Power Budget
Power budget is the maximum amount of power that the PoE switch can provide at one
time to the connected PDs. Port Prioritization As long as the total power requirements
of the PDs is less than the total available power of the switch, it can supply power to all
of the PDs.
However, when the PD power requirements exceed the total available power, the
switch denies power to some ports based on a process called port prioritization.
The ports on the PoE switch are assigned to one of three priority levels. These levels and
descriptions are listed in Table 3. Without enough power to support all the ports set to
the same priority level at one time, the switch provides power to the ports based on the
port number, in ascending order. For example, when all of the ports in the switch are set
to the low priority level and the power requirements are exceeded on the switch, port 1
has the highest priority level, port 2 has the next highest priority level and so forth.
Priority Level
This is the highest priority level. Ports set to
the Critical level are guaranteed to receive
Critical
power before any of the ports assigned to
the other priority levels.
Ports set to the High level receive power
High only when all the ports assigned to the
Critical level are already receiving power.
This is the lowest priority level. Ports set to
the Low level receive power only when all
Low the ports assigned to the Critical and High
levels are already receiving power. This
level is the default setting.
