1200R - Power Supply Question

#1200R #Power supply

We have two ways to connect the power source to the unit.

1) how to verify if the power source connected is actually from rear or front(DC terminal block). 

2) Whether firewall support both power connected, if yes would it auto failover if one fail?

Re: 1200R - Power Supply Question

1200R support two power feeds.

• AC: 100-240V, 50 – 60 Hz (power adapter operating temp: 0 to 40°C)

• DC: 12V-72V, -48V DC

It does support auto failover, once one power feed is failing, power is switched to the second input.

(ORing diode between the 2 sources)

If both are connected and Active, DC takes precedence.

Thanks Amir. Is there a command that i could use to verify which one is used currently?

The command that gives the most information is show diag, I don't have a 1200R to test it, but that is where I would look for it.

Could be that show diag does not show that - i have no DC power connected, just AC PSU, and i only see:

Yes thats right, with DC connected I couldnt notice any difference.
