Operation
The HP 28684B EtherTwist Hub/12, HP 28688B Hub Plus, and HP 28699A Hub Plus/48
are designed to operate unattended. A console interface is provided with these hubs if you
wish to customize their configuration, monitor their activity, or run diagnostics. (For the
HP 28688B and HP 28699A, you can also perform these and other functions with the HP
network management products from a network management station anywhere on the
network. See your HP network management product documentation for more
information.)
