Unpacking Procedures

Use the following procedure when unpacking your 10BASE-T Module.

1.Verify that the 10BASE-T Module is the correct model by matching the model number listed on the side of the shipping carton to the model number you ordered (5108M-TP).

Note that the product model number printed on the shipping box differs from the model number on the product. The model number on the shipping box contains the prefix ’3C9’.

2.Remove the 10BASE-T Module from the shipping carton.

3.Remove the module from the anti-static shielding bag and inspect it for damage. Always handle the 10BASE-T Module by the faceplate being careful not to touch the components.

If the module appears to be damaged, replace it in the anti-static shielding bag, return it to the shipping carton, and contact your local supplier.

3Com suggests you keep the shipping carton and anti-static shielding bag in which your module was shipped in case you later want to repackage the module for storage or shipment.

We also suggest that you record the serial number of your 10BASE-T Module. We have provided a log for this and other information specific to your modules under the Slot Usage Chart in Appendix B of the ONline System Concentrator Installation and Operation Guide.

Installation Procedures

You do not need to power down the ONline System Concentrator to install the 10BASE-T Module. You can insert the module while the concentrator is operating (called a hot insertion). Follow the steps below to install the 10BASE-T Module.
