Dell PowerSwitch S4128T 28x10GBase-T Managed Switch

Management features
Switch type What switch device has, managed or unmanaged.	Managed
Switch layer A network switch is a computer networking device that links networking segments. A switch has different layers, such as layer 2 (a network bridge, operating at the data link layer, interconnecting a small number of devices) and layer 4 (can act as a firewall, amongst other things).	L2/L3
Quality of Service (QoS) support
Configuring Location Settings (CLI)

Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity The number of basic switching RJ-45 Ethernet ports (sockets).	28
Basic switching RJ-45 Ethernet ports type The type/category of basic switching RJ-45 Ethernet ports (sockets).	10G Ethernet (100/1000/10000)
Installed QSFP+ modules quantity	2
Fiber optic connector This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.	QSFP28
Power connector	AC-in jack

Network
10G support The product can use Oracle 10G, which is a database management system introduced in 2003.
VLAN support A Virtual Local Area Network (VLAN) consists of a group of computers and switches that can be physically distributed over different networks and buildings, but form one LAN on a logical level.
