Optimum environment
Specific requirements for space, power, temperature, and airflow must be met to provide optimum
performance with minimum maintenance for your rack environment.
For additional information, refer to the Best Practices document on the HP website
Space requirements
When deciding where to place your rack:
•
At least 1219 mm (48 in) of clearance is needed all the way around the pallet and above the rack
to enable the removal of the packing material.
•
At least 1219 mm (48 in) of clearance is needed in front of the rack to enable the door to open
completely.
•
At least 762 mm (30 in) of clearance is needed in the rear of the rack to provide access to
components.
•
At least 380 mm (15 in) of clearance is needed around a power supply to facilitate servicing.
Power requirements
When planning for power distribution requirements for your rack configuration:
•
The power load must be balanced between available AC supply branch circuits.
•
The overall system AC current load must not exceed 80% of the branch circuit AC current rating.
•
If a UPS is used, the load should not exceed 80% of the marked electrical current rating for the UPS.
This equipment must be installed in accordance with local and regional electrical regulations governing
the installation of information technology equipment by licensed electricians. This equipment is designed
to operate in installations covered by the Nation Electric Code (ANSI/NFPA-70, 1993) and the code for
protection of Electronic Computer/Data Processing Equipment (NFPA-75, 1992).
For electrical power ratings on options, refer to the products rating label or user documentation supplied
with that option.
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the rack in a well
ventilated, climate-controlled environment.
The operating temperature inside the rack is always higher than the room temperature and is dependent
on the configuration of equipment in the rack. Check the TMRA for each piece of equipment before
installation.
