I am beginner on this forum ...
I see that ISR4321 has 2 power supply possibilities as written on the connector.
My question is that can I power it from the existing rack with 48V instead with the delivered 12V power supply?
If yes somebody has the pin asignement for this?
This can much easier my job because it will installed on Telekom technical room where we have already available 48V dc.
Thank you all
No, you need the adapter or you will burn it since the voltage is different.
The adapter if it supports 48v, then it can go the your PDU.
PDU --> Power adapter --> Router.
