March, 2004 Page 1 of 2 VANGUARD 6435 and 6455 HARDWARE ADVISORY NOTICE Introduction This Hardware Advisory Notice (HAN) applies to the Vanguard 6435 and 6455. A ferrite bead is included with every G.SHDSL daughtercard shipped. The ferrite bead installation is required only on the Vanguard 6435 and 6455. Installing a Ferrite Bead on a 6435 and 6455 This notice explains how to install a ferrite bead, which filters out line disturbances, on audio and power cables. Installation of a bead is required to ensure compliance with the European Union (EU) EMC Directive 89/336/EEC and compliance with FCC Part 15, Class A. Failure to install the ferrite component will result in non-compliance with the EU EMC Directive and may cause interference with other electrical equipment. Note The bead is required on the Vanguard 6435 and 6455. Before installing a ferrite bead on an audio cable, be sure you have the audio cable that shipped with your G.SHDSL Daughtercard. Example Installation Figure 1 on the following page shows how to install the ferrite bead on the cable. Step Action 1 Snugly wrap the cable twice completely around the bead (see Figure 1). 2 Set the cable into the bead cutouts. 3 Ensure 1 to 1-1/2 inches (25 to 38mm) of the cable protrudes from the bead (on the end you insert into the G.SHDSL Daughtercard’s rear panel connector). 4 Snap the bead closed. You can re-open and close it to re-set the cable. 5 Insert the cable into the appropriate connector on the rear of the G.SHDSL Daughtercard (with the ferrite bead closest to the Daughtercard’s rear panel connector).
