Carrier Access 1750 Manual De Usuario

For FCC Part 15 Class A compliance for EMI/RFI suppression, the Broadmore 1750 
requires that a ferrite bead (P/N 010-0051) must be attached to each DC power cable, 
Ethernet cable, and alarm cable. FCC compliance also requires that an EMI cable be 
attached between the chassis and air deflector. Accessory kits are included with the 
Broadmore chassis. Use the following guidelines for FCC compliance.

DC power, one or two cables. Attach one ferrite bead to each cable, using a single 
wrap so that the cable passes through the bead twice (see figure below left).

Ethernet, one or two cables. Attach one ferrite bead to each cable, using a single 
wrap so that the cable passes through the bead twice.

Alarm cable. Attach one ferrite bead to the cable, using a single wrap so that the 
cable passes through the bead twice.

EMI cable. The EMI cable must be attached vertically across the bottom rear 
opening (see figure below right). Remove the existing screw at the top center of 
the air deflector at the rear of the unit. Discard the existing flat washer. Using the 
existing screw, attach the ring terminal of the EMI cable to the air deflector. 
Attach the ground clip to the other end of the EMI cable. Attach the ground clip 
with the EMI cable to the top center of the rear cable tray support channel.
