Network Hubs

The Network Hub module makes up the backbone or Main Bus of the network. Multiple Network Hubs can be configured to increase the size of the network or to increase the number of available ports in an installation location. Up to 50

etwork Hubs can be connected on a single

N network with a patch cable length of up to 2000 feet. Refer to the ConviaNet Design Guide for more information.

Step 1: Mount Network Hub securely using

Mounting Holes

Step 2: Connect Power to Network Hub.

NOTE: To ensure proper network functioning, Communication

Loop Closures need to be installed into the beginning and end of the Main Bus of the network. If there is only one Network Hub in the installation, then Communication Loop Closures must be installed in both RJ11 ports on the Network Hub.
