Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
48-port 10/100 MultiIayer IPv4/IPv6 Switch
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.
Category :
A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.

Data-sheet quality: created/standardized by Icecat
The quality of the product data-sheet can be on several levels:
only logistic data imported: we have only basic data imported from a supplier, a data-sheet is not yet created by an editor.
created by Allied Telesis: a data-sheet is imported from an official source from a manufacturer. But the data-sheet is not yet standardized by an Icecat editor.
created/standardized by Icecat: the data-sheet is created or standardized by an Icecat editor.

Management features
Switch type*
What switch device has, managed or unmanaged.
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).
Quality of Service (QoS) support
Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity*
The number of basic switching RJ-45 Ethernet ports (sockets).
SFP/SFP+ slots quantity
SFP module slots quantity
DC-in jack
The socket/plug where the DC electricity supply connects to the device.
Networking standards*
The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.
IEEE 802.1D, IEEE 802.1Q, IEEE 802.1v, IEEE 802.2, IEEE 802.3ab, IEEE 802.3ac, IEEE 802.3ad, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z
Full duplex
A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.
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.
DHCP client
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.
262144 entries
Switching capacity*
The data transfer capacity of the switch per second.
37.6 Gbit/s
Maximum data transfer rate
0.1 Gbit/s
MAC address filtering
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.
Management protocols
Rack mounting*
The type of mounting that can position devices in a shelving system (rack).
Form factor
The shape or design of the product.
Colour of product*
The colour e.g. red, blue, green, black, white.

128 MB
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.
300000 h
