Contacting Extreme Technical Support
The Extreme Networks Global Technical Assistance Centers (TACs) are the focal point of contact for
post-sales technical and network-related questions or issues. Extreme Networks maintains several TACs
around the world. If you have a network issue that you are unable to resolve, contact the nearest
Extreme Networks TAC. The TAC will create a service request (SR) and manage all aspects of the
service request until the question or issue that spawned the service request is resolved.
