Introducing the New Lite-Managed Series: Unlock Enhanced IEEE802.3bt PoE++ Injector Functionality!

OT Systems Ltd - Transmission and Mobile Surveillance Solutions Specialists
Value-added Lite-Managed IEEE802.3bt PoE++ injector function for a New Generation Network Deployment

OTS has launched the ET4222PpH-S-DR / ET4222Pp9H-S-DR, a hardened version ideal value-added Lite-Managed with 4-port 10/100/1000Base-TX Network Switch, it adopts IEEE802.3af/at/bt standard PoE++ injector technology, enable to deliver up to 95-watt per port power output as well as high-speed transmission for power devices which installed in a remote core network as required and reliable power input. The new generation is designed with an ideal option for edge connectivity in networking, comprising robust hardware performance and supports flexible DIP Switch with smart management software functions such as RSTP/VLAN/SFP SPEED.


Featuring industrial grade cases and Plug and Play designed to be installed in harsh industrial environments. Its two 1000-Base SFP ports fiber optic uplink provides long transmission distance from 550 meters to 20 kilometers (multi-mode fiber or single-mode fiber are depending on SFP module) in addition to speed required to extend the network efficiently.
Introducing the IEEE802.3bt PoE plus plus solutions as well as somewhat which built-in unique PoE management functions in.
the DIP SWITCH is able to easily control these features of RSTP, VLAN and SFP Speed, and it's also armed dual power input for high reliability
The series possess fault alarm function can trigger alert system when its malfunction take place. And its environmentally hardened design provide a complete protection.
