SRX4600 Power System

Understanding the SRX4600 Firewall Power Supply

The SRX4600 Firewall ships with two AC or two DC power supplies (1+1 redundancy) preinstalled in the rear panel of the chassis in slots labeled 0 and 1. The SRX4600 Firewall power supply is a field-replaceable unit (FRU) and you can install it without powering off the firewall or disrupting the firewall function.

AC Power Supply

The AC power supply is a FRU and you can install it without powering off the firewall or disrupting the firewall function.

Each AC power supply weighs approximately 3.4 lb (1.54 kg) and consists of a handle, an ejection lever, an AC appliance inlet, an internal fan, and an LED to monitor the status of the power supply. The AC power supply supports both low-voltage line (800 W) and high-voltage line (1600 W).

Each inlet requires a dedicated AC power feed and a dedicated customer-site circuit breaker. We recommend that you use a minimum 15 A (110 VAC) customer-site circuit breaker, or as required by local code. Figure 1 shows the AC power supply.

Figure 1: SRX4600 Firewall AC Power Supply

Each AC power supply provides power to all components in the firewall. The two power supplies provide full power redundancy to the firewall. If one power supply fails or is removed, the second power supply 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.

For instructions on installing the power supply, see Installing the SRX4600 Firewall AC Power Supply.

Warning:

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. See Connecting Earth Ground to an SRX4600 Firewall.

Figure 2 shows the location of one bicolor LED on the faceplate of an AC power supply. This LED displays information about the status of the power supply.

Table 1 describes the LED on an AC power supply in an SRX4600 Firewall.

Table 1: AC Power Supply LED
LED State	Description
Unlit	Indicates one of the following: Power supply is disconnected from AC power feed. AC power input voltage is not within normal operating range. No AC power input.
Green	On steadily—Power supply is functioning normally.
Amber	Blinking—Power supply has failed.

DC Power Supply

The DC power supply is a FRU and you can install it without powering off the firewall or disrupting the firewall function.

Each DC power supply weighs approximately 4.4 lb (1.99 kg) and consists of a handle, an ejection lever, a status LED, and a terminal block that provides a single DC input (–48 VDC and return) that requires a dedicated customer-site circuit breaker. We recommend that you use a dedicated customer-site circuit breaker rated for 15 A (–48 VDC) minimum, or as required by local code. The DC power supply gives an output of 1100 W. Figure 3 shows the DC power supply.

SRX4600 Firewall AC Power Cord Specifications

A detachable AC power cord is supplied with the AC power supplies. 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.

Note:

In North America, AC power cords must not exceed 4.5 m (approximately 14.75 ft) in length, to comply with National Electrical code (NEC) Section 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the firewall are in compliance.

Table 4 provides power cord specifications, and Figure 5 depicts the plug on the AC power cord provided for each country or region.
