Chapter 4 for more information.
CAUTION: Remove or replace only one hard drive at a time. The controller relies on
other drives to reconstruct data on the replaced drive. Drive reconstruction is active when
the drive online LED is flashing green.
2. Push the sliding release button (1).
3. Swing out the ejector lever (2).
4. Pull the drive out from the drive cage (3).
CAUTION: Always populate drive bays with either a hard drive or blank. Proper airflow
can only be maintained when the bays are populated. Unpopulated drive bays can lead to
improper cooling and thermal damage.

PCI and PCI-X Hot Plug Expansion Boards
CAUTION: Do not attempt a PCI Hot Plug procedure if the operating system does not
provide PCI Hot Plug support or if you do not have the appropriate device drivers installed.
Failure to take these precautions causes system shutdown and risks data integrity.
CAUTION: To avoid critical errors, do not open the expansion slot latch if the green power
LED is on or blinking. Use the PCI Hot Plug button or the software application to turn off
power to the slot.
Use either the PCI-X Hot Plug button on the server or the operating system’s PCI-X Hot Plug
Utility to control the PCI-X Hot Plug slots.
• • The PCI-X Hot Plug button and the PCI-X Hot Plug Utility enable you to power up or
power down a PCI-X Hot Plug expansion slot. The PCI-X Hot Plug button enables direct
access at each hot-plug expansion slot.
PCI Hot Plug software support for each operating system is available online. For more
information, refer to the PCI Hot Plug Administrator’s Guide on the Documentation CD.
