Switch Management Commands 2020
Assuming a maximum current draw of 31.2W per device and the default
settings for PoE, the N2024P can power 32 devices using a single power
supply and the N2048P can power 31 devices with a single power supply and
48 devices when using two power supplies. The guard band used when
powering up a port varies depending upon the following factors:
a
Power management mode
b
Class of the device being powered up.
The power management mode is configured using the power inline
management command. The guard band for a Class 0 or Class 4 device may
be configured with the power inline usage-threshold command. The user
defined power limit can be found with the show power inline detailed
command. The power limit is used as a guard band when powering up a port.
If the remaining available power is less than the guard band, the device is not
powered up. By default, the guard band is 32 watts.
Regardless of the power management mode, if the device being powered up is
a Class 1, 2 or 3 device, then the guard band is configured according to the
device class.
Dynamic or Static Power Management Mode
In this mode, the guard band for the port being powered up is:
For Class 0 device: User defined power limit.
For Class 1 device: 4 watts
For Class 2 device: 7 watts
