Hi there,
I have connected my Avaya IPO and 50 port switch to a APC uninterrupted power supply (UPS) unit to keep the phone system alive during a power cut.
When I kill power to the UPS unit to simulate a powercut the 50 port PoE ERS-4550T-PWR switch looses power for what must be a split second; so all my IP phones reboot.
Is a different type of UPS (online) the only answer ?
Any advice would be much appreciated.
