Power Consumption for an AC-Powered SRX5800 Services Gateway

We recommend that you provision 11 A  @ 240 VAC for each input.

If you do not plan to provision 11 A  @ 240 VAC for each input, you can use the information in Table 35 and Table 36 to calculate the power consumption and thermal output for your hardware configuration.

Table 35 lists the power requirements for base AC-powered services gateways operating under typical voltage conditions and includes nonredundant and redundant power supply configurations.

Services Gateway Configuration

Power Requirement (Watts)

Standard-capacity

Nonredundant AC configuration includes three standard-capacity AC power supplies, the midplane, craft interface, and fan trays (running at normal speed)

471 W (approximate)

Redundant AC configuration includes four standard-capacity AC power supplies, the midplane, craft interface, and fan trays (running at normal speed)

500 W (approximate)

High-capacity

Nonredundant AC configuration includes two high-capacity AC power supplies, the midplane, craft interface, and fan trays (running at normal speed)

588 W (approximate)

Redundant AC configuration includes four high-capacity AC power supplies, the midplane, craft interface, and fan trays (running at normal speed)

708 W (approximate)

Table 36 lists the power requirements for various hardware components under typical voltage conditions.
