  • Management features
    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
    Switch type*
    What switch device has managed or unmanaged.
    Managed
    Web-based management
    Using a website/web application to manage something.
    Yes
    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 ports quantity*
    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 slots ('ports') for SFP connections in a device.

    Networking
    Networking standards*
    The way in which the network is working e.g. IEEE 802.11a IEEE 802.11b IEEE 802.11g.
    IEEE 802.3 IEEE 802.3ab IEEE 802.3u
    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.
    Yes
    IGMP snooping
    Yes
    Port mirroring
    Yes
    Flow control support
    Yes
    Link aggregation
    Yes
    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.
    Yes
    Spanning tree protocol
    Yes
    DHCP server
    A server is a system which that responds to requests across a computer network to provide or help to provide a network service. DCHP servers uses the DCHP (Dynamic Host Configuration Protocol) which is a standardized networking protocol used by servers on an IP network to allocate IP addresses to computers. The purpose of DHCP is to automate the IP address configuration of a computer without a network administrator. IP addresses are typically selected from a range of assigned IP addresses stored in a database on the server and issued to a computer which requests a new IP address. An IP address is assigned to a computer for a set interval after which the computer must renew the IP address or acquire a new one.
    Yes
    DHCP client
    Yes
    Rate limiting
    Yes
    10G support*
    The product can use Oracle 10G which is a database management system introduced in 2003.
    Yes
    Data transmission
    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.
    16384 entries
    Switching capacity*
    The data transfer capacity of the switch per second.

    Design
    Rack mounting *
    The type of mounting that can position devices in a shelving system (rack).
    Yes
    Colour of product *
    The colour e.g. red blue green black white.
    Grey
    Performance
    Built-in processor
    MIPS
    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.
    650 MHz
    Internal memory
    The amount of memory usually measured in bytes (e.g. MB GB) which is installed in the system's hardware.
    128 MB
    Packet buffer memory
    12 MB
    Flash memory
    32 MB
    Memory type
    Type of memory in the device e.g. DDR3 SRAM (Static RAM).
    SDRAM
    Power
    AC input voltage
    The voltage of the AC electricity that is inpitted into the product.
    100-240 V
    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.
    32 W
    Power over Ethernet (PoE)
    Power over Ethernet (PoE) support *
    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.
    Yes
