SRX1600 Power System

The SRX1600 is powered by two power supplies for 1 + 1 redundancy. The SRX1600 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 SRX1600 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 PSU. We recommend that you use a 10 A (250 VAC), or as permitted by the local code.

Supported AC Power Cords

Warning:

Use the AC power cord with the firewall only and not for any other purpose.
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 3 provides power cord specifications, and Figure 2depicts the plug on the AC power cord provided for each country or region.
