The ISW-804PT-M12, the Industrial 8-Port 10/100Mbps M12 PoE Fast Ethernet Switch, is designed with the IP67 industrial case, providing a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control cabinets. The compact, IP67 standard metal case of the ISW-804PT-M12 allows either DIN rail or wall mounting installation for efficient use of cabinet space.The ISW-804PT-M12 is equipped with 8-port 10/100Base-TX auto-negotiation M12 connector with 4-port IEEE 802.3af PoE (Port 5 to port 8); each PoE port provides 15.4-watt PoE output. The M12 connector provides tight and strong connection and guarantees stable Ethernet operation performance under high vibration and shock environment.Being able to operate under the temperature range from -40 to 75 degrees C, the ISW-804PT-M12 can be placed in almost any difficult environment. The ISW-804PT-M12 also possesses an integrated power supply source with wide range of voltages (48V DC) for worldwide high availability applications requiring dual or backup power inputs.The ISW-804PT-M12 has 2K MAC Address table and offers wire-speed packets transfer performance without risk of packet loss; the high data throughput of the device makes it ideal for most Fast Ethernet environments. With a 1.6Gbps internal switching fabric and featuring auto negotiation support in each of the eight Fast Ethernet port, the ISW-804PT-M12 can handle large amounts of data in a secure topology linking to a backbone or high capacity servers.The flow control function enables the ISW-804PT-M12 to provide fast and reliable data transfer. All of the M12 RJ-45 copper interfaces in the ISW-804PT-M12 support 10/100Mbps auto-negotiation for optimal speed detection through RJ-45 category 3, 4, 5, 5e, 6 cables. The standard auto-MDI/MDI-X support can detect the type of connection to any Ethernet device without requiring special straight or crossover cables.
