Port extension

A redundantly designed Net Unit can be enhanced with a port extension.

In this case two redundant switches supplement the existing ports of the Net Unit to provide up to 96 redundant LAN ports.

The switches ICX6450-24 and -48 of the "base" Net Unit are connected to those of the port extension with an FC cable.

In the case of multi-rack systems, the switches can be integrated into different racks.

On the SE300 the port extension is possible if the Net Unit is redundant in design.
