7705 SAR-M Power Consumption
Table 7 lists the power consumption estimates for each variant of the 7705 SAR-M chassis,
with no module installed in those variants equipped with module slots.
For those variants equipped with module slots, installing a module increases the average and
maximum power draw of the chassis. When planning the installation of a module, see Module
Power Consumption for information about the estimated power draw.
