Port extension

On SE700, SE500 and SE300 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 ICX 6450-24 and -48 resp. ICX 7450-48 of the "base" Net Unit are connected to those of the port extension with an FC cable.

In multi-rack systems, the switches can be installed in different racks. On the SE300 the port extension is possible if the Net Unit is redundant in design.
