Hi, I have a 48port 3750 PoE switch running ip base 122-46.SE. The switch is connected to RPS2300.
The issue is when I test the RPS failover, the switch fails over to the RPS ok, however when it fails back by manually pushing the standby and active button, the switch shows the following error on all ports regardless of if there is anything plugged into that port, or if it is non-PoE, and the PoE LED on the front flashes amber.
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Fa1/0/46: Power Controller reports power supply VEE under voltage and lockout
As a result the PoE devices (phones in this case) are off. The way I clear the issue is either to reboot the switch or issue the following on all ports.
switch(config)#int range f1/0/1-48
switch(config-if-range)#power inline never
switch(config-if-range)#power inline auto
Any ideas as to why it does this, as it sort of negates the point of RPS if all my Phones go off when power is restored to the switch and taken off the RPS.
As pointed by Kevin this is a normal behavior. Even I was surprised when I encountered this for the first time.
We need to understand that RPS is not UPS. It's supposed to support the devices in case the internal power supply fails and not in case of the power failure itself. It's a well know issue.
Have a look at limitations of RPS -
Its actually a BUG :) CSCdx81023 without a workaround.
