HP Hub-12TX/Hub-12TXM Installation and Reference Guide
Quick Installation vii
• Make sure you connect the stack (main collision domain) to
the extended network. If you have hubs in the stack that are
isolated, be certain to use a station port of a hub that is NOT
isolated in order to connect the stack collision domain to the
extended network.
• A network management station on the extended network
should be able to access a Hub-12TXM in the stack in order
to manage all the devices in the stack’s collision domain.
Make sure that the Hub-12TXM is NOT isolated, it should
be in the stack’s main collision domain and connected to the
extended network.
