Planning the Installation WARNING: The ProLiant BL e-Class server blade enclosure is 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 server blades and power supplies from the enclosure before installing or removing the enclosures. • Use caution and get help to lift and stabilize an enclosure during installation or removal, especially when the enclosure is not fastened to 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: The ProLiant BL e-Class server blade enclosure has two power cords for redundant AC power sources. If it is necessary to remove power for servicing, disconnect all power by removing both power supply cords from either the wall or the AC connectors on the rear of the enclosure. CAUTION: When servicing non-hot-plug components, you must power down the server blades and/or the enclosure and server blades. However, it may be necessary to leave the server blades powered up when performing other operations, such as hot-plug replacement or troubleshooting. CAUTION: Protect the equipment from power fluctuations and temporary interruptions with a regulating UPS device. 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: Always be sure that equipment is properly grounded before beginning any installation procedure. Electrostatic discharge resulting from improper grounding can damage electronic components. For more information, see Appendix B, "Electrostatic Discharge." CAUTION: Do not remove a power supply without having a replacement ready to install. A failed power supply must remain in the system for proper airflow to prevent overheating while the system is operating. HP ProLiant BL e-Class System Setup and Installation Guide 2-5

Planning the Installation
WARNING:
The ProLiant BL e-Class server blade enclosure is 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 server blades and power supplies from the enclosure before
installing or removing the enclosures.
•
Use caution and get help to lift and stabilize an enclosure during
installation or removal, especially when the enclosure is not fastened to 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:
The ProLiant BL e-Class server blade enclosure has two power
cords for redundant AC power sources. If it is necessary to remove power for

operation during a power failure.
CAUTION:
Always be sure that equipment is properly grounded before beginning
