HP 640 RPS/EPS Safety and Regulatory Information
To avoid personal injury or product damage when installing your 640 RPS/EPS, read the installation precautions and guidelines
below.
Installation Precautions
Warnings
Do not mount the 640 RPS/EPS on a wall.
■
Do not carry the 640 RPS/EPS by using the handles of any installed power supplies.
■
The rack or cabinet should be adequately secured to prevent it from becoming unstable, tilting or falling.
■
Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices at
■
the bottom and progressively lighter devices above.
Cautions
Ensure the power source circuits are properly grounded, then use the power cord supplied with the X331 or X332
■
power supplies that you install into the 640 RPS/EPS to connect to the AC power source.
If your installation requires a different power cord than the one supplied with the X331 or X332 power supplies, be
■
sure the cord is adequately sized for the power supply's current requirements. In addition, be sure to use a power
cord displaying the mark of the safety agency that defines the regulations for power cords in your country/region.
The mark is your assurance that the power cord can be used safely with the power supplies.
When installing the 640 RPS/EPS, the AC outlet should be near the 640 RPS/EPS and should be easily accessible in
■
case the 640 RPS/EPS must be powered off.
Ensure the 640 RPS/EPS does not overload the power circuits, wiring, and over-current protection. To determine
■
the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same
circuit as the 640 RPS/EPS and compare the total with the rating limit for the circuit. The maximum ampere ratings
are usually printed on the devices near the AC power connectors.
Do not install the 640 RPS/EPS in an environment where the operating ambient temperature exceeds its specification.
■
Ensure the air flow around the 640 RPS/EPS is not restricted. Leave at least 7.6 cm (3 inches) for cooling. For the
■
air flow direction, see the Installation and Getting Started Guide for your product, located on the HP Networking
web site at www.hp.com/networking/support.
For additional Safety and Regulatory information, refer to the Safety and Regulatory documentation included with your
640 RPS/EPS, and to the safety and regulatory documentation on the HP web site at
EnterpriseProducts, and to the HP 640 RPS/EPS Installation and Getting Started Guide that can be found on the HP
Networking web site: www.hp.com/networking/support.
