HP Networking Safety and Compliance manual Precautions for power products, Power cords

•Some products have covers or doors to access hot-plug components and may allow access to hazardous energy circuits or moving fans.

◦The doors should remain locked during normal operation.

OR

◦The server should be installed in a controlled access location where only qualified personnel have access to the server.

•Power down the equipment and disconnect all AC power cords before removing any access covers for non-hot-plug areas.

•Do not replace non-hot-plug components while power is applied to the product. First, shut down the product and disconnect all AC power cords.

•Do not exceed the level of repair specified in the procedures in the product documentation. All troubleshooting and repair procedures are detailed to allow only subassembly or module-level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.

•For floor-standing products, install and extend bottom stabilizers before installing options and boards.

•Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. This will reduce the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.

Precautions for power products

Power cords

To reduce the risk of electric shock or damage to the equipment:

•Use an approved power cord. If you have questions about the type of power cord to use, contact your HP authorized service provider.

•If you have not been provided with a power cord for your computer or for any AC-powered option intended for your product, purchase a power cord that is approved for use in your country.

•You must use a power cord rated for your product and for the voltage and current marked on the electrical ratings label of the product. The voltage and current rating of the cord must be greater than the voltage and current rating marked on the product.

•Do not place objects on AC power cords or cables. Arrange them so that no one may accidentally step on or trip over them.

•Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord by the plug.

•Make sure that the total ampere rating of all products plugged into an extension cord or power strip does not exceed 80 percent of the ampere ratings limit for the extension cord or power strip.

•Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

•Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
