Chapter 17 Installing and Removing Line Cards
Attaching Cables
• 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 17-40. 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.
Configuration Summary
Caution The Y-cables must be installed before configuring redundancy, and removed before deconfiguring
redundancy.
1. To configure redundancy, you must:
a. Attach all Y-cables in this order: to the primary line card, to the secondary line card, and to the
far end.
b. Configure the primary line card.
c. Configure the secondary line card.
2. To deconfigure redundancy:
a. Use “red line switch from...” to make the secondary line card standby (if it is active) and the
primary line card active if you want to deconfigure only the secondary line card (perhaps for
servicing).
b. Detach the Y-cable from all ports on the secondary line card.
c. Deconfigure the secondary line card.
3. If you want to deconfigure all redundancy, you must:
a. Remove all the Y-cables and the cable for nonredundancy if desired.
b. Deconfigure the secondary line card and primary line card.
See the Cisco 10000 Series Routers Line Card Configuration Guide for information about configuring
redundancy using the optional Y-cables.
