SRX320 Power System
Understanding the SRX320 Firewall Power Supply
The power supply for the SRX320 Firewall is external. You must use the following power supply adapters provided by Juniper Networks to provide power to the services gateway.

280 W, 54 V power supply adapter for PoE models
Figure 2: 280 W, 54 V Power Supply Adapter
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.

Power Cord Specifications for SRX320
A detachable power cord is supplied with the device. The coupler is type C13 as described by International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.
In North America, AC power cords must not exceed 4.5 meters (approximately 14.75 feet) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the device are in compliance.
Table 2 lists the AC power cord specifications for the countries and regions listed in the table.
