Chapter 3 Removing and Installing Line Cards

Connecting a SMB Cable

On a 6E3 line card, you can use six SMB cables (one for each E3 link).

Tip If you build your own cables, we strongly recommend that you fasten together your transmit and receive

cables along their entire length, as shown in Figure 3-2. Doing so reduces the effects of EMI. You can

use shielded jacketing or tubing for this purpose.

Caution Each E3 link requires separate receive and transmit connections to your external E3 equipment.

Caution When you connect the 10-foot (3.048 meters) shielded SMB cables to the 6E3 line card, be careful not

to bend the male cable connector pin when you connect or disconnect the cables.

Caution To prevent system problems and to maintain the proper cable connection sequences, connect the receive

and transmit ports on your 6E3 line card as indicated in Step 2.

To connect the SMB cables to the 6E3 line card, follow these steps:

Step 1 Attach the SMB cables directly to the SMB ports on the 6E3 line card. Attach the SMB ends of the cable

to the ports labeled TX and RX. (See Figure 3-2.)

Step 2 Attach the BNC ends of your SMB cables to your external E3 equipment as follows:

a. Attach the cable from the 6E3 line card TX port to the RX port on your external E3 equipment.

b. Attach the cable from the 6E3 line card RX port to the TX port on your external E3 equipment.
