Shutdown on Configuration menu
Path: Configuration > Shutdown
Use this screen to configure the parameters of a UPS shutdown. See the table below and also “Controlled
Early Shutdown and End of Shutdown”.
Start of Shutdown
Define the delays and durations that are considered when a UPS shutdown is required.
Basic Signaling Shutdown.
Basic Signaling or “Simple Signaling” is a simple method of communication between a UPS and a server,
workstation or third party system. The Interface Expander 2 (AP9624) is a Smart Slot accessory that can
provide simple signaling for your UPS. UPS Simple Signaling can provide notification and graceful system
shutdown, but does not provide the continuous advanced monitoring features available with advanced or smart
signaling.
NOTE: If you are using PowerChute Network Shutdown, it is not recommended to use Basic
Signaling Shutdown. For certain UPS models, options such as Basic Shutdown Delay can impact
UPS shutdown and supersede the Low Battery Duration, which is used by PowerChute to calculate
the total shutdown time required.
Field Description
Low Battery
Duration
For a UPS on battery, this defines a runtime remaining threshold, below which a low
battery condition is triggered on the UPS. For example, if the Low Battery Duration is
set to ten minutes and the UPS predicted runtime remaining reaches ten minutes or
below, a low battery condition is triggered. If input power is not restored to the UPS, it
will turn off when the battery has exhausted.
A low battery condition will trigger a shutdown on all PowerChute Network Shutdown
clients associated with the NMC.
Maximum
Required Delay
Calculates the delay needed to ensure that each PowerChute client has enough time
to shut down gracefully when the UPS or the PowerChute client initiates a graceful
shutdown.
• It is the longest shutdown delay needed by any server listed as a PowerChute
Network Shutdown client.
• It is calculated whenever the management interface of the UPS turns on or is reset,
or when the Force Negotiation option is selected and you click Apply.
See “Shutdown delays and PowerChute Network Shutdown”.
Field Description
Basic Signaling
Shutdown
Enable Basic Signaling Shutdown if you have connected a server, workstation or third
party system to your UPS using a basic signaling cable. Enable it if your UPS does
not support advanced signaling, or is configured to communicate in basic signaling.
