A Perfect Full PoE+ Power Solution Ideal for Hardened Environment
With Plug and Play design, PLANET ISW-504PT Industrial-grade, DIN-rail type Unmanaged Fast Ethernet PoE+ Switch, featuring  4 IEEE 802.3at PoE+10/100BASE-TX ports and 1 additional Fast Ethernet RJ45 interface for uplink connection, allows to automatically detect and configure internal and external peripherals

The ISW-504PT is designed with redundant power system and 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 the commonly-used 12~54V DC power input for transportation and industrial-level applications, the ISW-504PT adopts 12~54V DC to 54V DC power boost technology to solve power source issue but does not require special power supplies. Its wide-ranging voltages design is suitable for worldwide operability with high availability applications requiring dual or backup power inputs.

802.3at PoE+ Power and Ethernet Data Transmission Extension
The ISW-504PT has a built-in solid DIP switch providing “Standard”, "VLAN" and “Extend” operation modes. By default, the ISW-504PT operates as a normal IEEE 802.3af/at PoE+ Switch in the “Standard” operation mode. 
The "VLAN" operation mode features with port-based VLAN function helps to prevent the IP camera’s multicast or broadcast storm from influencing each other.

In the “Extend” operation mode, the ISW-504PT operates on a per-port basis at 10Mbps full duplex operation and can support 25-watt PoE power output over a distance of up to 250 meters, overcoming the 100-meter limit on Ethernet UTP cable. 
Environmentally-hardened Design
With the IP40 metal industrial case, the ISW-504PT 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 ISW-504PT can be placed in almost any difficult environment.

Robust Protection
The ISW-504PT provides contact discharge of ±5KV DC and air discharge of ±5KV DC for Ethernet ESD protection. It also supports ±5KV 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 ISW-504PT helps users to monitor the 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 ISW-504PT is designed to be installed in different environments, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail mounting, thereby making its usability more flexible and easier in any space-limited location.
