8 Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco
Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical
Support Website on Cisco.com features extensive online support resources. In addition, Cisco
Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid
Cisco service contract, contact your reseller.
Cisco Technical Support Website
The Cisco Technical Support 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, 365 days a year, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support 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 Website by clicking the Tools & Resources link under Documentation &
Tool s. 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.
