Railway Certified Switches

RailwayUnmanaged Railway Approval PoE+ Switch, 8x10/100/1000 PoE+ & 2xFX/GbE SFP


Realizing the essentiality in ease of use for 24/7 surveillance for today’s society, Volktek develops SEN-9428P-24V-RW Unmanaged Railway Certified PoE+ switch. The SEN-9428P-24V-RW is engineered with hardened components and enclosed in a case which can operate in wide temperature from  -40°C to 75°C, and playful even in harsh environments providing reliable surveillance.

The switch is compiled with intelligent PoE+ (IEEE 802.3af/at) function on 8-Gigabit copper ports and allows to supply up to 30W per port power budget over the single Ethernet cable to satisfy Powered Devices such as Wireless AP, VoIP phones and IP cameras eliminating the need of external power outlets. The 2-slot 100FX/Gigabit SFP give the advantages of configuring ring topologies for a safe, reliable and long distance Gigabit connectivity. Designed with sufficient beneficial features, SEN-9428P-24V-RW can be considered as a reliable option for harsh outdoor surveillance.

Robust Switch Performance
With a hardened metal case, surge and ESD protection, the SEN-9428P-24V-RW provides a high level of immunity against electromagnetic interference and heavy electrical surges, thus facilitating easy deployment in demanding environments. In addition, the SEN-9428P-24V-RW offers high-performance switch architecture with eight 10/100/1000BASE-T ports and two 100FX/Gigabit Ethernet SFP slots to meet the requirements of high-bandwidth access in wide operating temperatures.

High-Power Budget for PoE Network Devices
To fulfill the growing demand for high-bandwidth, high-power PoE for network applications and eliminating the cost of electrical cabling and circuits, the SEN-9428P-24V-RW is designed under IEEE 802.3at standard PoE+. With 240W PoE power budget capability for the whole system, the switch allows simple “plug-n-play” PoE for various types of high power consuming PoE devices. This makes the SEN-9428P-24V-RW a very convenient solution for applications far away from power outlets satisfying PoE extension applications in much longer distances.

Intelligent PoE Alive Checking
The SEN-9428P-24V-RW is designed with intelligent PoE+ features to utilize power more efficient. To monitor the real-time status of PDs, the switch sends alive-checking packets to PDs. If a PD fails to respond, the switch’s PD live check feature detects the failure and reactivates the PD. This reduces management burden and increases system reliability.

Redundant Power Input
Considering the power failure impact in surveillance applications, SEN-9428P-24V-RW is developed with standard “6-pin Terminal Block” for redundant power to provide continuous service resulting reliable and consistent network. In addition, the switch is equipped with an alarm feature to notify the occurrence of power failure, helps in quick respond and faster troubleshooting.

Future-proof Fiber Connectivity with Dual 100FX/Gigabit SFP Slots
With two multi-rate SFP slots, the SEN-9428P-24V-RW easily establishes fiber channel for Gigabit Ethernet connectivity and allows to take advantage of fiber-based daisy chain topology. The switch provides long distance, high-speed fiber connectivity while offering enhanced noise immunity and data security across deployed systems. The SEN-9428P-24V-RW is a well-suited robust, cost-effective and future-proof solution for fiber-based surveillance networks.
