American Power Conversion AP9207 manual Behavior Confirmed shutdown mode

Configuring Share-UPScontinued

Confirmed In Confirmed mode, Share-UPS shuts down the UPS after shutdown mode all connected servers have signaled that they have com-

pleted shutdown of the operating system.

Note: Do not use Confirmed mode if any server connected to Share-UPS Basic ports is incapable of sending a shutdown confirmation signal. See “PowerChute plus support for Confirmed shutdown mode,” on page 25.

Behavior of

Confirmed shutdown mode

Unoccupied ports and ports connected to unpowered servers are considered to have confirmed shutdown.

If utility power returns before any connected server has sig- naled shutdown of the operating system, Share-UPS returns to On Line status.

If Share-UPS detects a Low Battery condition in the UPS before all connected servers have signaled shutdown of the operating system, it notifies the servers that the UPS battery is exhausted, shutting down the UPS after the Low Battery Signal Time has elapsed.

If utility power returns after at least one server has con- firmed shutdown of the operating system, but before all servers have confirmed system shutdown, Share-UPS forces On Battery and Low Battery signals so that the remaining servers shut down as well. Share-UPS sends the forced Low Battery signal for a period of time equal to the Low Battery Signal Time and then shuts down the UPS, which cycles power to restart the servers.

If none of the Share-UPS ports are connected to a powered server, Share-UPS operates in Until Low Battery shutdown mode, as described in “Until Low Battery shutdown mode,” on page 26.
