Avaya P5500RFT-SWB Routing Fault Tolerant Switch

The Avaya-Lucent P5500RFT-SWB Routing Fault Tolerant Switch is a member of the Cajun P5500 multiservice switch family, built for enterprise networks that require continuous routing availability. The device is cataloged as P5500RFT-SWB with part number 540-0031-061 and is described in historical listings as a Cajun P5500RFT-SWB multiservice fault-tolerant switch. As a routing fault-tolerant switch, it is designed to maintain data paths in the face of component or link failures, enabling high-availability operation in core or distribution network layers. This model reflects Avaya-Lucent's legacy approach to integrated routing and switching in a single chassis, offering fault-tolerant routing capabilities within a multiservice platform. In practice, networks deploying this class of equipment aim to preserve service continuity while simplifying topology and management, making the P5500RFT-SWB a potential fit for organizations seeking resilience and predictable failover behavior in demanding environments.
