Avaya M5504-1000SLX-F 4-Port Gigabit Ethernet Switch

Avaya Lucent M5504-1000SLX-F is a four-port Gigabit Ethernet fiber module designed for Avaya Cajun 880 chassis and the M5500 family, providing four independent 1 Gbps links via 1000BASE-SLX transceivers. Each port supports full‑duplex operation over fiber, enabling four simultaneous gigabit connections within enterprise networks and suitable for uplinks to core switches or interconnects in campus deployments. The SLX-F variant is documented in vendor and reseller references with part numbers 311-0009-002 and 530-0016-263, and is associated with Cajun 880 configurations as the M5504-1000SLX-F four‑port module. Some sources describe the module as operating at 1300 nm with full-duplex support, aligning with typical 1000BASE-SLX fiber specifications and the needs of legacy Avaya networks that rely on fiber links between switches. This module is intended for use in compatible Avaya Cajun/M5500 environments where fiber-based Gigabit interconnects are required.
