The ECS4100-28P/52P/12PH switches can provide DC power to a wide range of connected devices, eliminating the need for an additional power source and cutting down on the amount of cables attached to each device. Once configured to supply power, an automatic detection process is initialized by the switch that is authenticated by a PoE signature from the connected device. Detection and authentication prevent damage to non-compliant devices (prior to IEEE 802.3af).

The switch’s power management enables individual port power to be controlled within the switch’s power budget. Port power can be automatically turned on and off for connected devices, and a per-port power priority can be set so that the switch never exceeds its power budget. When a device is connected to a switch port, its power requirements are detected by the switch before power is supplied. If the power required by a device exceeds the power budget of the port or the whole switch, power is not supplied.

Ports can be set to one of three power priority levels, critical, high, or low. To control the power supply within the switch’s budget, ports set at critical to high priority have power enabled in preference to those ports set at low priority. For example, when a device connected to a port is set to critical priority, the switch supplies the required power, if necessary by denying power to ports set for a lower priority during bootup.

Note: For more information on using the PoE provided by this switch refer to the Installation Guide.

Setting the Switch’s Overall PoE Power Budget

Use the Administration > PoE > PSE (Configure Global) page to set the maximum PoE power budget for the switch (power available to all Gigabit Ethernet ports). If the power demand from devices connected to the switch exceeds the power budget, the switch uses port power priority settings to limit the supplied power.
