Planning for power requirements

You must select a storage system location that meets specific power requirements.
When you consider the storage system location, consider the following issues:
v Power control selections
v Power outlet requirements
v Input voltage requirements
v Power connector requirements
v Remote force power off switch requirements
v Power consumption and environment
IBM cannot install the storage system if your site does not meet these power
requirements.
Attention: Implementation of surge protection for electronic devices as described
in the EN 62305 standard or IEEE Emerald Book is recommended. If a lightning
surge or other facility transient voltages occur, a surge-protection device limits the
surge voltage that is applied at the storage system power input. A surge-protection
device is required for facilities in Korea or customers that conform to the European
EMC Directive or CISPR 24.
Overview of storage system power controls
The storage system contains power controls on the frames. The power controls can
be configured by a technical service representative. The power controls can also be
accessed through the management console.
The storage system has the following manual power controls in the form of
physical switches that are on the racks:
