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 47 and Table 48 to calculate power consumption for various hardware configurations, and thermal output.

Table 47 lists the power requirements for base AC-powered devices operating under typical voltage conditions. It includes the efficiency for the AC power supplies.

Table 47: 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 47 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 48 lists the power requirements for various hardware components when the services gateway is operating under typical voltage conditions.

Use the information in Table 47 and Table 48 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.
