Cost-effective Full PoE+ Power Solution Ideal for Hardened Environment Featuring Plug and Play designed to be installed in heavy industrial  environments, the IGS-624HPT is a PLANET Industrial-grade, DIN-rail type Unmanaged Gigabit Ethernet PoE+ Switch with four 10/100/1000BASE-T ports featuring IEEE 802.3at PoE+ and two extra 100/1000/2500BASE-X SFP fiber optic interfaces for uplink connection. The IGS-624HPT, designed with redundant power system, is able to operate reliably, stably and quietly in any hardened environment without affecting its performance. It comes with a total power budget of up to 120 watts for different kinds of PoE applications and operating temperature ranging from -40 to 75 degrees C in a rugged IP40 metal housing.     Convenient and Reliable Power System To facilitate the 802.3at PoE+ usage with commonly used 12~54V DC power input for transportation and industrial-level applications, the IGS-624HPT adopts 12~54V DC to 54V power boost technology to solve power source issue but does not require special power supplies. The IGS-624HPT provides an integrated power solution with a wide range of voltages (12~54V DC) for worldwide operability. It also provides dual-redundant, reversible polarity 12~54V DC power supply inputs for high availability applications.     Adjustable 6-Port Switch Mode or 4 + 2 Fiber Redundant Mode Via the built-in DIP switch, the IGS-624HPT can be configured as 6-port Gigabit Ethernet switch or 4+2 fiber redundant mode. With the 6-port Gigabit Switch mode, the IGS-624HPT can operate in Store-and-Forward mechanism with high performance; on the other hand, when in the 4+2 fiber redundant mode, it provides rapid fiber redundancy of link for highly critical Ethernet applications. The redundant mode also supports auto-recovering function. If the destination port of a packet is link down, it will forward the packet to the other port of the backup pair.     Fiber Optic Link Capability for Flexible Distance Extension The additional two mini-GBIC slot built in the IGS-624HPT supports SFP auto-detection and dual speed as it features 100BASE-FX, 1000BASE-SX/LX and 2500BASE-X SFP (Small Form-factor Pluggable) fiber-optic modules, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and 10/20/40/60/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications to uplink to backbone switch and monitoring center in long distance.     Environmentally Hardened Design With the IP40 metal industrial case, the IGS-624HPT 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 without air conditioning. It features a ventilated construction in which a cooling fan is not necessary, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, the IGS-624HPT can be placed in almost any difficult environment.   Robust Protection The IGS-624HPT provides contact discharge of ±6KV DC and air discharge of ±8KV 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.   Intelligent LED Indicator for Real-time PoE Usage The IGS-624HPT helps users to monitor current status of PoE power usage easily and efficiently by its advanced LED indication. Called “PoE Power Usage”, the front panel of the Industrial Gigabit PoE+ Switch has four orange LEDs indicating 30W, 60W, 90W and 120W of PoE power usage.     Flexible and Easy Installation with Limited Space The compact-sized IGS-624HPT is specially designed to be installed in a narrow environment, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail, thereby making its usability more flexibly and easily in any space-limited location.
