Stacking Ports
The unit has two Stacking Ports labeled In and Out for combining
the hub with other compatible hubs to form a single hub stack
(up to a maximum of five hubs). The Stacking Cable that
comes with this package is used specifically for these ports.
Only hubs connected through the
In and Out Stacking Ports can
be managed by a network management agent (Hub-12TXM).
In
Using a Stacking Cable, connect this port to the Out port of any
Hub-12TX/Hub-12TXM.
Out
Using a Stacking Cable, connect this port to the In port of any
Hub-12TX/Hub-12TXM.

The unit also supports “hot swap” for the Stacking Cable. This allows
you to unplug the Stacking Cable while the unit is powered on.
However, if the Stacking Cable is disconnected at any point in the
stack, or is not properly terminated, all Ethernet and management
traffic passing through the cable will be disrupted.
