Product Overview
The Cisco ONS 15530 is a highly modular and scalable optical switching and aggregation platform.
With the CiscoONS 15530, users ca n take advantage of the availability of dark fiber to build a common
infrastructure that supports data, SAN (storage area network), a nd TD M ( t ime- division m ultip lexing)
traffic. For more information about DWDM technology and applications, r efer to t he Introduction to
DWDM Technology publication and the Cisco ONS 15530 Planning and Design Guide.
The Cisco ONS 15530 is designed to meet and exceed the most stringent ISP (Internet service provider)
requirements for product availability and reliability. Its features include:
•Redundant fan assemblies
•Redundant power (AC or DC)
•Redundant CPU switch modules
•Interfaces which can be configured for redundancy using SONET 1+1 APS ( Au toma ti c Prote c tion
Switching)
•Line cards, power supplies, and fan assemblies that are hot-swappable without powering down the
shelf

Chassis Overview

The Cisco ONS 15530 is available in two configurations. Both have two vertically stacked half-height slots
specifically for the OADM (optical add/drop multiplexers) modules, and 10vertically oriented slots which
hold the CPU switch modules, line cards, and transponder line cards. As you face the c hassis, the left most
slot (slot 0) holds two half height OADM modules. Slots 1through 4 and slots 7through 10 hold the line
cards and transponder line cards. Slots5 and 6 hold the CPU switch modules (see Figure 1-2). Power
supplies are located on the right side of the chassis next to slot10. Air inlet and fan tray are located beneath
the slots. Cable management is located above and beneath the slots. The system has an electrical backplane
