Why has PowerChute Software lost communication with UPS after communication cable has been unattached and reattached?
After detaching the communication cable and then reattaching the communication cable, PowerChute Software does not reestablish communications with the UPS.
PowerChute Serial Shutdown
PowerChute Business Edition
All supported OS communicating with UPS via USB or Serial to Smart-UPS
NOTE: PowerChute Business Edition versions up to 10.0.5 are incompatible with Back-UPS.
The communications cable was unattached while the PowerChute service or daemon was running on the OS.
1 – Stop the PowerChute service or daemon before detaching and reattaching the communications cable.
2 – If the cable is unattached while the server or daemon is running, you can re-establish communications by
a: Stopping and restarting the server or daemon.
b: If step a does not resolve the issue, stop the service or daemon again, reattach the cable, and then brain-dead the UPS. See Video: How to perform a cold start and brain dead on Smart-UPS for instructions on how to brain-dead a Smart-UPS.
