Reactivating the Primary Link
When the primary link is repaired, you can use any of the following methods to reenable the
primary port:
From the hub’s console, use the Port command, PO n ON where n i s the primary
port’s ID.
Cycle power on the hub. This is useful if you do not have access to the hub’s console
interface, for example, because the hub is in a wiring closet and a console is not
connected.
From an HP network management station, reenable the port or reset the hub. See the
network management product documentation for details on how to enable a port or reset
the hub.
When the primary port is reenabled, the backup port is automatically disabled and returned to
backup mode.
