I am looking to use the GigaBlox Nano in a product we manufacture. I see in the description there is a reference to not exceeding a 1 Meter cable length. Our application would have on channel with a 3 Meter will this work? Are there work arounds?

Most likely 3 meters will also work too, but it’s something you’ll need to test first. The 1 meter we state is a bit of a rule of thumb. What’s more important is to ensure:

1. No major ground differences between GigaBlox Nano and the connected device (there is no galvanic isolation on GigaBlox Nano)
2. Consideration to externally induced noise into the data wires (you may need to shield the cables)

Feel free to share a bit more about what you’re connecting to and I can give better advice

Thank you very much for your quick response. The information helps a lot. We will do some testing. Can you answer one more question? It is product related; do you have any devices that can handle DHCP management on a small network of devices? Again, thanks for your help.

Moved that questions here

> DHCP is router level stuff (layer 3). At present all the hardware we sell is switch level (layer 2). We do have a product that will be able to do routing, this is [SwitchBlox Rugged](https://botblox.io/products/rugged-ethernet-switch) + [Rugged SoM](https://botblox.io/rugged-som/). But it’s not released yet. One workaround way of doing this is using a “router-on-a-stick” configuration. [Router on a stick - Wikipedia](https://en.wikipedia.org/wiki/Router_on_a_stick) For that you only need a switch that can handle VLANs; which [UbiSwitch](https://botblox.io/ubiswitch-module-3-x-10gbase-t-8-1gbase-t-switch/) and [SwitchBlox Industrial](https://botblox.io/switchblox-industrial/) can.
