Use the Ethernet-Mux in a clean working environment.
Don’t let the Ethernet-Mux get in contact with water or coffee.
To use the internal GPIO-based control interfaces some modifications, including disassembly and soldering, to the device are required. The person performing these modifications should be trained in performing these tasks. Modifications to the Ethernet-Mux performed in a non-ESD-protected environment may cause damage to the device.
While not actively tested in the development of the product, contact with other beverages than the ones listed above may also cause adverse effects.
