Shelf Configuration Rules

The design of the Cisco ONS 15530 requires that a set of rules be followed during physical configuration

of the shelf. These rules, along with examples, are provided in this chapter. This chapter contains the

following major sections:

• Shelf Rules for OADM Modules, page 3-1

• Shelf Rules for PSMs, page 3-2

• Shelf Rules for 2.5-Gbps ITU Trunk Cards, page 3-2

• Shelf Rules for Transponder Line Cards, page 3-2

• Shelf Rules for 10-Gbps ITU Trunk Cards, page 3-3

• Shelf Rules for 10-Gbps ITU Tunable Trunk Cards, page 3-3

• Shelf Rules for 10-Gbps Uplink Cards, page 3-3

• Shelf Rules for OSC Modules, page 3-3

• General Rules for Ring Topologies, page 3-3

Note Applying the shelf configuration rules requires an understanding of the Cisco ONS 15530 system

components and protection schemes.

Shelf Rules for OADM Modules

This section describes the shelf rules for OADM (optical add/drop multiplexer) modules for different

types of protection.

Cabling OADM Modules

The following rules apply when cabling the trunk, thru, and OSC ports on the OADM modules:

• Use fiber optical cables with MU connectors to cable an OADM module to other OADM modules,

to OSC modules, to transponder line cards, 2.5-Gbps ITU trunk cards, and to 10-Gbps ITU trunk

cards.

• Connect the OSC IN on the OADM module to tx on the OSC module and connect the OSC OUT on

the OADM module to rx on the same OSC module. Perform the same process with the redundant

OADM module and OSC module.
