Power Requirements for AC-Powered SRX1400 Services Gateways

 Note

If you plan to operate a maximally configured AC-powered services gateway, we recommend that you provision 6 A at 240 VAC for the system.

If you do not plan to provision 6 A at 240 VAC for the system, you can use the information in Table 1 and Table 2 to calculate power consumption for various hardware configurations, and thermal output.

Table 1 lists the power requirements for base AC-powered devices operating under typical voltage conditions. It includes the efficiency for the AC power supplies.

Table 1: Base System AC Power Requirements

Component

Power Requirement (Watts)

Nonredundant configuration includes AC power supply, backplane, SYSIOC, Routing Engine, and the fan tray.

210 W (approximate)

Redundant configuration includes two AC power supplies, backplane, SYSIOC, Routing Engine, and the fan tray.

222 W (approximate)

Note

The power requirement values shown in Table 1 are for a lightly loaded system. For a heavily loaded system, the contribution of the base system to the overall system power requirement is lower, because the power supply efficiency improves as the load increases. For a heavily loaded system, both the redundant and nonredundant base systems contribute approximately 210 W to the overall system power requirement.

Note

In SRX1400 Services Gateways with 1-Gigabit Ethernet System I/O card, the base system power requirement is less by 5 to 6 watts than the base system power requirement for the SRX1400 devices with 10-Gigabit Ethernet System I/O card.

Table 2 lists the power requirements for various hardware components when the services gateway is operating under typical voltage conditions.

Use the information in Table 1 and Table 2 to calculate power consumption for various hardware configurations, input current from a different source voltage, and thermal output, as shown in the following examples. These examples use maximum values per IOC.

Typical power consumption for AC-powered devices:

  • Minimum AC-powered configuration:

  • Maximum AC-powered configuration:

  • Typical system thermal output (based on maximally configured AC-powered services gateway at 110 V input):
