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.

Cisco ONS 15530-CHAS-E Chassis

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.

The air ramp baffle for the Cisco ONS 15530 CHAS-E chassis redirects the

cooling air intake as shown in Figure 1-4. The air ramp baffle must be installed

when installing the Cisco ONS 15530 CHAS-E type chassis.

The dimensions of the Cisco ONS 15530 CHAS-N chassis are 14.4 x 15.7 x 10.1

inches (HxWxD).(See Figure 1-5.) Handles for lifting the chassis are located

on the top. The fan assembly draws in cooling air through the intake baffles on the

front of the chassis, below the fan assembly, pushing the air over the internal

components and out the exhaust on the top rear and sides of the chassis (see

Figure 1-6).

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.
