Stacking Two Hubs - Planet NOVA100 Series Manual

1. Select a port on the hub
2. Plug one end of the cable into the node's RJ-45 port.
3. Plug the cable's other end into the selected RJ-45 port on
the hub.
To test an end-node connection, connect the hub to power,
then turn the hub and the end node on. The link indicator for
the port should shine steadily. If it does not, check the cable
and all connections.

Stacking two Hubs

Two hubs –FN-500 or FN-800 can be connected by using the
attached expansion cable -- DB25 to DB25 cable. Please refer
to the following steps for stacking.
1. Set a ID of the hub which is going to be stack. Make sure
using different ID number of each hub.
2. Connect one end to any port of expansion connectors of
hub.
3. Connect the other end to any expansion port of another hub.
These two hubs are stacked together.
4. By repeating the same method, totally 5 hubs maximum.
can be stacked to form a big "Stack".
Please be noted that,
a) Use of other DB25-to-DB25 cable while stacking will
affect the performance and cause emission problem.
b) Power on or Power off the "Stack" at the same time.
This kind of expansion won't sacrifice any station port, but all
the staked hubs would locate at the same place.
