How many devices can be powered?

Plasma Cloud switches support 802.3af and 802.3at PoE standards. Each port comes with the capability to detect the PoE standard required by the connected device. Therefore, a mix of 802.3af and 802.3at power consumers can be powered.

The amount of power supplied on each PoE port may vary greatly depending on power consumption of the connected device. To give an example: although the PA300 uses 802.3af PoE standard, its actual power consumption is 11.5 W or less (depending on system load and cable length). Consequently, a PS24-L allows to power up to 21x PA300 despite the PoE standard defining a power consumption of 15.4 W.

When the exact power consumption is not available, refer to the PoE standard (802.3af: 15.4 W, 802.3at: 30 W) to estimate the number of devices that can be powered through this PoE switch.

Power over Ethernet

Power over Ethernet (PoE) allows you to combine data transfer and power supply using a single Ethernet cable which terminates in a PoE switch. Thereby, cabling effort can be reduced and power management of all connected devices greatly simplified. Combined with the powerful Plasma Cloud console, all connected devices can be centrally managed, power consumption monitored, power schedules automated and even non-Plasma Cloud devices power cycled when needed.

Almost all networking equipment today supports PoE, including WiFi Access Points, IP cameras, VoIP phones, and many more IoT devices. This allows for easy installation since PoE enables you to place devices in locations removed from power outlets (up to 100m Ethernet cable length).
