Power Consumption for an AC-Powered MX480 Router
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.
For high capacity power supplies, we recommend that you provision 16A @ 200V and or 16 A @ 100 VAC for each input.
Table 1 lists the power requirements for base AC-powered routers operating under typical voltage conditions. It includes the efficiency for the AC power supplies.

Table 2 lists the power requirements for various hardware components when the router 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 |
High-capacity fan tray | 160 W | 188 W |
SCB | 150 W | 176 W |
Routing Engine | 90 W | 106 W |
DPC—Generalized typical value | 312 W | 367 W |
DPC—Generalized maximum value | 365 W | 429 W |
FPC2 (without PICs) | 110 W | 129 W |
FPC3 (without PICs) | 180 W | 212 W |
MPC (fixed configuration) | 440 W | 518 W |
MPC (without MICs) | 294 W | 346 W |
These examples use generalized values per DPC. For exact DPC, MPC, MIC, and PIC power requirements, see the MX Series 3D Universal Edge Routers Line Card Guide.
Typical power consumption for AC-powered routers:
- Minimum AC-powered low-line
configuration @ 110 V:Base router (low-line nonredundant) + 1 SCB + 1 Routing Engine + 1 DPC—Generalized typical value =180 W + 176 W +106 W + 367 W = 729 W
- Maximum AC-powered low-line configuration @ 110 V:Base router (low-line redundant) + fan tray at full speed + 2 SCBs + 2 Routing Engines + 6 DPCs—Generalized maximum value =210 W + 35 W + 2(176) W + 2(106) W + (6)429 W = 210 W + 35 W + 352 W + 212 W + 2574 W = 3383 W
- Minimum AC-powered high-line configuration
@ 220 V:Base router (high-line nonredundant) + 1 SCB + 1 Routing Engine + 1 DPC—Generalized typical value =150 W + 176 W +106 W + 367 W = 799 W
- Maximum AC-powered high-line configuration
@ 220 V:Base router (high-line redundant) + fan tray at full speed + 2 SCBs + 2 Routing Engines + 6 DPCs—Generalized maximum value =210 W + 35 W + 2(176) W + 2(106) W + (6)429 W = 210 W + 35 W + 352 W + 212 W + 2574 W = 3383 W
- Example of calculating system thermal output:Watts * 3.41 = BTU/hr 3383 W * 3.41 = 11,536 BTU/hr
