Removal and Replacement Procedures
This chapter provides subassembly/module-level removal and replacement procedures for
ProLiant ML530 Generation 2 servers. After completing all necessary removal and
replacement procedures, run the Diagnostics program to be sure that all components operate
properly.
You need the following items for some procedures:
Torx T-15 tool
Torx T-10 tool
Diagnostics Utility from the HP SmartStart for Servers CD
Safety Considerations
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.

Removal and Replacement Procedures
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 electrical 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-plug components while power is applied to the
product. First, shut down the product and disconnect all AC power cords.
WARNING: Be sure that the AC power supply branch circuit that provides power to the
rack is not overloaded. Maintaining a low electric 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.

Removal and Replacement Procedures
Hot-Plug SCSI Hard Drives
Observe the following guidelines for hot-plug hard drive replacement.
Do not remove a degraded hard drive if any other member of the array is offline (the
online LED is off). No other hard 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, hard drives are mirrored in pairs. More than one hard drive can fail and be replaced
as long as the hard drive or hard drives they are mirroring are online.
Do not remove a degraded hard drive if any member of an array is missing (previously
and not yet replaced).
Do not remove a degraded hard drive if any member of an array is being rebuilt, unless
the hard drive being rebuilt has been configured as an online spare. The online LED for
the hard drive flashes green or amber, indicating that a replaced hard drive is being
rebuilt from the data stored on the other drives.
NOTE: An online spare hard drive does not activate and start rebuilding after a predictive failure
alert because the degraded hard drive is still online. The online spare activates only after a hard
drive in the array has failed.
Do not replace multiple degraded hard drives at the same time, since the fault tolerance
can be compromised. When a hard drive is replaced, the controller uses data from the
other hard drives in the array to reconstruct data on the replacement hard drive. If more
than one hard drive is removed, a complete data set is not available to reconstruct data on
the replacement hard 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 hard
drive enclosure. If these ordering rules are not followed, the Smart Array Controller may
mark the hard drives in this enclosure as “failed,” resulting in permanent data loss.

HP CONFIDENTIAL Codename: Mount Olympus Part Number: 281405-004 Last Saved On: 7/31/03 1:39 PM
Removal and Replacement Procedures
To remove a hot-plug hard drive:
1. Open the front bezel door (tower model only). Refer to the “Removing the Front Bezel
Door (Tower Model Only)” section in this chapter.
CAUTION: Remove or replace a hard drive only when the drive failure LED is amber.
Data loss can occur if a hard drive is removed when the drive online LED is green. Refer
to the “Hot-Plug Hard Drive LEDs” section in Chapter 4 for more information.
CAUTION: Remove or replace only one hard drive at a time. The controller relies on
other hard drives to reconstruct data on the replaced hard drive. Hard drive reconstruction
is active when the drive online LED is flashing green.
2. Push the sliding release button (1).
