availability. However, the switch is most commonly used to segment existing hubs,
which nearly always improves the overall performances. An Ethernet Switching can
be easily configured in any Ethernet network environment to significantly boost
bandwidth using the conventional cabling and adapters.
Due to the learning function of the Industrial Gigabit PoE+ Switch, the source
address and corresponding port number of each incoming and outgoing packet are
stored in a routing table. This information is subsequently used to filter packets
whose destination address is on the same segment as the source address. This
confines network traffic to its respective domain and reduces the overall load on
the network.
The Industrial Gigabit PoE+ Switch performs "Store and Forward"; therefore, no
error packets occur. More reliably, it reduces the re-transmission rate. No packet
loss will occur.
4.5 Auto-Negotiation
The STP ports on the Industrial Gigabit PoE+ Switch have built-in “Auto-
negotiation”. This technology automatically sets the best possible bandwidth
when a connection is established with another network device (usually at Power
On or Reset). This is done by detecting the modes and speeds at the second of
both devices that are connected and capable of. Both 10BASE-T and 100BASE-TX
devices can connect with the port in either half- or full-duplex mode. 1000BASE-T
can be only connected in full-duplex mode.
