The Switch Port Modules are not hot-swappable. Be sure you power
off the hub before installing or removing these modules.
Installing a Switch Port Module
- If you need to install a Switch
Port Module, take the following steps:
1. Disconnect power to the hub.
Retain the face plate for
possible future use.
2. Remove the face plate on the Expansion Slot (or a
previously installed Switch Port Module) by removing the
two screws with a Phillips (i.e., cross-head) screwdriver.
3. Before opening the package that contains the module, touch
the bag to the hub casing to discharge any potential static
electricity.
4. Remove the module from the anti-static shielded bag.
5. Holding the module level, gently insert the module, ensuring
that it engages the guides. Then insert it all the way.
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 the corresponding media type between the Switch Port
Module and the target device.
Avoid running your cables near
equipment that may generate
electromagnetic interference.
Connecting Twisted-pair Cabling - For the 10/100Base-TX
module, 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 Switch
Port Module to the target device. However, when connecting
the module to a hub or switch, connect one end of the cable to
the MDI port on the module, and the other end to an MDI-X port
