Unpacking Procedures

When unpacking your 10BASE-FB Module:

1.Verify that the 10BASE-FB Module is the correct model by matching the model number listed on the side of the shipping carton to the model number you ordered (Model Numbers 5102M-FBP, 5104M-FBP, or 5104M-FB1).

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 module from the shipping carton.

3.Remove the module from the anti-static shielding bag and inspect it for damage. 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.

4.Keep the shipping carton and anti-static shielding bag in which your module was shipped for repackaging the module for storage or shipment.

5.Record the serial number of your 10BASE-FB Module. A log for this and other information specific to your modules is included in the ONline SystemConcentrator Installation and Operation Guide, Appendix B, Slot Usage Chart.
