10GbE Ethernet ports deliver high speed and huge bandwidth
Technology is rapidly advancing and the devices that are connected to the Ethernet are growing accordingly. Bandwidth needs are increasing. Autonomous vehicles integrate 8K panoramic cameras and various sensors to collect environmental information in order to move safely with little or no human control. The Ethernet switch needs to reliably handle data. If the Ethernet switch fails to perform adequately, latency and packet loss can happen, with the potential to impact transportation safety. With ITS applications starting to require faster & larger amounts of data, Ethernet switches with 10GbE uplinks should be the required choice for current and future expansion.
Two 10GbE uplink ports are not enough, choose one with four 10GbE ports
When planning for Ethernet switches for current and future requirements, consider a unit with a minimum of 4 X 10GbE uplink ports . Choosing a unit with 4 X 10GbE uplinks ports will allow for more expansion, flexibility & have future cost benefits. When choosing a DIN-Rail Ethernet switch for ITS applications, consider one with 4 X 10GbE ports.
PoE budget 30W per port is good, next-gen 802.3bt with 60W per port is great
Power over Ethernet (PoE) combines data transmission and power supply which helps reduce the cost of installation and maintenance. Normally, this is considered an essential requirement in ITS applications. However, only the switches that support IEEE802.3at/af/bt standard should be considered in order to guarantee the highest compatibility with end devices. 802.3at/af models can deliver up to 30Watts per port while 802.3bt models provide up to 60Watts per port. Choosing these models helps satisfy current needs and can also fulfill future requirements by upgrading to advanced devices with higher power consumption.
12/24VDC power booster – Best for vehicles, solar panel, and battery-related applications
12/24VDC power supply is commonly seen in vehicles, solar panel & battery applications, for example but, not every Ethernet switch can support it without an additional power supply. To support this power input range and provide PoE for devices at the same time, Ethernet switches with PoE boosters are the best solution. However, even though some products in the market have a built-in PoE booster, the total PoE budget under 12VDC operation is less than 80Watts. This can have limitations for ITS applications. Lantech Industrial PoE Ethernet switches include several models, which support various power inputs, ranging from 9.5-60Vdc and then 90Vac(120Vdc) – 305Vac(430Vdc).
Is it certified to meet your environment needs?
Different certifications apply to different kinds of environments. Adopting Ethernet switches with Internationally recognized certifications provides more protection for different environments, and enhanced reliability. E-Marking certification for vehicle applications and EN50155 certification for rolling stock applications are well-known and trusted certifications.
High specifications are future-proof and upgradable
To provide a stable and reliable performance under full-load or multi-tasking situations, Ethernet switches for ITS applications should be powerful enough and future-proof. High End specifications can provide higher throughput, & higher back-plane switching fabric, etc. Thanks to top specifications, Lantech OS3/OS4 managed industrial Ethernet switches have built-in Layer 2 plus management functions and are able to be upgraded to Layer 3 Lite or Layer 3 if needed in the future.
Monitoring switch’s status in real time assures a reliable network
Via the built-in environmental monitor, maintenance teams can check the system hardware status for the following parameters, temperature, input voltage, and power current. Maintenance teams can receive SNMP traps or email notifications when a configured parameter has been triggered. The enhanced monitor can show more detailed real time information, voltage input, CPU load, temperature & throughput in a graphical representation, making it easier to understand the switch status.
Wide range operating temperature stands for stability
Due to the wide range of applications covered by ITS, some of the applications may face all kinds of harsh environmental conditions. For example, an autonomous car may operate between the two extremes of temperature from Yakutsk in Russia; normally -34°C in the winter, to the temperatures in Kebili in Tunisia, normally + 40°C during summer months. If the Ethernet switch does not support a wide operating temperature, the networking system may become unstable or face interruptions. A true rugged switch for ITS should have a minimum operating temperature range of -40°C to +75°C (-40°F to +167°F).
Is it protected with galvanic isolation?
Lightning can strike anywhere on earth, the damage a lighting strike can cause due to the surge in voltage in an outdoor environment has always been a critical issue for customers. ITS applications are no exceptions, most ITS system have signs, cameras & sensors mounted high on metal poles. Lantech’s Industrial 10GbE switches provide galvanic isolation protection for the power input, reducing the risk of power currents flowing through the system directly, in turn this helps reduce the damage when the network runs into such harsh environmental disasters.
Support of PXE ensures the switch has the latest firmware
With PXE (Preboot eXecution Environment) supported, the Ethernet switches connected to a PXE server can keep updating to the latest firmware. It reduces the risk caused by running older firmware that may have vulnerability issues or security bugs.
