Industrial PoE Switch

The PLANET ISW-514PTF is an industrial Ethernet switch with four 10/100Base-TX RJ-45 ports that supply IEEE 802.3af Power over Ethernet and one 100Base-FX SFP fiber interface. It is built for integrators deploying IP cameras or wireless access points in harsh environments. The IP30-rated metal case operates from -40 to 75 degrees Celsius. Redundant 24 or 48 V DC inputs with polarity reverse protection keep the link alive if one feed fails.

Sustained Load Behaviour

Store-and-forward switching checks every frame before forwarding, preventing corrupted packets from circulating under continuous traffic. The 2K MAC address table handles the device counts typical of small surveillance or automation segments without flooding. Each PoE port delivers up to 15.4 watts continuously, and the total power budget stays within the redundant supply limits. Full-duplex flow control pauses traffic instead of dropping frames when buffers fill during prolonged bursts.

Fibre Uplink Constraint

The single 100Base-FX SFP slot accepts multimode transceivers for reaches up to 2 kilometres, so the switch suits sites where copper cannot span the distance. Buyers needing longer single-mode reach, additional fibre ports, or Gigabit uplink speed must select a different model.

Questions about this item

How much heat does the ISW-514PTF generate when running continuously in a sealed cabinet?

The switch operates without a fan from -40 to 75 °C, so it produces only the low heat typical of a 15.4 W per port PoE budget.

What power source must I already have to run this switch?

You need a 24 V or 48 V DC supply; the unit accepts dual redundant inputs with reverse-polarity protection.

Will the 100Base-FX uplink work with my existing multi-mode fibre patch cords?

Yes, the SFP slot takes a 100Base-FX multi-mode transceiver with an SC connector for links up to 2 km.
