THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORT H IN THE INFORMATION PACKET T HAT 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 accor dance 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 ener gy. 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 Cisc o’s writ ten author ization m ay resul t in the equi pment no lo nger comp lyi ng with FCC requi rements for Class A or Class B digital devices. In that event, your right to use the equ ipment may be limit ed by FCC regul ations , and you may be requir ed to correct a ny 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 interferen ce stops, it was probably caused by the Cis co equipm ent 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 unt il the int erference st ops.

• Move the equipment to one side or the other of the televisio n or radi o.

• Move the equipment farther away from the te levision or radio.

• Plug the equipment into an outlet that is on a di fferent cir cuit from the televi sion o r radio. (That is, make certain th e equipment and the te levision or radio are on circuit s controlled by different circuit breaker s or fuses.)

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The avenue of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,

product installation, or basi c product configuration.

• Priority level 3 (P3)—Your network perform ance is degrade d. Network fu nction ality is not iceabl y

impaired, but most business operations continue.

• Priority level 2 (P2)—Your production ne twork is severely degraded, affect ing significant asp ects

of business operations. No workar oun d is available.

• Priority leve l 1 (P1)—Your production network is down, and a critical impact to business operations

will occur if se rv ice is n ot r esto re d qui ck ly. No workaround i s available.

Cisco TAC Website

You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-t he-c lock acc ess t o on lin e tools, kn owledge ba ses, an d so ftware . To access the Cisco TAC website, go to this URL:
