1.Product Overview
ENTERASYS A4H124-24FX P0973JN is a high-performance stackable managed switch designed for industrial automation,data centers,and enterprise networks.It supports 24 100Base-FX fiber ports and 2 Gigabit SFP uplink ports,providing low latency,high reliability data transmission capabilities.Its modular architecture and rich functions are suitable for complex network environments,support multi-layer packet classification,QoS and security policies,and meet high bandwidth and low latency requirements.
2.Core functions and features
High-performance network transmission
Switching capacity:stand-alone 17.6 Gbps(up to 140.8 Gbps after stacking).
Throughput:9.5 Mpps(stand-alone),supports non-blocking line-speed forwarding.
Port configuration:24 100Base-FX fiber ports(MT-RJ interface)+2 Gigabit SFP ports,supporting fiber expansion and long-distance connection.
Stackability and scalability
Supports up to 8 switch stacks to form virtual switches,providing 384 10/100 ports and 16 Gigabit upstream ports.
Stacking method:Supports closed-loop or daisy chain connection,and redundant design avoids single point failure.
Network Management and Security
Remote management:supports SNMP,Telnet,HTTP,SSH,WebView and other protocols,and provides web interface and CLI command line management.
Safety features:
VLAN:Supports 4096 VLANs,realizing network isolation and traffic control.
QoS:Based on 802.1p priority scheduling,supports 4 hardware queues to ensure key business priorities.
Security authentication:RADIUS,802.1X,ACL port security to prevent unauthorized access.
Redundancy and reliability
Power redundancy:Supports STK-RPS-150PS redundant power system,automatically switches when the main power supply fails to ensure that the network does not interrupt.
Environmental adaptability:
Operating temperature:0°C to 50°C(commercial grade),storage temperature:-40°C to 64°C.
Protection level:Fanless design,suitable for high dust and low noise environments(such as classrooms,control rooms).
