PLANET ISW-1600T Industrial high-density 16-port 10/100TX Fast Ethernet Switch is equipped with a rugged IP30 metal case for stable operation in heavy industrial demanding environments. Thus, the ISW-1600T provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curbside traffic control cabinets. Environmentally Hardened Design The ISW-1600T possesses an integrated power supply source with a wide range of voltages (12 to 48V DC or 24V AC) for worldwide high availability applications requiring dual or backup power inputs. Being able to operate under wide temperature range from -40 to 75 degrees C, the ISW-1600T can be placed in almost any difficult environment. The ISW-1600T also allows either DIN rail or wall mounting for efficient use of cabinet space. Robust Protection The ISW-1600T provides a contact discharge of ±6KV DC and air discharge of ±6KV DC for Ethernet ESD protection. It also supports ±6KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.   Energy Saving The ISW-1600T, integrated with advanced green networking technologies and IEEE 802.3az protocol based power saving, is able to provide power savings of up to 50% but maintain high performance efficiently. Link Down power saving The Link Down power saving goes beyond IEEE specifications to automatically lower power consumption for a given port when it is not linked. With the Link Down power saving technology, the ISW-1600T will automatically adjust power usage of the ports that are shut down or not connected to network device. Intelligent power scale based on cable length Intelligent power scale is an intelligent algorithm that actively determines the appropriate power level based on cable length. When the ISW-1600T is connected with Ethernet cable shorter than 20m, a device can obtain maximum power saving because the ISW-1600T would automatically detect the Ethernet cable length and diminish power usage. The connected device can substantially reduce the overall power consumption, which makes a significant contribution to energy saving.
