J7 CableConnectionUse a standard 8-position RJ45 connector and data cable to connect to J7. Add a ferrite block to reduce radiated emission. The one inch square ferrite block with built-in housing clip is packaged and shipped with the power supply interface card. To install the ferrite block:1. Position the block no more than 5 cm (2 in.) from the power supply end of the J7 user cable.2. Open the ferrite block housing.3. Loop the cable through the ferrite block. See Figure2.7, “J7 User Cable with Ferrite Block” on page 33.4. Close the housing clip.The ferrite block ensures that the power supply system meets radiated emission requirement 89/336/EEC for CE mark approval. See the power supply's operating manual for noise specifications.
