SRX 550 Power question

    Hi,

    We have an SRX 550 with dual power supplies.
    We are upgrading power in our DC from 120v 20amp power to 208v 20 amp power (PDU also getting swapped to support new power).

    Will the SRX tolerate mixed voltages (1 PDU will be attached to the 120v and the other to the 208v) for a short period so we do not have to reboot the device?

    Anyone have experience with this?

     

    Thank you!

    Hi,

     

    Inout voltage is between 100 to 240 VAC & PEM on SRX550 is hot swappable, hence I dont see you to have an issue with mixed voltage.

     

    Reference :- https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/specifications/ac-power-supply-srx550-electrical-specification.html

     

    To be on the safer side choose a time safe enough to perform the switch and monitor the alarms on the box during the change.
