The RJ-45 connector is used to connect a Category 3, Category 5, Category 5e, or
Category 6 FTP or UTP cable from the external network to the module interface
connector. (See

Figure B-4
shows a schematic of the 1000BASE-T crossover cable.
Category 5e and Category 6 cables can store high levels of static electricity
because of the dielectric properties of the materials used in their construction.
Always ground the cables (especially in new cable runs) to a suitable and safe
earth ground before connecting them to the module.
To comply with GR-1089 intrabuilding, lightning-immunity requirements, you
must use foil-twisted pair (FTP) cable that is properly grounded at both ends.
