The static power management feature allows operators to reserve a guaranteed amount of power for a PoE port. This
is useful for powering up devices which draw variable amounts of power and provide them an assured power range
within which to operate.
In the Dynamic Power management feature, power is not reserved for a given port at any point of time. The power
available with the PoE switch is calculated by subtracting the instantaneous power drawn by all the ports from the
maximum available power. Thus, more ports can be powered at the same time.
PoE also provides a global usage threshold feature in order to limit the PoE switch from reaching an overload
condition.
Each of the three 2x4 RJ45 arrays has a companion PoE mezzanine connector with 2x20 pins.

Programming the Carrier ID (CID) with DIP switches
The Carried ID allows to define an unique system address for each RES2404-PTP-POE system. This feature can be
used to select predefined switch configurations based on programmed system address.
See corresponding “boot autoinstall file“ commands in the RES-PTP-POE CLI Reference Manual.
Figure 10: Rotary DIP switches
The 8 bit address can be programmed by turning the rotary switches.
