1.2 Features
This section explains the features of the power synchronized unit and the AC sensor unit.
• Powering the ETERNUS DX/AF on and off can be synchronized with a server by connecting to the
Uninterruptible Power Supply (UPS) unit to which the server is connected.
As well as the UPS unit to which the server is connected (referred to as "server UPS unit" in the remainder of
this manual), the power synchronized unit can be connected to a unit that can control the output of an AC
outlet.
• The sizes of the power synchronized unit and the AC sensor unit are 1U. These units can be installed in a
19-inch rack for the server or the ETERNUS DX/AF.
• Two server UPS units can be connected to manage power synchronization in a standard configuration. By
adding an AC sensor unit, up to 16 server UPS units can be connected.
• By serially connecting each AC sensor unit, the distance between a server UPS unit and a power
synchronized unit can be extended by up to 100m.
• By cascading power synchronized units, the power of up to eight ETERNUS DX/AF storage systems can be
controlled.
• A redundant configuration is available by using two power synchronized units.
• Power synchronization starts when the power synchronized unit is connected to the server UPS unit and
the ETERNUS DX/AF by cables. Connection procedures can be performed while the server UPS unit and the
ETERNUS DX/AF are operating.
• The status of the power synchronized unit and the status of the AC power output from the server UPS unit
are displayed on the LED. If an error occurs, tracking the error and error recovery can be performed based
on the LED information.
