ISR4321 power supply

Hi everyone

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.

Hi Rolando
Thank you for your answer.
I don't understand why is written 2 voltages on the connector if it doesn't
work just only with the 12V...
Thanks

I think the connector will work with both power levels since the router has 2 power supply options:  PWR-4320-AC and the PWR-4320-POE-AC.  You will probably need to open a TAC case to find the specs.  In a DC environment, it would be nice to use a direct DC connection if we knew the pinouts and power levels.
