Connecting Power To The Msa - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive Maintenance And Service Manual

Connecting power to the MSA

HP strongly recommends using the power cord shipped with the MSA. If using a different power cord,
your power cord should be approved for use in your country. The power cord must be rated for the
product and for the voltage and current marked on the electrical ratings label of the product. The voltage
and current rating of the cord should be greater than the voltage and current rating marked on the
product. In addition, the diameter of the wire must be a minimum of 1.02 mm² or 18 AWG. If you are
using 18 AWG, your maximum length may be up to 3.65 meters (12 feet).
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon it
or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the
cord exits from the product.
After all hardware components are installed and the unit is in place, the power can be connected.
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord's 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.
1.
Plug one end of the AC power cord into a power supply on the rear of the MSA. The power supply
automatically senses the input voltage. It is not necessary to select the correct main voltage.
2. Plug the other end of the AC power cord into a nearby, grounded outlet.
3. Plug the second AC power cord into the redundant power supply.
4.
Plug the second AC power cord into a grounded outlet nearby.
