D3000 Disk Enclosure MSG (734754-001, March 2014)

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 product 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.
Power supplies
Hot-plug power supplies are not designed to be removed or installed with AC power connected
to the power supply. To reduce the risk of electric shock or damage to the equipment when handling
hot-plug power supplies:
• Install the power supply before connecting the power cord to the power supply.
• Unplug the power cord before removing the power supply from the product.
• If the system has multiple sources of power, you must unplug all AC power cords from the
power supplies to completely disconnect power from the system.
Verify that the external power source connected to your product matches the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult your HP authorized service provider or local power company.
Powering off disk enclosures
IMPORTANT: Always power off disk enclosures after controller enclosures and servers.
IMPORTANT: When installing a hot-pluggable component, such as a disk drive, it is not necessary
to power down the enclosure.
To power off a disk enclosure:
1. Power off any attached servers. For more information, see the server documentation.
2. Power off the controller enclosure (if included in the configuration.) For more information, see
the controller enclosure documentation.
3. Disconnect power cords.
The system is now without power.
