Output power in watts / power supply efficiency @90% = power consumption in watts
1736 W / 0.9 = 1929 W
The following calculations show the maximum power consumption (at 55° C) for modularrouters :
•
Fully loaded AC-powered router with four fan modules, two MPCs, two JNP-MIC1 MICs, and two RCBs:
Router (idle at 55° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs=
380 W + 1430 W + 170 W + 130 W = 2110 W
Output power in watts / power supply efficiency @90% = power consumption in watts
2110 W / 0.9 = 2345 W
•
Fully loaded AC-powered router with four fan modules, two MPC, two JNP-MIC1-MACSEC MICs, and
two RCBs:
Router (idle at 55° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs=
380 W + 1430 W + 240 W + 130 W = 2180 W
Output power in watts / power supply efficiency @90% = power consumption in watts
2180 W / 0.9 = 2422 W
Table 27 on page 72 lists the power requirements for the fully configured routers operating under typical
voltage conditions.
