Appendix D: Power Guidelines, Requirements, and Specifications for the M10i Router
You can use the information in Table 22 on page 188 and the M10i 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. (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 PIC =
1.8 A + 0.625 A = 2.425 A @ 48 V = 116.4 W DC
Power consumption for maximum configuration:
Base system + 2 CFEBs + 8 PICs + second Routing Engine =
1.8 A + 2(1.4 A) + 8(0.625_A) + 0.7 A =
1.8 A + 2.8 A + 5_A + 0.7 A = 10.3 A @ 48 V = 494.4 W DC
Input current from a DC source other than 48 V (based on maximally configured router;
applies to DC power supply only):
(54 VDC input) x (input current X) = (48 VDC input) x (input current Y)
54 x X = 48 x 8.9 A
X = 48 x 8.9 A / 54 = 7.9 A
Example of calculating system thermal output for an AC-powered router:
Watts DC/65% AC PEM efficiency/0.293 = BTU/hr
494.4/0.65/0.293 = 2595.96 BTU/hr
Example of calculating System thermal output for aDC-powered router:
Watts DC/0.293 = BTU/hr
494.4/0.293 = 1687.37 BTU/hr
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.

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the
router. The C13 appliance coupler at the female end of the cord inserts into the AC
