Power Consumption for an AC-Powered SRX5600 Services Gateway

We recommend that you provision 11.0 A @ 200 VAC (2200 W) or 14.5 A @ 110 VAC (1595 W) for each input.

If you do not plan to provision 11.0 A @ 200 VAC (2200 W) or 14.5 A @ 110 VAC (1595 W) for each input, you can use the information in Table 31 and Table 32 to calculate power consumption for various hardware configurations, and thermal output.

Table 31 lists the power requirements for base AC-powered devices operating under typical voltage conditions. It includes the efficiency for the AC power supplies.

Table 31: Base System AC Power Requirements

Component

Power Requirement (Watts)

Low-line nonredundant configuration @ 110 V includes three AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

180 W (approximate)

Low-line redundant configuration @ 110 V includes four AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

210 W (approximate)

High-line nonredundant configuration @ 220 V includes two AC power supplies, one Routing Engine, one SCB, midplane, craft interface, and the fan tray (running at normal speed)

150 W (approximate)

High-line redundant configuration @ 220 V includes four AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

210 W (approximate)

Table 32 lists the power requirements for various hardware components when the services gateway is operating under typical voltage conditions.
