Attaching Ferrite Beads on the Cables

Ferrite beads can be clamped on where the beads are attached without wrapping the wires. Two ferrite
beads (part number 36-0219-01) are included in the Cisco uBR10012 router accessory kit, and one ferrite
bead is shipped with the spare of AC and DC power entry modules.
Attaching Ferrite Beads on Grounding and Alarm Cables
For Class B emission compliance requirements, one ferrite bead must be installed on the alarm port and
chassis ground wire exiting the chassis. This is applicable for UBR10-PWR-AC,
UBR10-PWR-AC-PLUS=, and UBR10-PWR-DC-PLUS= PEM modules. The ferrite bead should be
installed (within 3 inches) close to the notch where the cables exit the chassis.

If you are wiring the router in parallel with other equipment for the alarm indicators, connect the
other lead to the normally open (NO) terminal.

Step 3 for the remaining alarm indicators
Feed a tie wrap through the square slot on the front, to the left side of the chassis (next to the alarm
indicator terminal block).
Bind the wires to the chassis using the tie wrap.
