HP 100Base-T Hubs 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.
• If you are inserting a Hub-24TX into a stack of Hub-
12TX/Hub-12TXMs that has been running an existing
firmware revision, make sure to download the latest version
of firmware so that your devices will be compatible and can
connect with one another with no problems. See the section
on the Xmodem Download VT-100 Interface console screen
in chapter 4 for more information about firmware
downloads.
• 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.
