Power Consumption for an AC-Powered MX80 Router
To allow for future growth so that you can operate the router in any hardware configuration without upgrading the power infrastructure, we recommend that you provision 6 A @ 110 VAC (660 W) or 3 A @ 220 VAC (660 W) for each input.
Table 1 and Table 2 list the power requirements for base AC-powered routers operating under typical voltage conditions.
If you do not plan to provision 6 A @ 110 VAC (660 W) or 3 A @ 220 VAC (660 W) for each input, you can use the information in Table 1, Table 2, and Table 3 to calculate the power consumption and thermal output for your hardware configuration.
Table 1: AC Base Router Power Requirements for the Fixed MX80 Router
Fixed Chassis Configuration | Power Requirement (Watts) | Power Requirement (Watts) with 85% Efficiency |
|---|---|---|
Chassis running at high activity, with four 10-Gigabit Ethernet XFPs, and fans running at high speed | 320 W | 376 W |
Table 2: AC Base Router Power Requirements for the Modular MX80 Router
Modular Chassis Configuration | Power Requirement (Watts) | Power Requirement (Watts) with 85% Efficiency |
|---|---|---|
Chassis running at high activity, with four 10-Gigabit Ethernet XFPs, two MICs, and fans running at high speed | 310 W | 365 W |
Table 3 lists the power requirements for various hardware components when the router is operating under typical voltage conditions.
Table 3: Component Power Requirements
Component | Power Requirement (Watts) | Power Requirement (Watts) with 85% Efficiency |
|---|---|---|
MIC (generalized value) | 35 W | 41 W |
These examples use generalized values per MIC. For exact MIC power requirements, see the MX Series 3D Universal Edge Routers Line Card Guide.
Typical power consumption for modular AC-powered routers @ 220 V (includes 85% efficiency):
- Active AC-powered router with one MIC:Base router (high activity, with four 10-Gigabit Ethernet XFPs, and fans running at high speed) + 1 MIC =282 W + 41 W = 323 W
- Active AC-powered router with two MICs:Base router (high activity, with four 10-Gigabit Ethernet XFPs, and fans running at high speed) + 2 MICs282 W + 2(41 W)= 364 W
- Example of calculating system thermal output:Watts AC PEM * 3.41 = BTU/hr 364 W * 3.41 = 1241 BTU/hr
