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 Uninterrupt-ible 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 out-let.

• 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 add-ing 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 con-trolled.

• 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 ETER-NUS 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.

1. Overview Power Management for Power Synchronization

Power Management for Power Synchronization

This section explains power management with a power synchronized unit.

The power synchronized unit detects the AC power output of the target devices for power synchronization andcommands the ETERNUS DX/AF to synchronize the power with the target devices.When the power synchronized unit detects the AC power output of any server UPS unit, the power synchronizedunit commands the ETERNUS DX/AF to turn on.When the power synchronized unit does not detect AC power output in any of the server UPS units, the power syn-chronized unit commands the ETERNUS DX/AF to turn off.The server UPS unit must have a function in the management software that controls the AC power output accord-ing to when the server powers on and off. The server UPS unit must have one unused outlet to connect to thepower synchronized unit.

Connect the power cords of the ETERNUS DX/AF and the power synchronized unit to a UPS (UPS for the ETERNUSDX/AF) that uses a power line that is not the same as the server UPS unit. This enables power to be supplied orstopped according to the scheduled operations and the power failure settings of the server.
