SEN-9648P-24V-RW is an 8-port 10/100/1000 PoE+ downlink and 4-port GbE SFP uplink managed industrial-grade switch designed to meet the thermal requirements and environmental conditions of surveillance and WAP Railway applications. This PoE+ switch features up to 8-port PSE (power sourcing equipment) ports with plug and play feature to provide power to all the powered devices (PDs) as soon as they are connected. The fiber ports allow noise-free Gigabit Ethernet transmission for fast recovery, reliable and long-distance to other switches and the control center.

The RJ45 type console port allows outbound network troubleshooting when networks go wrong. The USB port, designed to save configuration files, save system log files, and upgrade firmware, reduces network downtime and operational costs. The switch offers various in-built traffic optimization and network performance features to prioritize industrial applications, prevent the loss of data during communication, and assure a stable transmission. The switch includes a topology map compatible with third-party devices to monitor the network. This device complies with cybersecurity standards to safeguard the network from vulnerabilities and protect your assets.

This switch is built with industrial-grade components, enclosed in an IP30 aluminum case with high thermal conductivity to protect the device from tools and hazards. The wide input power range from 24V to 57V enables the device to operate in many railway applications without extra power outlet installation needed. To ensure reliability the redundant power supply and alarm relay contact on the terminal block ensures non-stop operations and issues alerts if power fails. Designed to withstand vibration, shock, free fall, and temperatures ranging from -40℃~75℃ (-40°F~167°F) it suits places like tunnels.


High-Power Budget for PoE Devices
Compliant with PoE+ (IEEE 802.3at), the switch supplies 30W per each PoE port, for a 240W total power budget and allows simple “plug and play” PoE for various types of high power-consuming PoE devices.

Intelligent PoE+ Functions
Allocation of power to various ports on an hourly or weekly schedule to enable or disable connected devices.

Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-240P-48 and SDR-240-24.

Efficient Network Monitoring and Management
SNMP (Simple Network Management Protocol) and RMON (Remote Monitoring) for efficient traffic management and monitoring. 

Bandwidth Management to Prevent Network Malfunction
QoS (Quality of Service) mechanisms for priority assignment and network traffic control.

Redundant Ring for Fast Network Recovery
Xpress Ring for detection and recovery of failed network in milliseconds.

Resistant to Extreme Environments
The device is built with Industrial grade components, tested in-house, and certified for reliable operation in harsh environmental conditions by international market safety organizations like CE, FCC, and ROHS. Strong tolerance to extreme temperatures (-40°C~75°C), and resistance to interference makes this device infallible in demanding industrial environments around multiple types of machinery. Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over-voltage, over current, and reverse polarity.
