PS48 PoE Switch

__________

The PS48 full power rack mount switch is a professional solution to power very large amounts of PoE devices. With its 48x 1 Gigabit Ethernet ports and a PoE budget of 740 W, it can comfortably power up to 48x 802.3af devices or 24x 802.3at devices at the same time. 4x SFP+ transceiver slots provide 10 Gbps connectivity per slot to the optical fiber network. The backplane switching capacity of 176 Gbps allows to max out the Gigabit throughput on all Ethernet ports without hitting any bottleneck.

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 PS48 allows to power up to 48x 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.

Mounting options

The included mounting brackets offer to mount the PS48 onto a rack or wall. It also can be positioned on a desk or shelf.

PoE

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).
