Chapter 1 Overview 1.6 Power Management for Power Synchronization

1.6 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 and commands the ETERNUS DX S2 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 synchronized unit commands the ETERNUS DX S2 to turn on.When the power synchronized unit does not detect AC power output in any of the server UPS units, the power synchronized unit commands the ETERNUS DX S2 to turn off.The server UPS unit must have a function in the management software that controls the AC power output according to when the server powers on and off. The server UPS unit must have one unused outlet to connect to the power synchronized unit.

Connect the power cords of the ETERNUS DX S2 and the power synchronized unit to a UPS (UPS for the ETERNUS DX S2) that uses a power line that is not the same as the server UPS unit. This enables power to be supplied or stopped according to the scheduled operations and the power failure settings of the server.
