Descriptions
Management features
Managed What switch device has, managed or unmanaged. Switch type
L3 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). Switch layer
YesQuality of Service (QoS) support
Yes Using a website/web application to manage something. Web-based management
Ports & interfaces
48 The number of basic switching RJ-45 Ethernet ports (sockets). Basic switching RJ-45 Ethernet ports quantity
Gigabit Ethernet (10/100/1000) The type/category of basic switching RJ-45 Ethernet ports (sockets). Basic switching RJ-45 Ethernet ports type
4 An SFP ( Installed SFP modules quantity
10BASE-T,100BASE-TX,1000BASE-TCopper ethernet cabling technology
Networking
IEEE 802.3,IEEE 802.3ab,IEEE 802.3u,IEEE 802.3z The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g. Networking standards
Yes A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously. Full duplex
YesFlow control support
YesPort mirroring
YesRate limiting
YesDHCP client
YesIGMP snooping
Yes 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. Auto MDI/MDI-X
YesSpanning tree protocol
No The product can use Oracle 10G, which is a database management system introduced in 2003. 10G support
Yes 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. VLAN support
YesAuto-sensing
Data transmission
104  Gbit/s The data transfer capacity of the switch per second. Switching capacity
77.3  MppsThroughput
16000  entries 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. MAC address table
7  µsLatency (10-100 Mbps)
2  µsLatency (1 Gbps)
YesJumbo frames support
Security
YesAccess Control List (ACL)
YesSSH/SSL support
Design
Yes The type of mounting that can position devices in a shelving system (rack). Rack mounting
1U The shape or design of the product. Form factor
Grey The colour e.g. red, blue, green, black, white. Colour of product
Performance
Yes Devices can be placed on top of each other. Stackable
YesBuilt-in processor
400  MHz 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. Processor frequency
256  MB The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware. Internal memory
SDRAM Type of memory in the device e.g. DDR3, SRAM (Static RAM). Memory type
64  MBFlash memory
1.5  MBPacket buffer memory
Power
100-240  V The voltage of the AC electricity that is inpitted into the product. AC input voltage
50/60  HzAC input frequency
54.8  W 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. Power consumption (typical)
481  W The maximum amount of power used by the device. Power consumption (max)
Power over Ethernet (PoE)
Yes 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. Power over Ethernet (PoE)
370  WTotal Power over Ethernet (PoE) budget
Operational conditions
0 – 40  °C The minimum and maximum temperatures at which the product can be safely operated. Operating temperature (T-T)
-40 – 70  °C The minimum and maximum temperatures at which the product can be safely stored. Storage temperature (T-T)
15 – 95  %Operating relative humidity (H-H)
15 – 95  %Storage relative humidity (H-H)
Weight & dimensions
442.5  mm The measurement or extent of something from side to side. Width
246.1  mm The distance from the front to the back of something. Depth
43.9  mm The measurement of the product from head to foot or from base to top. Height
4400  g Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies. Weight
