Foxboro P0973JN is a high-performance 24-port fiber management switch,belonging to the A4 series,designed for scenarios such as telecommunications,data centers,and industrial automation,providing efficient data transmission and network management capabilities.The following is a comprehensive overview of its core functions and technical parameters:
I.Product Overview
Port configuration:24 100Base-FX fiber ports(MT-RJ connectors)+2 fixed RJ-45 10/100/1000 stacking/uplink ports+2 1000Base-X SFP Gigabit uplink ports,supporting Mini-GBIC module expansion.
Switching capacity:17.6 Gbps,supporting 24 10/100 Ethernet ports and 4 Gigabit Ethernet uplink ports,suitable for high-performance data exchange in small and medium-sized networks.
II.Technical parameters
Network performance
-Standard compatibility:Complies with IEEE 802.3u(Fast Ethernet),IEEE 802.1w(Rapid Spanning Tree Protocol),IEEE 802.3x(Flow Control)and other standards.
-Full-duplex operation:Supports full-duplex mode to improve data transmission efficiency.
-Stacking function:Stacking is achieved through the RJ-45 port,supporting up to 8 switches cascaded to form a virtual switch with a total capacity of up to 140.8 Gbps.
Redundancy and reliability
-Power redundancy:Supports optional external redundant power supply module(RPSM).When the internal power supply fails,the external power supply takes over seamlessly to ensure continuous operation of the network.
