Removal and Replacement Procedures

Rack Warnings and Cautions

WARNING: Because the rack allows stacking of computer components on a vertical rather than horizontal plane, be sure that precautions have been taken to provide for rack stability and safety. It is important to follow these precautions providing for rack stability and safety, and to protect both personnel and property. Heed all cautions and warnings throughout the installation instructions provided with the device.

WARNING: To reduce the risk of personal injury or damage to the equipment:

• Observe local occupational safety requirements and guidelines for heavy

equipment handling.

• Obtain adequate assistance to lift and stabilize the product during installation or

removal.

• Always load the heaviest item first, and load the rack from the bottom up. This

makes the rack bottom-heavy and helps prevent the rack from becoming unstable.

• Extend the leveling jacks to the floor.

• Rest the full weight of the rack on the leveling jacks.

• Attach the stabilizing feet to the rack if it is a single-rack installation.

• The racks are coupled together in multiple-rack installations.

• Fully extend the bottom stabilizers on the equipment. Be sure that the equipment is

properly supported/braced when installing options and boards.

• Be sure that the rack is adequately stabilized 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 for any reason.

• Do not attempt to move a fully loaded equipment rack. Remove equipment from the

rack before moving the rack.

• At least two people are needed to safely unload the rack from the pallet. An empty

42U rack weighs 115 kg (253 lb), is over 2.1m (7 ft) tall, and may become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet; handle it from the sides. Stabilize the device by keeping the unit on the rails.

Device Warnings and Cautions

Before installing a system, be sure that you understand the following warnings and cautions.

WARNING: To reduce the risk of personal injury or damage to the equipment, observe all warnings and cautions throughout this chapter.

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.

HP CONFIDENTIAL Codename: Aurora Part Number: 251850-004 Last Saved On: 9/19/03 10:57 AM

Removal and Replacement Procedures

WARNING: Be sure that the AC power supply branch circuit that provides power to the rack is not overloaded. Not overloading AC power to the rack power supply circuit 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 wiring and installation requirements.

WARNING: To reduce the risk of personal injury or damage to the equipment, the installation of options other than hot-plug power devices should be performed only by individuals who are qualified in servicing computer equipment and trained to deal with products capable of producing hazardous energy levels.

WARNING: To reduce the risk of electric shock or damage to the equipment:

• Do not disable the 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 the power supply to disconnect power to the

equipment.

• Do not route the power cord where it can be walked on or pinched by items placed

against it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends from the system.

• Do not use conductive tools that could bridge live parts.

Weight Warning

• Remove all watches, rings, or loose jewelry when working in hot-plug areas of an

energized device.

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

CAUTION: Protect the device 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.

WARNING: The MSA500 system weighs 22.7 kg (50 lb) when assembled for shipping. To reduce the risk of personal injury or damage to equipment:

22.7 kg

50 lb

• Observe local health and safety requirements and guidelines for manual

material handling.

• Obtain adequate assistance to lift and stabilize the MSA500 system during

installation or removal.

• Remove all tape drives, if installed, to reduce the overall weight of the

system.

Removal and Replacement Procedures

System Power Down

WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power cord to remove power from the system. The front panel Power On/Standby button does not completely shut off system power. Portions of the power supply and some internal circuitry remain active until AC power is removed.

IMPORTANT: If installing a hot-plug device, it is not necessary to power down the system.

To power down the system:

1. Power down any attached servers. Refer to the server documentation.

2. Press the Power On/Standby button. Wait for the system power LED to go from green to off.

3. Disconnect the power cords.

Hard Drive Blank

CAUTION: Always populate drive bays with either a hard drive or blank. Proper airflow can

only be maintained when the bays are populated. Operating the system with unpopulated drive bays can lead to improper cooling and thermal damage.

To remove the component:

To replace a blank, slide the blank into the bay until it locks into place.

HP CONFIDENTIAL Codename: Aurora Part Number: 251850-004 Last Saved On: 9/19/03 10:57 AM

Hot-Plug SCSI Hard Drive

CAUTION: If you must replace a hot-plug drive, follow the guidelines in this section. Failure

to do so can result in data loss and can void the warranty.

RAID 0 is not a fault-tolerant configuration. Never remove a drive from a RAID 0 array unless it has failed. Drive failure is indicated by an amber drive failure LED. In a RAID 0 configuration, removal of an operating drive results in data loss. To remove a drive without losing data, always back up the entire array, replace the drive, and restore the entire array. Backing up a single drive and replacing it does not restore the array.

Some instances exist in which you may replace a drive in RAID 1, 5, and Advanced Data Guarding configurations. To determine when drive replacement is possible without data loss, use the hot-plug SCSI hard drive LEDs combination table in Chapter 4, “Component Identification.”

Follow these additional guidelines when replacing drives:

• Never remove more than one drive at a time (or two drives if you are using

Advanced Data Guarding). When you replace a drive, the controller uses data from the

other drives in the array to reconstruct data on the replacement drive. If you remove more than one drive, a complete data set is not available to reconstruct data on the replacement drive(s) and permanent data loss could occur.

Removal and Replacement Procedures

• Never remove a drive while the controller is rebuilding another drive. A drive’s

online LED flashes green while it is being rebuilt. The controller requires the data from all other drives to rebuild the replacement drive.

• If the system has an online spare drive, wait for it to complete rebuilding before

replacing the failed drive. When a drive fails, the online spare becomes active and

begins rebuilding as a replacement drive. After the online spare has completed Automatic Data Recovery (the online LED is continuously lit), replace the failed drive with a new replacement drive. Do not replace the failed drive with the online spare. The system automatically rebuilds the replacement drive and resets the spare drive to an available state.

• If you replace a drive while the system is off, it may be necessary to rebuild the

replaced drive.

Removal and Replacement Procedures

To remove the component:

1. Be sure that the online and activity LEDs on the failed drive are both off.

CAUTION: To prevent improper cooling and thermal damage, do not operate the system unless all bays are populated with either a component or a blank.

2. Remove the failed drive.

To replace a hot-plug SCSI hard drive:

1. Slide the drive into the bay until it locks into place.

2. Close the lever.

CAUTION: Data loss can occur if the drive is not firmly seated.

3. Be sure that the drive LEDs illuminate one at a time and then turn off together to indicate that the system has recognized the new drive.

In fault-tolerant configurations, allow the replacement drive to be reconstructed automatically with data from the other drives. While reconstruction is in progress, the online LED flashes.
