SRX4700 Power System
The SRX4700 power system includes AC and DC power supply units (PSUs) and related power cords, cables, and cable lugs. The PSUs operate within specified ranges and are equipped with alarms and indicators.
The SRX4700 Firewall ships with two AC or two DC PSUs (1+1 redundancy) preinstalled in the rear panel of the chassis in slots labeled 0 and 1. These PSUs are hot-removable and hot-insertable field replaceable units (FRUs). You can install the PSUs without powering off the firewall or disrupting the firewall function.
The SRX4700 firewall supports the following AC and DC PSUs:
JNP-PWR2200-AC
JNP-PWR2200-DC
Do not mix AC and DC PSUs in the same chassis.
SRX4700 AC Power Supply Unit
The SRX4700 firewall supports 2200-W AC PSUs that you can monitor using an inter-integrated circuit (I2C) bus from the boot complex programmable logic device (boot CPLD). The PSUs directly plug into the connectors provided on the CPU board. The 12 V outputs from both the PSUs are shorted on the main board and are used by on-board voltage regulators for generating downstream voltages.
Each AC PSU weighs approximately 2.42 lb (1.1 kg) and consists of a handle, an ejector lever, an AC appliance inlet, a fan, and a bicolor LED that helps monitor the status of the PSU. Each inlet requires a dedicated AC power feed and a dedicated customer-site circuit breaker. We recommend that you use a minimum 16 A customer-site circuit breaker, or as required by local code.

Each AC PSU provides power to all components in the firewall. The two PSUs provide full power redundancy to the firewall. If one PSU fails or is removed, the second PSU balances the electrical load without interruption. The firewall reassesses the power required to support the firewall configuration and issues error messages if the available power is insufficient.
The firewall is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground.

Supported AC Power Cords
A detachable AC power cord is supplied with the AC PSUs. The coupler is type C19 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.
Table 3 lists the default power cord that is provided for each country.
The AC power cord provided with each PSU is intended for use with that PSU only and not for any other use.
In North America, AC power cords must not exceed 4.5 m 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 switch are in compliance.

SRX4700 DC Power Supply Unit
The DC PSU is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install it without powering off the firewall or disrupting the firewall function.
Each DC PSU weighs approximately 2.42 lb (1.1 kg) and consists of a handle, an ejector lever, a bi-color status LED, and a terminal block that provides a single DC input (–48/–60 VDC and return). The DC PSU requires a dedicated customer-site circuit breaker. We recommend that you use a dedicated customer-site circuit breaker rated for 60 A (80 VDC), or as required by local code.

DC Power Circuit Breaker Requirements for the SRX4700 Firewall
Each DC PSU has a single DC input (–48 VDC and return) that requires a dedicated circuit breaker. We recommend that you use a dedicated customer-site circuit breaker rated for 60 A (80 VDC), or as required by local code. Doing so enables you to operate the firewall in any configuration without upgrading the power infrastructure.
DC Power Cable Specifications
DC Power Cable Lug Specifications
The DC power lug LCD-14A-L accommodates 6 AWG (13 mm²) stranded wire. The grounding cable that you provide for the chassis must be the same size as or heavier than the input wire of each PSU. Minimum recommendations are 6 AWG (13 mm²) stranded wire, minimum 60 °C wire, or as permitted by local code.
DC power cords and lugs are not supplied with the DC PSUs.
Install heat-shrink tubing insulation around the power cables at the connection point of the DC power supply terminal.
Before you install the firewall, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the firewall.
DC Power Cable Specifications
You must supply four DC power cables that meet the following specifications: 6 AWG (13 mm²) stranded wire, minimum 60 °C wire, or as permitted by local code.
Install heat-shrink tubing insulation around the power cables at the connection point of the DC PSU terminal.
