Power management modes
A powered device is classified based on the maximum power that it draws across all
input voltages and operational modes. When class-based power management mode is
configured on the ACX2000 routers, power is allocated taking into account the maximum
power ratings defined for the different classes of devices.
Table 20 on page 143 lists the classes and their power ratings as specified by the IEEE
standards.
