Chapter 2 Quick Installation Procedures

Common Installation Procedures

Caution Use extreme care when removing or installing connectors so you do not damage the connector housing or scratch the end-face surface of the fiber. Always install filler modules on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

Use a swab saturated with isopropyl alcohol to clean the end-surfaces. Use dry, oil-free compressed air after applying the isopropyl alcohol.

To clean the optical connectors, follow these steps:

Step 1 Wipe the ferrules and end-face surfaces of the connector gently with an alcohol pad from the cleaning kit. Be sure that the pad makes full contact with the end-face surfaces. Wait five seconds for the surfaces to dry and repeat.

Step 2 Blow dry the connectors with canned, dry, oil-free, compressed air.

Step 3 Use a magnifying glass to inspect the ferrule.

The connectors used inside the system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side, follows the previous directions, and ensures the following:

•Clean the connectors using lens tissues before connecting to the adapters. Use pure alcohol to remove soil.

•Do not clean the inside of the connector adapters. Do not use force or quick movements when connecting the fiber optic connectors in the adapters.

•Cover the connector adapters to avoid soiling or contaminating the inside of the adapters while cleaning the chassis. When not using the connectors, cover the connectors and adapters to avoid the inside of the adapters or the surface of the connectors from getting dirty.

Note If the surface is not clean or does not have a uniform shine, repeat the process using a fresh surface of the alcohol pad.

Powering Up the Chassis

Before powering up the chassis, the following conditions must be met:

•The system is set for the correct AC (or DC) power voltages. Refer to the Cisco ONS 15540 ESP Hardware Installation Guide or the Cisco ONS 15540 ESPx Hardware Installation Guide for power voltages.

•You must verify the rectifier status. Use a voltmeter on the DC output of the rectifier to verify the operational status of the rectifier.

•The power cables are connected to the system.

•A console terminal is connected to the system.

ONS 15540 specifications

Cisco Systems ONS 15540 is a high-capacity Optical Network System that plays a vital role in modern telecommunications by providing scalable and reliable transport solutions for service providers. Designed to accommodate the rapidly increasing demand for bandwidth, the ONS 15540 allows for seamless integration of voice, video, and data services over a single network infrastructure.

One of the standout features of the ONS 15540 is its ability to support both SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) protocols, enabling interoperability between different equipment and networks. This compatibility makes it an attractive solution for carriers looking to optimize their existing infrastructure while also preparing for future growth. The system is capable of delivering line rates of up to 40 Gbps, making it suitable for high-traffic environments.

The ONS 15540 employs advanced wavelength division multiplexing (WDM) technology, which allows multiple data streams to be transmitted simultaneously over a single optical fiber. This capability maximizes the utilization of existing fiber resources and significantly increases bandwidth availability. The system supports both CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) configurations, offering flexibility to meet diverse network needs.

Another significant characteristic of the ONS 15540 is its modular architecture. This design enables service providers to easily upgrade and expand their systems by adding new line cards or service modules without significant disruption. The ONS 15540 accommodates various types of interfaces, including Ethernet, TDM, and video, ensuring the system can support a wide range of applications.

In addition to its hardware features, the ONS 15540 includes sophisticated management capabilities through Cisco's comprehensive management tools. These tools allow network operators to monitor performance, provision new services, and perform troubleshooting efficiently. With built-in redundancy and fault-tolerant features, the system ensures high availability and reliability, critical for service providers that require 24/7 operation.

In summary, the Cisco Systems ONS 15540 optical networking system provides a robust solution for carriers seeking to enhance their network capacity and flexibility. With its support for multiple protocols, advanced WDM technology, modular architecture, and management capabilities, the ONS 15540 stands out as a powerful asset for meeting the demands of today’s communication landscape.
