COMPAQ CONFIDENTIAL Codename: AvalancheX Part Number: 316080-001 Last Saved On: 12/18/02 11:31 AM

Removal and Replacement Procedures

WARNING: Setting the server blade Power On/Standby button to the standby position removes power from most areas of the server blade. This process may take 30 seconds, during which time some internal circuitry remains active. To remove power completely, remove the server blade from the server blade enclosure.

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

CAUTION: When performing non-hot-plug operations, you must power down the server

blade and/or the system. However, it may be necessary to leave the server blade powered up when performing other operations, such as hot-plug installations or troubleshooting.

Rack Warnings and Cautions

WARNING: The power supply enclosure and the server blade enclosure are very heavy. 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.

• Remove hot-plug power supplies and server blades from their enclosures before

installing or removing the enclosures.

• Use caution and get help to lift and stabilize enclosures during installation or

removal, especially when the enclosure is not fastened to the rack.

WARNING: Always use at least two people to lift a power supply enclosure or server blade enclosure into the rack. If the enclosure is being loaded into the rack above chest level, a third person MUST assist with aligning the enclosure with the rails while the other two people support the weight of the enclosure.

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

• The leveling jacks of the rack are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizers are attached to the rack if it is a single rack installation.

• The racks are coupled in multiple rack installations.

WARNING: When installing the server blade enclosure in a telco rack, be sure that the rack frame is adequately secured to the building structure.

WARNING: To reduce the risk of personal injury or damage to the equipment, 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 2.1 m (7 ft) tall, and may become unstable when being moved on its casters. Do not only stand in front of the rack as it rolls down the ramp from the pallet, but handle the rack from both sides.

Removal and Replacement Procedures

Server Blade Components

Use the procedures in this section to perform service events on ProLiant BL20p server blades.

Server Blade Preparation

To service any internal server blade component, you must power down the server blade and remove it from the server blade enclosure.

CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning any installation procedure. For more information, refer to the “Electrostatic Discharge Information” section in this chapter.

System power in server blades does not completely shut off with the front panel Power On/Standby switch or Integrated Lights-Out (iLO) Virtual Power Button feature. The function toggles between on and standby modes, rather than on and off. The standby position removes power from most electronics and the drives, but portions of the power supply and some internal circuitry remain active.

To service internal server blade components:

1. Identify the proper server blade in the server blade enclosure.

2. Remove power from the server blade in one of the following ways:

— Use the Virtual Power Button feature in the iLO Remote Console to power down the

server blade from a remote location. Be sure that the server blade is in standby mode by observing that the power LED is amber.

— Press the Power On/Standby button on the front of the server blade. Be sure that the

server blade is in standby mode by observing that the power LED is amber.
