  New slim type with more practicability and convenience PLANET has released the ISW-621/ISW-621S15, an advanced industrial hardened Ethernet Switch with new slim type, IP-30 metal case. Each of them is equipped with 4 10/100Base-TX auto-negotiation ports. The ISW-621 has 2 100Base-FX multi-mode SC interfaces for transmission distance up to 2km, and the ISW-621S15 has 2 100Base-FX single-mode SC interfaces for transmission distance up to 15km, both of them operate reliably in Heavy Industrial demanding environments. Meanwhile, the compact, IP-30 standard metal case allows either DIN rail or wall mounting for efficient use of cabinet space.   Stable operating performance under difficult environments The ISW-621 / ISW-621S15 provides 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. Being able to operate under the temperature range from -10 to 60 degrees C, the ISW-621/ISW-621S15 can be placed in almost any difficult environment. The ISW-621/ISW-621S15 also possesses an integrated power supply source with wide range of voltages (12 to 48V DC) for worldwide high availability applications requiring dual or backup power inputs.   Robust Switch performance The ISW-621/ISW-621S15 each provides 4 10/100Base-TX Ethernet ports and 2 100Base-FX optic-fiber SC interfaces, and boasts a high performance switch architecture that is capable of providing non-blocking switch fabric and wire-speed throughput as high as 1Gbps. With 2K MAC address table, they offer wire-speed packets transfer performance without risk of packet loss. The flow control function allows the ISW-621/ISW-621S15 to have fast and reliable data transfer.   All of the RJ-45 copper interfaces in the ISW-621/ISW-621S15 support 10/100Mbps auto negotiation for optimal speed detection through RJ-45 Category 3, 4 or 5 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.

The capital ‘T’ (ISW-621T and ISW-621TS15) shown in the model names means that they can support and operate under WIDE-TEMPERATURE environment ranging from -40 up to 75 degrees C. As we know the temperature in many places and countries of the world are lower than -10 degrees C, these two new models, ISW-621T and ISW-621TS15, will be the right products for Transportation, Manufacturing, Security and Surveillance network deployments in those harsh environments. The ISW-621T / ISW-621TS15 also provides 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.   Flexibly Extendable Distance They(the ISW-621T and ISW-621TS15) each include four 10/100Base-TX auto-negotiation ports and two 100Base-FX ports. The ISW-621T is equipped with 100Base-FX multi-mode SC interfaces for transmission distance up to 2km while the ISW-621TS15 is equipped with 100Base-FX single-mode SC interfaces for transmission distance up to 15km. The two 100Base-FX ports provide more flexibility for Transportation, Manufacturing, Security and Surveillance with distance extension without any limitation, making the ISW-621T / ISW-621TS15 suitable either for long distance (ISW-621TS15) or short distance (ISW-621T) network deployment.   Easy Installation and Wide Range of Power Usages The ISW-621T and ISW-621TS15 are designed with a compact case that allows either DIN rail or panel mounting for the efficient usage of cabinet space. It provides an integrated power supply with a wide range of voltages for worldwide operation. It also offers dual-redundant, reversible polarity 12V DC to 48V DC power supply inputs for high availability applications requiring dual or backup power inputs.
