Installing a SmartExtender Module - If you need to install an

extender module, take the following steps:

1.Disconnect power to the hub.

2.Remove the face plate on the expansion slot (or a previously installed SmartExtender Module) by removing the two screws with a Phillips (i.e., cross-head) screwdriver.

4.Remove the module from the anti-static shielded bag.

5.Holding the module level, gently push it all the way into the expansion slot, ensuring that it firmly engages with the connector.

6.If you are sure the module is properly mated with the connector, replace the retainer screws to secure the module in the expansion slot.

7.Run corresponding media type between the extender module

and the target device.

100BASE-T4 modules, prepare Category 5 straight-through twisted-pair cables with RJ-45 plugs at both ends. When connecting the module directly to an end-node device (e.g., a workstation or file server), a bridge or router, run cable from the MDI-X port on the SmartExtender Module to the target device. However, when connecting the module to a hub or switch,
