SEN-9648P-24V-RW is a managed railway certified PoE+ switch. It has eight 10/100/1000Base-T ports and 4 Gigabit SFP slots. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C.

Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.
High-Power Budget for PoE Devices
IEEE 802.3at standard PoE+ with 240W total power budget for the whole system and various plug-n-play PoE devices.
Intelligent PoE+ Functions
Allocation of power to various ports on 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.
