PLANET ISW-621TF is an Industrial Ethernet Switch that can operate under temperature environment ranging from -40 up to 75 degrees C and is equipped with 4 10/100 Ethernet and 2 100Base-FX SFP ports. The two SFP interfaces allow transmission to be extended from 2 kilometers (via multi-mode fibre) up to 60 kilometres (via single-mode fiber).

Physical Port
– 4-port 10/100Base-TX RJ-45 with auto MDI/MDI-X function
– 2-port 100Base-FX SFP interface

Layer 2 Features
– Complies with IEEE 802.3, IEEE 802.3u 10/100Base-TX, 100Base-FX Ethernet standard
– Supports auto negotiation and 10/100Mbps half / full duplex mode for each copper port
– High performance Store and Forward architecture
– Prevents packet loss with back pressure (half-duplex) and IEEE 802.3x pause frame flow control (full-duplex)
– Backplane (Switching Fabric): 1.2Gbps
– Integrated address look-up engine, supporting 2K absolute MAC addresses
