HP BladeSystem c3000 Tower Enclosure Setup and Installation Guide

Planning the installation 8
WARNING: A risk of electric shock from high leakage current exists. Before connecting the AC
supply to the power enclosures, be sure that the electrical outlets are properly grounded
(earthed).
The area where the enclosure is installed should be designated as a restricted access area,
and the enclosure is intended to be used with a dedicated uninterruptible power supply (UPS)
that uses an industrial style wall plug to insure a reliable protective earth ground connection.
Each power supply in the enclosure can also be plugged directly into a low-line wall outlet. Be
sure there is enough total amperage available in the wall outlets of your facility to handle all
power supplies installed in the enclosure. To determine the total amperage draw of your HP
BladeSystem c3000 Tower Enclosure configuration, see the HP power calculator
(http://www.hp.com/go/bladesystem/powercalculator
).
Only trained service personnel must perform installation and maintenance.
CAUTION: Always be sure that equipment is properly grounded and that you follow proper
grounding procedures before beginning any installation procedure. Improper grounding can
result in ESD damage to electronic components. For more information, refer to, "Electrostatic
discharge (on page 79)."
CAUTION: When performing non-hot-plug operations, you must power down the server blade
and/or the system. Use caution when performing other operations, such as hot-plug
installations or troubleshooting.
CAUTION: Protect the equipment from AC power fluctuations and temporary interruptions with
a regulating facility 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.
IMPORTANT: Data on the dimensions and weights of HP BladeSystem c-Class components can
be found in the HP BladeSystem c-Class Maintenance and Service Guide. The same data can
be determined by using the online HP BladeSystem c-Class Sizing Utility.
Space and airflow requirements
To enable servicing and ensure adequate airflow, observe the following spatial requirements when
deciding where to install the HP BladeSystem c3000 Tower Enclosure:
• Leave a minimum clearance of 63.5 cm (25 in) in front of the enclosure.
• Leave a minimum clearance of 76.2 cm (30 in) in back of the enclosure.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the enclosure to the rear of
another enclosure, rack, or row of racks.
HP BladeSystem servers draw cool air in through the front and expel warm air through the rear of the
enclosure. Therefore, the front of the enclosure must be adequately ventilated to enable ambient room air
to enter the enclosure, and the rear of the enclosure must be adequately ventilated to enable the warm air
to escape from the enclosure.
IMPORTANT: Do not block the ventilation openings.
