Empirical Engineering Insights
Alternative Models & Compatibility
The T-suffix in the model designation indicates an extended temperature rating (-40 to 75 degC), making it a direct drop-in replacement for standard-temperature variants in harsh environments. It is fully backward compatible with standard 10/100 Mbps Fast Ethernet devices, automatically negotiating speed and duplex settings.
Application Pitfalls & Engineering Notes
Be mindful of the switch's high inrush current of 17.4 A at 24 V DC during startup (lasting up to 1 ms). Ensure upstream power supplies and circuit breakers are sized to handle this transient load without tripping or causing voltage sags that could affect adjacent control hardware.
Commissioning & Wiring Tips
To achieve true power redundancy, connect the two removable 2-pole terminal blocks to separate, independent industrial power supplies. Always ground the switch housing using the integrated grounding screw to minimize electromagnetic interference and protect internal circuitry from electrostatic discharge.
Installation Guidelines
CRITICAL WARNING
De-energize all power sources before connecting or disconnecting the terminal blocks. Do not hot-plug the power terminals or exceed the maximum rated input voltage, as this can cause permanent damage to the switch and connected PoE devices.
1
Snap the switch securely onto a standard TS 35 DIN rail, ensuring the top hook engages first before pressing the bottom of the unit until it clicks into place.
2
Connect a dedicated functional ground wire from the chassis grounding screw to the main panel ground busbar.
3
Wire the redundant DC power sources to the removable terminal blocks, ensuring correct polarity, and plug them firmly into the switch.
4
Insert the RJ45 network cables. The auto-MDI/MDI-X feature eliminates the need for crossover cables when connecting to other switches or end devices.
