You can warm reboot the network management card interface (which does not affect the UPS output power). Go to Control->Network->reset/reboot and select restart management interface and then apply and carry out that action and the alarm should clear. There is an option in there to Reset Only: "Lost Environmental Communication Alarms" but I think there was a bug with it not working in certain firmware versions. You can try that first if you want if not, restart the management interface to clear it for sure.
