Switch no gestionado PLANET ISW-621TS15

The PLANET ISW-621TS15 is an unmanaged industrial Fast Ethernet switch with four 10/100Base-TX ports and two 100Base-FX fiber ports. This model supports wide operating temperatures from -40 to 75 °C and is built to resist electromagnetic interference and electrical surges common in transportation, manufacturing and roadside traffic cabinets. The ISW-621TS15 uses single-mode SC fiber for extended links up to 15 km, making it suitable for long-distance network extensions while remaining compliant with IEEE 802.3 standards.

Advantages

The ISW-621TS15 provides extended-temperature operation and robust protection against EMI and power surges, allowing reliable deployment in harsh environments. With two 100Base-FX fiber ports (single-mode, SC) it supports long-distance transmission up to 15 km. The compact metal housing supports DIN-rail or panel mounting and features wide-range DC power inputs with dual-redundant, reversible-polarity terminals for higher availability.

Suitable for

• Transportation networks (signalling, vehicle systems)
• Industrial/manufacturing plant networks
• Security and surveillance systems requiring long fiber links
• Roadside traffic control cabinets and outdoor enclosures

How to use

Mount the switch on a DIN rail or panel inside an appropriate enclosure, connect the DC power inputs with correct polarity or to both redundant supplies for higher availability, and link copper devices to the RJ-45 ports. Use single-mode SC fiber cables to connect remote fiber equipment to the 100Base-FX ports, observing standard fiber handling and termination procedures. The device is unmanaged and requires no configuration; it will forward traffic based on MAC learning.

Recommendations

Install the ISW-621TS15 in well-ventilated cabinets, verify fiber connectors and power polarity before powering up, and use redundant DC supplies where continuous operation is critical. For long-distance fiber runs, choose appropriate single-mode fiber and observe end-to-end optical budget requirements.
