Table 18 on page 163 lists the power requirements for various hardware components when
the router is operating under typical voltage conditions. For PIC power requirements, see
the M7i Multiservice Edge Router PIC Guide.

Base system (cooling system, power supplies, and FIC)
CFEB/CFEB-E
CFEB/CFEB-E with Adaptive Services Module
CFEB-E with MultiServices Module
Routing Engine
You can use the information in Table 18 on page 163 and the M7i Multiservice Edge Router
PIC Guide to calculate power consumption for various hardware configurations, input
current from a different source voltage, and thermal output, as shown in the following
examples. (For an added safety margin, the examples use a generalized value for PICs
of 0.625 A @ 48 V each.)
Power consumption for minimum configuration:
Base system + 1 CFEB + 1 RE + 1 PIC =
0.6 A + 1.4 A + 0.7 A + 0.625 A = 3.3 A @ 48 V = 159 W DC
