The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This guide describes how to clean all multiferrule (MT) optics in a Cisco CRS-1 Carrier Routing System Multishelf System using the Cisco CRS-1 fiber-optic cleaning kit. This kit cleans all optics on the S2 module, S13 module, optical interface module (OIM), and optical array cables.
The preface contains the following sections:
•Related Cisco CRS-1 Documentation
•Cisco Product Security Overview
•Obtaining Technical Assistance
•Obtaining Additional Publications and Information
This guide provides instructions for properly cleaning dust and contaminates from the fiber-optic connections in a Cisco CRS-1 multishelf router. All connections must be clean because even microscopic particles can cause failure of the component or entire system.
This guide is intended for service personnel, field service technicians, and hardware installers who will be cleaning the fiber-optic connections.
This guide contains the following chapters and appendixes:
•"Overview," provides an overview of the fiber-optic connections in the Cisco CRS-1 multishelf system. This chapter also summarizes the process for cleaning the connections and includes an overview of the Cisco CRS-1 fiber-optic cleaning kit.
•"Cleaning the Optical Array Cable Connectors," provides instructions for cleaning the ferrules in the optical array cable connectors. These connectors are at both ends of the fiber-optic cables that connect the S13 cards in the line card chassis to the OIMs in the fabric card chassis.
•"Cleaning the Bulkhead Array Connectors," provides instructions for cleaning the optical array connectors located on the S13 cards in the line card chassis to the OIMs in the fabric card chassis.
•"Cleaning the S2 HBMT Connectors," provides instructions for cleaning the high-density backplane-mounted (HBMT) connectors on the rear of the S2 cards in the fabric card chassis.
•"Cleaning the OIM HBMT Connectors," provides instructions for cleaning the HBMT connectors on the rear of the OIMs in the fabric card chassis.

Cisco provides a free online Security Vulnerability Policy portal at this URL:
From this site, you will find information about how to:
•Report security vulnerabilities in Cisco products.
•Obtain assistance with security incidents that involve Cisco products.
•Register to receive security information from Cisco.
A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:
To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:
•For Emergencies only — email@example.com
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•For Nonemergencies — firstname.lastname@example.org
In an emergency, you can also reach PSIRT by telephone:
•1 877 228-7302
•1 408 525-6532
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:
The link on this page has the current PGP key ID in use.
If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.
Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.
The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
Information about Cisco products, technologies, and network solutions is available from various online and printed sources.
