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 & 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.
