PowerChute Business Edition – Simple Signaling with Interface Expander 2 card shutdown delay
There is a delay in shutting down clients in a Simple Signalling configuration with an Interface Expander 2 card.
PowerChute Business Edition v9.5 and above
Simple Signaling with Interface Expander 2 card (AP9624)
After the UPS and Interface Expander 2 card issue a shutdown command for the Master server and simple clients, a turn off command is also issued to turn off the UPS. In order to ensure graceful shutdown of all clients, the delay of this turn off command is forced to be equal to the values set for “Time for operating system to shut down” and “At runtime limit” in the Shutdown Settings screen of the Master server.
However, for Type B UPS devices, an additional delay is added to the “At runtime limit” value for any time setting greater or equal to 10 minutes. See the table below for the different time delays:
|User-Specified Delay (At runtime limit)
||Interface Expander 2 Time Delay
||No additional delay (2 minutes in total)
||No additional delay (5 minutes in total)
||No additional delay (7 minutes in total)
||6 minutes (16 minutes in total)
||6 minutes (18 minutes in total)
||6 minutes (21 minutes in total)
||6 minutes (24 minutes in total)
||12 minutes (32 minutes in total)
