Description

Bay Networks 5431 ESAF-4 Dual Sync Ethernet Module BCN BLN P106741

Dual synchronous Ethernet network module designed for Bay Networks BCN and BLN routers. Provides four ports for expanded connectivity in enterprise routing environments.

Specifications & What's Included

  • Model: Bay Networks 5431 ESAF-4
  • Part Number: P106741
  • 4 Ports: 2x XCVR (DB-15), 2x COM (DB-25)
  • Interface: Synchronous Ethernet
  • Compatible: BCN and BLN routers
  • Form Factor: Card/Module
  • Manufactured: United States

Applications

This module was used in enterprise and service provider networks to add synchronous Ethernet connectivity to Bay Networks routing platforms. The dual transceiver and COM ports supported WAN connectivity and serial management functions in BCN/BLN deployments. Commonly installed in late 1990s and early 2000s telecommunications infrastructure for carrier-class routing and protocol conversion.

Condition: Used
This Bay Networks 5431 ESAF-4 Dual Sync Ethernet Module has been inspected and is in good used condition. It was pulled from a working BCN/BLN router environment where it was actively in service. The PCB and components look clean with no obvious damage. The metal faceplate and port connectors — including both XCVR DB-15 and COM DB-25 ports — show normal handling wear consistent with prior rack installation. Please view our photo set and contact us if you have any questions.
