Netgear GS748T ProSafe 48-Port Gigabit Smart 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).	L3
Quality of Service (QoS) support
Web-based management Using a website/web application to manage something.

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-negotiation
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.
Virtual LAN features	Tagged VLAN
Number of VLANs	256

Data transmission
Switching capacity The data transfer capacity of the switch per second.	100 Gbit/s
Forwarding rate	74.4 Mpps
MAC address table The MAC address is the 'Media Access Control Address'. It is a unique address given to a network interface controller (NIC) in a device. A MAC address table shows the addresses in a table format.	16000 entries
Store-and-forward
Latency (1 Gbps)	4.4 µs
Number of queues	8
Jumbo frames support
Jumbo frames	9216

Design
Rack mounting The type of mounting that can position devices in a shelving system (rack).
Product colour The colour e.g. red, blue, green, black, white.	Gray
Housing material What the casing of the product is made of.	Metal
Certification	VCCI Class A

Performance
Internal memory The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.	128 MB
Flash memory	32 MB
Noise level The amplitude level of the undesired background noise, usually measured in decibels (db).	37.2 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.	390728 h

Power
AC input voltage The voltage of the AC electricity that is inputted into the product.	100 - 240 V
AC input frequency	50 - 60 Hz
Power consumption (typical) Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.	41.1 W

Power over Ethernet (PoE)
Power over Ethernet (PoE) The device supports Power over Ethernet (PoE), which is one of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.

Operational conditions
Operating temperature (T-T) The minimum and maximum temperatures at which the product can be safely operated.	0 - 50 °C
Storage temperature (T-T) The minimum and maximum temperatures at which the product can be safely stored.	-20 - 70 °C

Weight & dimensions
