Power Requirements For Ac-Powered Srx1400 Services Gateways - Juniper SRX1400 Hardware Manual

Power Requirements for AC-Powered SRX1400 Services Gateways

If you do not plan to provision 6 A at 240 VAC for the system, you can use the information
in Table 47 on page 189 and Table 48 on page 190 to calculate power consumption for
various hardware configurations, and thermal output.
Table 47 on page 189 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
Table 48 on page 190 lists the power requirements for various hardware components
when the services gateway is operating under typical voltage conditions.

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.
Component
Nonredundant configuration includes AC power supply, backplane,
SYSIOC, Routing Engine, and the fan tray.
Redundant configuration includes two AC power supplies, backplane,
SYSIOC, Routing Engine, and the fan tray.
NOTE: The power requirement values shown in Table 47 on page 189 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.
