CHAPTER
Cisco ONS 15530 Overview
The Cisco ONS 15530 is a modular and scalable optical switching and
aggregationplatform designed to supplement the Cisco ONS 15540 ESP. Withthe
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 availablein 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 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.

Power Supplies
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.

Backplane
The Cisco ONS 15530 backplane implements all board-to-board signal
interconnects and provides power distribution within the chassis. Connections are
present for two power supplies and the fan assembly. The backplane contains a
total of 12 slots; two half-height slots for the OADM modules, two full height
slots for the CPU switch modules, and eight full height slots for line cards and
transponder cards.
Cable Storage Drawer
The cable storage drawer is mounted directly below the fan assembly. It provides
storage for the excess cable length. Sliding radius limiters move to release the
excess fiber cable slack when the drawer is pulled out, allowing the user to raise
the fiber routing tray and access the fan assembly.

CPU Switch Modules
The Cisco ONS 15530 supports two CPU switch modules for redundancy, one in
activemode and the other in hot-standby mode. CPU switch modules are installed
in slot 5 and slot 6. Each CPU switch module has a processor, a switch fabric, a
clock, an Ethernet switch for communication between processors and with the
LRC (line card redundancy controller) on the OADM modules and line cards, and
an SRC (switch card redundancy controller). The active processor controls the
system. All LRCs in the system use the system clock and synchronization signals
from the activeprocessor.Interfaceson the CPU switch modules permit access by
10/100 Ethernet, console terminal, or modem connections.
Figure 1-11 shows the front panel of the CPU switch module.
