HP BladeSystem c3000 Tower Enclosure Setup and Installation Guide

Planning the installation 9
If the enclosure is not completely filled with components, the remaining gaps between the components can
cause changes in the airflow, which can adversely affect cooling within the enclosure. Fill these gaps with
blanks.
CAUTION: Always use blanks to fill empty spaces in enclosures. This arrangement ensures
proper airflow. Using an enclosure without the proper blanks results in improper cooling that
can lead to thermal damage.
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the enclosure in a well-
ventilated, climate-controlled environment.
The operating temperature inside the enclosure is higher than the room temperature and is dependent on
the configuration of equipment in the enclosure. Check the TMRA for each piece of equipment before
installation.
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
• Do not permit optional equipment to impede airflow around the enclosure or to increase the
internal enclosure temperature beyond the maximum allowable limits.
• Do not exceed the TMRA of the manufacturer.
Power requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of IT equipment by licensed electricians. This equipment is designed to operate in installations
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of
Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the
product rating label or the user documentation supplied with that option.
WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not
overload the AC supply branch circuit that provides power to the enclosure. Consult the
electrical authority having jurisdiction over wiring and installation requirements of your facility.
CAUTION: Protect the enclosure from power fluctuations and temporary interruptions with a
regulating UPS. This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the enclosure in operation during a power failure.
Grounding requirements
This equipment must be grounded properly for proper operation and safety. In the United States, you must
install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250,
as well as any local and regional building codes.
In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA
C22.1, Canadian Electrical Code.
In all other countries, you must install the equipment in accordance with any regional or national electrical
wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
