Hi,

Based on your other posts I assume you are running PowerChute Network Shutdown on the servers. Based on that assumption you can configure sequenced server shutdown from within PowerChute. See page 81 of the PowerChute User's Guide. The shutdown is configured from within the PowerChute web interface by selecting  Configure Events - Runtime remaining below threshold and clicking on shutdown. When the battery drops below the set amount of time PowerChute will begin the shutdown process for the server. Each server should be running PowerChute and each can be configured with a different amount of remaining runtime.

You can also configure sequenced shutdown also known as load shedding from within the network card depending on the model of UPS and network card installed. We would need to know the model of the UPS and network card and network card firmware to provide details.

I have another question? Should I open another post?

How could I setup Sequenced Server Shutdown with different runtime remaining threshold like in the Standard User Guide? Where I find the configuration for different threshold at the agents?

Hi,

You can configure load shedding for that unit. 

Load Shedding

Use these settings to automatically shut down an outlet in response to one or more conditions. To enable a condition, mark its checkbox and configure its value; you can enable multiple conditions.

  • Conditions to turn off this outlet group:
    • power failure is longer than ___ seconds: An input power failure continued for more than this number of seconds.
    • UPS runtime remaining is less than ___ seconds: The number of seconds the UPS can support the current load while operating on battery power has dropped below this number of seconds.
    • UPS is overloaded: The output drawn from the UPS exceeds the rated limit.
  • Settings that determine how the outlet group is turned off:
    • Skip outlet off delay: Shut down the outlet group immediately.
    • Stay off after power returns: The outlet remains off until you turn it on.

If you use PowerChute Network Shutdown (PCNS) on this outlet, be sure "Skip outlet off delay" is not checked so that PCNS clients can safely shutdown. Also, each PCNS client has its own set of conditions that may be configured to start a shutdown.

When configuring load shedding remember anything that is connected to the specified outlet group will loose power when the outlet group powers down. If not protected by PCNS and if PCNS has not been associated with the outlet group that is shutting down any attached systems will have AC cut and go down hard.
