Have a safe and pleasant journey starting with PoE system

Overview

Rail is a pleasant mode of transportation, allowing travelers to conveniently and comfortably travel from one point to another. However, safety is the first priority for passengers at the railway station or platform, and that makes security monitoring a key task for rail administrators. The proper deployment of cameras can ensure passenger's safety, prevent unauthorized entrance to restricted areas, and to monitor if any belongings are accidentally left by passengers... more

The Challenges

Installation:
The system shall fit into a 19 inch 12U rackmount cabinet. Working under extreme temperatures, the system should operate at -20 to 70°C without a fan.
Bandwidth:
The network devices needed to have high bandwidth and non-blocking to deliver video data, 10G uplink support is preferable.
Management:
The system must support at least Lite Layer 3 functions and even be certified with EN 50121-4.
PoE level should be higher than IEEE 802.3at, and the total power budget should be more than 480 watts.

The Network Solution

EtherWAN's EX75900 PoE Lite Layer 3 managed switch was a perfect fit for the project. The EX75900 is a hardened full gigabit managed Ethernet switch in rack-mount form factor featuring 24 ports of 10/100/1000BASE-T(X) each in compliance with IEEE 802.3bt plus 4 ports of 1G/10G SFP+ for connecting to the core network. The high density port count of EX75900 can minimize the number of switches needed for installation in order to connect with the maximum number of cameras.

The EX75900 provides a total power budget of up to 720 watts, supporting linked surveillance cameras, pan-tilt-zoom (PTZ) cameras, speed domes, and even laser cameras. The intelligent PoE functions, including Scheduling, Watchdog and Force mode, allow for comprehensive smart management of powered devices.
