M10i Router Power Requirements

 

Table 1 lists the power requirements for various hardware components when the router is operating under typical voltage conditions. For PIC power requirements, see the M10i Multiservice Edge Router Interface Module Reference.

You can use the information in Table 1 and the M10i Multiservice Edge Router Interface Module Reference to calculate power consumption for various hardware configurations, input current from a different source voltage, and thermal output, as shown in the following examples. (The examples use a generalized value for PICs of 0.625 A @ 48 V each.)

  • Power consumption for minimum configuration:

  • Power consumption for maximum configuration:

  • Input current from a DC source other than 48 V (based on maximally configured router; applies to DC power supply only):

  • Example of calculating system thermal output for an AC-powered router:

  • Example of calculating System thermal output for aDC-powered router:

    Note

    We recommend that you provision at least 9.1 A @ 48 VDC and use a facility circuit breaker rated for 15 A minimum. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure, and allows the router to function at full capacity using multiple power supplies.
