Cables and Connectors

Figure 4-5 Optional Y-Cable Connections

The optional Y-cables can be used to provide one-to-one line card redundancy. For Y-cable redundant

applications, see the “Configuration Summary” section on page 4-9, and configure the hardware as follows:

• Two 4-port channelized T3 half-height line cards must share the same slot.

• Eight Y-cables are required to configure a redundant pair of 4-port channelized T3 half-height line

cards.

• The Y-cable has three BNC connectors. The two similar connectors must be connected to BNC

connectors on the Cisco 10000 series router backplane corresponding to similar functions on each line

card (for example, RX to RX), with the remaining connector being connected to the cable from the

customer’s network. See Figure 4-5. The following text explains how the Y-cable connects two 4-port

channelized T3 half-height line cards. Additional Y-cables can be used as required.

–

The Y-cable connects the 4-port channelized T3 half-height line card in subslot 0, port 0 RX to

the 4-port channelized T3 half-height line card in subslot 1, port 0 RX.

–

Another Y-cable would connect to the 4-port channelized T3 half-height line card in subslot 0,

port 0 TX to the 4-port channelized T3 half-height line card in subslot 1, port 0 TX.

–

The remaining six Y-cables are connected in a similar fashion to form a completely redundant

configuration.
