Notes:
For more information on PowerChute shutdown sequences, see “Sample Shutdown Scenarios” in
the PowerChute Network Shutdown User Guide on the APC website.
During the comparison of the PowerChute Required Shutdown time and the NMC Maximum
Required Delay/Outlet Group Power Off Delay, the largest value is used. For example, if the
PowerChute client command line shutdown duration is set to 8 minutes, but the UPS Low Battery
Duration is 10 minutes, the NMC will use the larger value of 10 minutes for the Maximum Required
Delay.
In Forced Negotiation, the NMC polls the PowerChute Clients to get their required shutdown time.
As a result it can take up to ten minutes for the Maximum Required Delay/Outlet Group Power Off
delay values to update.
PowerChute never changes the NMC Low Battery Duration field value.
With PowerChute Network Shutdown v3.x or higher, the Maximum Required Delay value is never
used by the NMC for a UPS with outlet groups.
