Cisco ONS 15530 Overview
The Cisco ONS 15530 is a modular and scalable optical switching and
aggregation platform designed to supplement the Cisco ONS 15540 ESP. With the
Cisco ONS 15530, users can take advantage of the availability of dark fiber to
build a common infrastructure that supports data, SAN (storage area network),
and TDM (time-division multiplexing) traffic. For more information about
DWDM technology and applications, refer to the Introduction to DWDM
Technology publication and the Cisco ONS 15530 Planning and Design Guide.
The Cisco ONS 15530 is designed to meet or exceed stringent ISP (Internet
service provider) requirements for product availability and reliability.
Note Before you install, operate, or service the system, read the Regulatory
Compliance and Safety Information for the Cisco ONS 15500 Series for important
safety information you should know before working with the system.

Cisco ONS 15530 Chassis
The Cisco ONS 15530 is available in two configurations. Both have two vertically
stacked half-height slots specifically for the optical OADM (optical add drop
multiplexing) modules, and 10 vertically oriented slots that hold the CPU switch

modules, line cards, and 2.5-G transponder trunk line cards. Slot 0 holds two half
height optical OADM modules. Slots 1 through 4 and slots 7 through 10 hold the
line cards and transponder cards. Slots 5 and 6 hold the CPU switch modules.
Power supplies are located on the right side of the chassis next to slot 10. Air inlet
and fan tray assembly are located beneath the slots. Cable management is located
beneath the slots. The system has an electrical backplane for system control. All
optical connections are located on the front of the cards. Figure 1-1 shows a fully
populated chassis.

The chassis configurations differ in how cooling air is routed through the chassis
and where the lifting handles are placed.

The dimensions of the Cisco ONS 15530 CHAS-E chassis are 14.4 x 17.3 x 10.1
inches (H x W x D) See Figure 1-2. Handles for lifting the chassis are located on
the sides.

The fan assembly draws in cooling air through the air ramp baffle (see Figure 1-3)
on the bottom of the chassis, pushing the air across the internal components and
out the exhaust baffles on the top of the chassis.

Fan Assembly
The Cisco ONS 15530 fan assembly is located at the bottom of the chassis. The
assembly contains six individual fans and a fan controller board (see Figure 1-8).
The controller board monitors the status of each fan and reports the status to the
CPU switch modules. If a single fan fails, a minor alarm is reported to the CPU
and the fan assembly LED changes from green to yellow (see Figure 1-7). If two
or more fans fail, a major alarm is reported to the CPU and the fan LED changes
to red.
Table 1-1 lists the fan assembly LED status describing the alarm reports for the
fan assembly. The fan assembly is hot-swappable.

The Cisco ONS 15530 chassis supports redundant 120–240 VAC (see Figure 1-9)
or –48 VDC (see Figure 1-10) power. The power supplies are located at the right
of the chassis, next to the card slots (see Figure 1-1). Up to two power supplies
can be installed for redundancy.
