Configuring of Network Redundancy
Network redundancy must be provided by the network switches
connected to the 10-Channel Rack. These switches must support
the Rapid or standard Spanning Tree Protocol. This protocol
quickly reconfigures the network when a failure occurs, preventing
network loops which may otherwise occur if two switch ports on
the 10-Channel Rack are connected.
If Spanning Tree is not enabled on the network, network
redundancy cannot be provided to the 10-Channel Rack and only
one of the network ports should be connected to the network.
Caution
If your network does not support the Spanning Tree Protocol, connecting
your network to two ports may cause a network loop and excessive
network traffic.
IndigoVision recommends that two of the 10-Channel Rack switch
ports are connected to different network switches, ensuring that if
one switch fails, the other will maintain network connectivity
