THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

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: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

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)—Your 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 operation 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.
OL-11497-03
Severity 3 (S3)—Operational performance of your network is impaired, but 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.
