Making Expansion Connections
1 Facing the rear of frame, locate the two 28-pin expansion connectors on an expansion out-
put backplane.
The two expansion connectors on each backplane are labeled EXP INPUT and EXP OUTPUT.
Figure 6-7 shows the 3 types of backplanes:

2 Using a 4-meter WC0121 cable, connect the expansion input of the card in frame 1 to the
expansion output of the card in the same slot of frame 2.
Then using another 4-meter WC0121 cable, connect the expansion output of the card in
frame 1 to the expansion input of the card in the same slot of frame 2:.

Make sure that the connectors are oriented properly. Otherwise, you can damage the con-
nector pins.
In the upper bays of the router frame, the black side of the cable connector faces right and
the silver side faces left.
In the lower bays, the black side of the connector faces left and the silver side faces right.
Keep in mind that the cards in the lower bays are installed “upside down,” that is, rotated
180° with respect to the cards in the upper bays.
3 Repeat step 2 until all expansion connectors have been connected.
