Netgear GSM4352PB 48-Port Fully Managed Stackable Layer 3 PoE+ Switch 1000W Power Supply Unit

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/L4
Quality of Service (QoS) support
Web-based management Using a website/web application to manage something.
ARP inspection

Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity The number of basic switching RJ-45 Ethernet ports (sockets).	48
Basic switching RJ-45 Ethernet ports type The type/category of basic switching RJ-45 Ethernet ports (sockets).	Gigabit Ethernet (10/100/1000)
SFP+ module slots 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.	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

Rate limiting
Auto MDI/MDI-X A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDIX) interface. Auto-MDIX ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDIX configuration to properly match the other end of the link.
Spanning tree protocol
Auto-sensing
Auto-negotiation

Performance
Built-in processor Whether or not a processor is built into the device.
Processor frequency The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.	800 MHz
Internal memory The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.	1024 MB
Flash memory	256 MB
Noise level The amplitude level of the undesired background noise, usually measured in decibels (db).	39.8 dB
Mean time between failures (MTBF) Statistical model used to indicate product/mechanism reliability; expressed in hours and percentage of duty cycle. This number (in hours) does not indicate the mean time before failure for a single unit/mechanism.	673207 h

Power
Power source What is providing power for the product e.g. mains electricity.	AC
Power supply included There is a power supply with this product.
Redundant power supply (RPS) support Additional power supply which can run a computer if the main power supply fails.
