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).	L3
Quality of Service (QoS) support
Web-based management Using a website/web application to manage something.

Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity The number of basic switching RJ-45 Ethernet ports (sockets).	20
Basic switching RJ-45 Ethernet ports type The type/category of basic switching RJ-45 Ethernet ports (sockets).	Gigabit Ethernet (10/100/1000)
Combo SFP ports quantity	4

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.	SFP+
Console port	RJ-45/Mini-USB
USB 2.0 ports quantity Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.	1
