Multimodule Horizontal Cabling Plans


This appendix provides you with information about multimodule horizontal cabling plans for the following expanded Cisco CRS Multishelf installations:

8+1 Multimodule Installations—For eight LCCs and one FCC.

8+2 Multimodule Installations—For eight LCCs and two FCCs.

8+4 Multimodule Installations—For eight LCCs and four FCCs.

Cabling 8+1 Multimodule Installations

This section describes how to physically cable the fabric planes between each line card chassis (LCC) and fabric card chassis (FCC) in an 8+1, 8+2, or 8+4 Cisco CRS Multishelf installation using a horizontal multimodule cabling scheme.

Cabling the Control Network

For information about how to cable the control network for a single FCC, see the section, "Connections for a Single-FCC System" in Chapter 4.

S2 Fabric Card Distribution

Because there is only one FCC in an 8+1 installation, and multimodule installations support horizontal expansion, the FCC is fully loaded with 24, S2 fabric cards.

Rules for Multimodule Fabric Connectivity

The following rules and characteristics define the requirements for positioning S2 optical interface modules (OIMs) in the multishelf system and connecting them to the S13 cards in the LCCs.

Each plane is supported by a set of three S2 fabric cards for a total of 24 S2 fabric cards.

At the LCC end of a fabric cable, the plane number is determined by the slot to which the cable is connected. The other end of each fabric cable must connect to a set of three FCC S2 fabric cards designated for the same plane number. See Table A-1 for the entire fabric cabling plan for an 8+1, an 8+2, or an 8+4 Cisco CRS multishelf installation.

When connecting fabric cables from an LCC to a set of three FCC S2/OIM fabric cards in an 8+1 installation, connect LCC-Rack 0 cables to J0 on all three OIM cards for the same plane. Connect LCC-Rack 1 cables to J1 on all three OIM cards for the same plane.

Horizontal Cabling Cable Plan For Eight Line Card Chassis and One to Four Fabric Card Chassis

See Table A-1 below for the cabling plan for each line card chassis LCC 0 through LCC 7 and a single fabric card chassis (FCC 0), two fabric card chassis (FCC0 and FCC1), and four fabric card chassis (FCC0, FCC1, FCC2, and FCC3), each connected with horizontal cabling: In Table A-1 below, N equals 0 through 7, corresponding to LCC0 through LCC7
