About WS-C3750X-48U-E

Product Overview

The Cisco Catalyst WS-C3750X-48U-E is an enterprise-class networking switch. It is provided with the Power over Ethernet Plus (PoE+) technology support and Media Access Control Security (MACsec) features. The 3750-X is a stackable version that supports Cisco StackPower as well.

Power Supply

The switch has a 1100 W redundant AC power supply and an additional slot for another 1100 W power supply in case power consumption of the network is too high.

Power Capacity

WS-C3750X-48U-E has 48 Universal Power over Ethernet switches. It is a new Cisco PoE technology that allows every port to distribute up to 30 W of power, which is twice as powerful as that of PoE technology (15 W). In general, the switch can provide up to 800 W of power to other devices.


The switch comes with 48 10/100/1000 Ethernet UPOE ports and a 1100 AC power supply. The switch can be mounted into 1 unit rack kit (1 RU). The IP Services feature license has everything you need to conduct switching operations for your network.


The WS-C3750X-48U-E is a stackable switch that supports StackWise technology. The stack can combine up to 9 switches into a single unit. This means that there are no delays or packet losses due to the fact that the unit chooses a master switch and the whole systems works like a single switch afterward. StackPower is another technology used by this model. This feature makes the distribution of power between the devices connected to the switching unit much more efficient. It stops providing power when the device is not used or helps other switches when they are overloaded.
