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.
Table 35: Base Device AC Power Requirements
Power Supplies | 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.
Table 36: Component Power Requirements for AC-Powered Devices
Component | Power Requirement (Watts) | Power Requirement (Watts) with 85% Efficiency |
|---|---|---|
Cooling system (full speed – normal speed) | 600 W – 400 W = 200 W | 235 W |
High-capacity fan tray | 320 W | 376 W |
SCB | 150 W | 176 W |
Routing Engine | 90 W | 106 W |
IOC—Generalized typical value | 312 W | 367 W |
IOC—Generalized maximum value | 365 W | 429 W |
SPC—Generalized typical value | 213 W | 251 W |
SPC—Generalized maximum value | 351 W | 413 W |
Typical power consumption for AC-powered devices:
- Power consumption for minimum
configuration:Base device and three power supplies + 2 SCBs + 1 Routing Engine + 1 IOC—Generalized typical value + 1 SPC—Generalized typical value=471 W + (2)176 W + 106 W + 367 W + 251 =471 W + 352 W + 106 W + 367 W + 251 = 1547 W
- AC Power consumption for maximum configuration:Base device and four power supplies + standard-capacity fan tray at full speed + 2 SCBs + 1 Routing Engine + 10 IOCs + 1 SPC—Generalized maximum value= 500 W + 235 W + 2(176 W) + 106 W + 10(429 W) + 413 W = 500 W + 235 W + 352 W + 106 W + 4290 W+ 413 W = 5896 W
- System thermal output for maximally configured AC-powered
services gateway:Watts DC* 3.41 = BTU/hr5896 W * 3.41 = 20,105 BTU/hr
