You can define color and usage (description) for your cables to easier trace and visualize the routes of your network connections. You must have user rights to configure network cables (Genome Library and Network Cable Types in System Setup>User Rights and Authentication).

If you have upgraded from a version prior to 7.4, all your existing connections will be gray and must be configured as well. 

1. Go to Tools>Configure Network Cable Types.
2. Click Add and define a color and a description for your cable.
   These do not depend on the physical cable type in hand but if you want your graphical overview to resemble what you see in your data center, define your cables to resemble their physical appearance.

Note: You must configure each existing cable individually as there is no link between the cable and the Configure Network Cable Types dialog box once the cable has been defined, saved and added to the room layout. So if you define color and usage for a fiber cable, this configuration will not affect the color and description of any fiber cables already in the room layout.
