Cabling a Multi-Chassis Configuration
• The installation must follow national and local electrical codes: in the United States, National Fire
Cabling the Ethernet Control Plane Network
This section describes how to cable the control plane network for the Cisco NCS 6000 Multi-Chassis system.
These connections control the network connectivity for the multi-chassis system. The following cabling
configurations are described:
The control plane network carries all the signaling, routing updates, system configuration and management
packets for the NCS 6000. The control network must be cabled before the NCS 6000 system can become fully
operational.
The control plane of the multi-chassis system is connected between the LCC and FCC with four paths per
LCC (two per RP). The ports between the LCC and FCC are connected with SFP+ modules. Each RP on the
LCC has 10GE connections that connect to each of the two SC-SW cards in the FCCs. The SC-SW cards
provide the control plane network between all chassis.
Each SC-SW card has 56 10GE connections and two 40GE connections. Two SC-SW cards are used for
redundancy purposes. These cards interconnect to each other through their 40GE QSFP optical ports. Each
RP and each SC in a multi-chassis system connects to both switches. Note that an SC must be externally
connected to both SC-SW switch cards though a 10GE port even if the SC and SC-SW cards are installed in
the same FCC.
