Tools and Equipment

Obtain these necessary tools and equipment:

Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches
(lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure.

Installation Guidelines

Observe these guidelines when removing or installing a fan module:

• Do not force the fan module into the slot. This can damage the pins on the switch if they are not

aligned with the module.

• A fan module that is only partially connected to the switch can disrupt the system operation.

• The switch supports hot swapping of the fan module. You can remove and replace the module

without interrupting normal switch operation.

• When replacing the fan module, complete the replacement procedure within 2 minutes to avoid

overheating the switch.

• Make sure that all fan module captive screws are tightened before moving the switch.

Fan Module Installation

Warning

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Installing a Fan Module

To remove and install a fan module, follow these steps:

Step 1 Use a number-2 Phillips screwdriver to loosen the two captive screws that secure the fan module to the

switch chassis.

Caution You should replace the fan module within 2 minutes to avoid overheating the switch.

Step 2 Remove the fan module from the fan slot by pulling on the extraction handle.

Step 3 Insert the new fan module into the fan slot, and gently push the module into the slot (Figure 2). When

correctly inserted, the fan module is flush with the switch rear panel.

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

Documentation Feedback

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:

http://www.cisco.com/go/psirt

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:

Reporting Security Problems in Cisco Products

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— [e-mail]

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 — [e-mail]

78-17571-01

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

Obtaining Technical Assistance

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 Cisc o . PSIRT can work w i t h 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:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

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.

Obtaining Technical Assistance

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.

Cisco Technical Support & Documentation Website

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:

http://www.cisco.com/techsupport

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:

http://tools.cisco.com/RPF/register/register.do

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.

Submitting a Service Request

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:

http://www.cisco.com/techsupport/servicerequest

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: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Obtaining Additional Publications and Information

Definitions of Service Request Severity

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.

Obtaining Additional Publications and Information

Information about Cisco products, technologies, and network solutions is available from various online
