SRX345 Power System
SRX345 Firewall Power Supply
The SRX345 Firewall is available with either a single AC power supply (Junos OS Release 15.1X49-D35 and later), dual AC power supplies (Junos OS Release 15.1X49-D110 and later), or a single DC power supply (Junos OS Release 17.4R1 and later). The power supply distributes the different output voltages to the device components according to their voltage requirements. The power supply is fixed in the chassis and is not a field-replaceable unit.
To identify the SRX345 model, check the Description field in the output of
the show chassis hardware command.
The following are sample outputs for the different SRX345 models.

If one power supply on an SRX345 (with dual AC power supplies) fails, the remaining power supply redistributes the electrical load without interruption.
