D-Link DES-3052P Managed 48-Port PoE Stackable Switch 

D-Link DES-3052P Managed 48-Port PoE Stackable Switch is a versatile switch with 48 Fast Ethernet ports, four Gigabit Ethernet ports, and two SFP ports. Each of the 10/100 ports are Power-over-Ethernet (PoE) compliant, allowing PoE devices connected to them to be powered even in the absence of another power source.

Virtual stacks consisting of up to 32 switches allow for an incredible number of ports to be managed from a single IP address, and the rack mountable design allows the switch to easily be added to a rack.
