Cisco Systems 1800 Series 13

Usingthe 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 TACService Request Tool automatically provides recommended solutions. If your issue is not resolved using the

recommendedresources, your service request will be assigned to a Cisco TAC engineer. The TACService Request Tool is located

at this URL:

ForS1 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 TAC 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

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Yournetwork 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

negativelyaffected 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 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)—Yourequire information or assistance with Cisco product capabilities, installation, or configuration. There is

little or no effect on your business operations.
