Specifications
Management features
What switch device has, managed or unmanaged.  Switch type Managed  
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 L2/L3  
Quality of Service (QoS) support Yes  
Using a website/web application to manage something.  Web-based management Yes  
Cloud-managed Yes  
ARP inspection Yes  
Configuring Location Settings (CLI) Yes  
MIB support Yes  
Ports & interfaces
The number of basic switching RJ-45 Ethernet ports (sockets).  Basic switching RJ-45 Ethernet ports quantity 48  
The type/category of basic switching RJ-45 Ethernet ports (sockets).  Basic switching RJ-45 Ethernet ports type Gigabit Ethernet (10/100/1000)  
An SFP ("small form-factor pluggable transceiver") is a transmitter/receiver which interfaces a network device motherboard (e.g. in a switch, router) to a fibre optic or copper network cable. The "SFP ports quantity" is the number of ports for SFP connections in a device.  Installed SFP modules quantity 4  
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.  USB 2.0 ports quantity 1  
Network
The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.  Networking standards IEEE 802.1D, IEEE 802.1Q, IEEE 802.1ad, IEEE 802.1af, IEEE 802.1p, IEEE 802.1s, IEEE 802.1w, IEEE 802.1x, IEEE 802.3, IEEE 802.3ab, IEEE 802.3ad, IEEE 802.3u  
Port mirroring Yes  
Flow control support Yes  
Broadcast storm control Yes  
The different speed levels of the Ethernet LAN connection.  Ethernet LAN data rates 1000 Mbit/s  Mbit/s
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 Yes  
Spanning tree protocol Yes  
Head-of-line (HOL) blocking 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 Yes  
Number of VLANs 255  
Data transmission
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 8000 entries  
Jumbo frames support Yes  
Jumbo frames 9000  
Security
DHCP features DHCP relay, DHCPv6 client  
Access Control List (ACL) Yes  
Access Control List (ACL) rules 512  
IGMP snooping Yes  
Security algorithms are used to provide authentication, cipher key generation, integrity and radio link privacy to users on mobile networks. The security algorithms supported are the ones that can be used with this product.  Security algorithms HTTPS, SSH, SSL/TLS  
Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.  MAC address filtering Yes  
SSH/SSL support Yes  
The computer, smartphone etc. can only be used when the correct password is entered, therefore making it more secure.  Password protection Yes  
Multicast features
Multicast support Yes  
Protocols
Management protocols SNMP  
Design
The type of mounting that can position devices in a shelving system (rack).  Rack mounting Yes  
The colour e.g. red, blue, green, black, white.  Product colour Silver  
Reset button Yes  
LED indicators Yes  
Performance
Built-in processor Yes  
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 800 MHz  MHz
The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.  Internal memory 512 MB  MB
Flash memory 256 MB  MB
Firmware upgradeable Yes  
Harmonized System (HS) code 85176990  
Power
There is a power supply with this product.  Power supply included Yes  
AC input frequency 50/60 Hz
