Understanding the SRX345 Services Gateway Power Supply
The SRX345 Services Gateway uses a fixed, internal AC power supply. 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 field-replaceable.
The power supply has a single AC appliance inlet that requires a dedicated AC power
feed.
NOTE: The services gateway is availablewith either a single AC power supply
or dual AC power supplies.
