SRX4300 Power System

The SRX4300 is powered by two power supplies for 1 + 1 redundancy. The SRX4300 has hot-removable and hot-insertable power supply units (PSUs). If one PSU fails, you can replace it without powering off or disrupting the device function. The second PSU balances the electrical load without interruption. A fan in each power supply provides cooling.

Note:

We ship the SRX4300 with only one PSU. You can order the second PSU separately if required.
CAUTION:

You must not mix AC and DC power supplies in the same chassis.

You must use a dedicated external circuit breaker for each power supply. We recommend that use a 16 A (250 VAC) minimum, or as permitted by the local code.

Supported AC Power Cords

Warning:

The AC power cord for the firewall is intended for use with the firewall only and not for any other use.
Note:

In North America, AC power cords must not exceed a length of 4.5 m (approximately 14.75 ft). This length complies 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).

Table 4 provides power cord specifications, and Figure 2 depicts the plug on the AC power cord provided for each country or region.

Callout LED Color Description
1 AC Off No power input.
Green PSU is operating normally.
2 DC Off No power output.
Green PSU is operating normally.
3 Fault Amber The system has detected an error in the PSU. Replace the PSU immediately. To maintain proper airflow thorugh the chassis, leave the PSU installed in the chassis until you are ready to replace it.
