Connecting Other Hubs
You can connect the hub to another HP EtherTwist twisted-pair hub using any of the
network ports. Some examples are shown below. Note that twisted-pair cabling may pass
through intermediate cross-connect blocks. See the HP EtherTwist Technical Reference
Guide (part number 5091-3237E) for information on network topologies.
