Installing the Ferrite Bead on Ribbon Connectors
If the ferrite bead is closed, place the bead on a flat surface.
a. Insert a small flat-blade screwdriver into the recessed area under each of the two locking tabs.
b. Carefully pry outward to unlock the mechanism.
Step 2 Place the first open ferrite bead on the cable 8 inches from the end of the ribbon connector that is to be
attached to the RBBN-16-T1E1 back card (see Figure 5-86).
Snap the ferrite bead closed by pressing each half together until the two locking mechanisms snap firmly
shut.
Step 3 Place the second open ferrite bead on the same cable 60 inches from the end of the ribbon connector that
is to be attached to the RBBN-16-T1E1 back card.
Snap the ferrite bead closed by pressing each half together until the two locking mechanisms snap firmly
shut.
Step 4 To secure the beads, fasten one wire zip tie around the cable on each side of each bead.
Ensure that the ties are up against each side of the bead.
Step 5 (Optional) Repeat Step 1 through Step 4 for the other cable that connects to the RBBN-16-T1E1 back
card.
