• Power control selections
• Power outlet requirements
• Input voltage requirements
• Power connector requirements
• Remote force power off switch requirements
• 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:
Local/remote switch
(Available on base frames) The local/remote switch setting determines your use of local or remote
power controls. When you set the switch to local, the local power on/local force power off switch
controls power for the storage system. You can access this switch by opening the rear cover of the
storage system. When the local/remote switch is set to remote, the power for the storage system is
controlled by remote power control settings that are entered in the DS8000 Storage Management GUI
or DS Service GUI.
Planning requirements: None.
Local power on/local force power off switch
(Available on base frames) The local power on/local force power off switch initiates a storage system
power-on sequence or a storage system force power off sequence. This switch is applicable only
when the local/remote switch is set to local. You can access this switch by opening the rear cover of
the storage system.
Planning requirements: None.
iPDU circuit breakers
Each iPDU provides six circuit breakers which are activated (the breaker pole pops out) when the load
current rating for a power outlet exceeds 20 A. The circuit breaker is reset by firmly pressing the
breaker pole until it locks into place.
The following power controls can be configured by a technical service representative. You can also use
the following power controls through the DS8000 Storage Management GUI (running on the management
console):
Local power control mode
(Visible in the DS8000 Storage Management GUI) You cannot change this setting in the DS8000
Storage Management GUI. This mode is enabled when the local/remote switch that is on the storage
system is in the local position. When this setting is used, the local power on/local force power-off
switch that is on the storage system controls the power.
Planning requirements: None.
Power outlet requirements
Plan for the required power outlets for the installation of your storage system.
The following power outlets are required:
