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 1 and Table 2 to calculate power consumption for various hardware configurations, and thermal output.
Table 1 lists the power requirements for base AC-powered devices operating under typical voltage conditions. It includes the efficiency for the AC power supplies.
Table 1: 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 2 lists the power requirements for various hardware components when the services gateway is operating under typical voltage conditions.
Table 2: Component Power Requirements
Component | Power Requirement (Watts) | Power Requirement (Watts) with 85% efficiency |
|---|---|---|
Fan tray (full speed) – Fan tray (normal speed) | 110 W – 80 W = 30 W | 35 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 |
These examples use generalized values per IOC and SPC.
Typical power consumption for AC-powered devices:
- Minimum AC-powered low-line
configuration @ 110 V:Base device (low-line nonredundant) + 1 SCB + 1 Routing Engine + 1 IOC—Generalized typical value + 1 SPC—Generalized typical value=180 W + 176 W + 106 W + 367 W + 251 W = 1080 W
- Maximum AC-powered low-line configuration @ 110 V:Base device (low-line redundant) + fan tray at full speed + 2 SCBs + 1 Routing Engine + 5 IOCs—Generalized maximum value + 1 SPC—Generalized maximum value=210 W + 35 W + 2(176) W + 106 W + (5)429 W + 413 W= 210 W + 35 W + 352 W + 106 W + 2145 W + 413 W = 3261 W
- Typical system thermal output (based
on maximally configured AC-powered services gateway @ 110 V input):Watts * 3.41 = BTU/hr 3261 W * 3.41 = 11,120 BTU/hr
- Minimum AC-powered high-line configuration
@ 220 V:Base device (high-line nonredundant) + 1 SCB + 1 Routing Engine + 1 IOC—Generalized typical value + 1 SPC—Generalized typical value=150 W + 176 W + 106 W + 367 W + 251 W = 1050 W
- Maximum AC-powered high-line configuration
@ 220 V:Base device (high-line redundant) + fan tray at full speed + 2 SCBs + 1 Routing Engine + 5 IOCs—Generalized maximum value + 1 SPC—Generalized maximum value =210 W + 35 W + 2(176) W + 106 W + (5)429 W + 413 W = 210 W + 35 W + 352 W + 106 W + 2145 W + 413 W = 3261 W
- Typical system thermal output (based on maximally configured
AC-powered services gateway @ 220 V input):Watts * 3.41 = BTU/hr 3261 W * 3.41 = 11,120 BTU/hr
