Step 4

Insert the connector until it clicks and locks into place.

Step 5 Attach the other end of the cable to another node. The TX port on the line card must be connected to the

RX port on the next node, and the RX port on the line card must be connected to the TX port on the next

node. The labels next to the fiber connectors identify TX and RX.

Note The fiber-optic connectors must be free of dust, oil, or other contaminants. Carefully clean the fiber-

optic connectors using an alcohol wipe or other suitable cleanser.

T3 Cables

Cisco recommends using RG-179 T3 cables to connect line cards with T3 connectors. The cables are

10 feet long (3.048 meters) and have a female SMB connector on one end, and a female or male bayonet

coupling (BNC) connector on the other end. Use the female BNC cable connectors to connect the local

line card RX and TX ports. Use the male BNC cable connectors to connect the line card RX and TX ports

to other devices. See Figure 18.

Note Cisco does not automatically provide the RG-179 T3 cables recommended for your line cards.

Note Electromagnetic compliance (EMC) was verified with the 10-foot (3.048-meter) cables that Cisco

supplies. Cisco recommends that you use only the 10-foot (3.048-meter) T3 cables that are supplied with

the 6CT3-SMB line card; otherwise, EMC compliance is not guaranteed.
