Understanding the SRX320 Services Gateway Power Supply
The power supply for the SRX320 Services Gateway is external. You must use the
following power supply adapters provided by Juniper Networks to provide power to the
services gateway.
•
75 W, 12 V power supply adapter for non-PoE models
•
280 W, 54 V power supply adapter for PoE models
Each PoE port delivers a maximum power of 30 W. Because of line loss, the powered
device connected to a PoE port can use only 25.5 W of power. Line loss is influenced
by cable length, quality, and other factors and is typically less than 16 percent of the
maximum power.
