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).
