Avaya 108563339 P-series/Cajun switching and IP Office telephony Power Supply

The Avaya 108563339 is a backup power supply for the Avaya Cajun P330 Stackable Switch family, providing a secondary power feed so a P330-series unit keeps running if its primary internal supply fails. It is designed to sit alongside the switch’s built-in supply rather than replace it, adding N+1 resilience to an existing P330/P333 stack without any change to the switch’s configuration, and is interchangeable across the P330 and P333-series stackable switch models of this generation, which remain in service across many established enterprise networks. Genuine units such as this one are a routine requirement for maintaining full resilience on an established Cajun deployment. Tech-Star (UK-based, shipped worldwide) supplies Avaya components for ongoing network maintenance.
