System Overview
The Cisco ONS 15530 is an optical transport platform that employs DWDM (dense wavelength division
multiplexing) technology. With the Cisco ONS 15530, users can take advantage of the availability of
dark fiber to build a common infrastructure that supports data networking and storage networking.

Chassis Description
The Cisco ONS 15530 uses an 11-slot modular vertical chassis (see Figure 1-1). As you face the chassis,
the leftmost slot (slot 0) holds up to two OADM (optical add/drop multiplexer/demultiplexer) modules.
Slots 1 to 4 and 7 to 10 hold the line cards. Slots 5 and 6 hold the CPU switch modules. Air inlet, fan
tray, and cable management are located beneath the modular slots. The system has an electrical
backplane for system control and signal cross connection via the switch fabric.
The system receives power from two +12 volt redundant power supplies. Both 120V AC and –48V DC
power supply options are supported.
