Extreme Networks A4H124-24FX P0973JN Port Fiber Managed Stackable Switch

Description

• Protocol Compliance
  • Complies with multiple IEEE standards, including IEEE 802.3u, IEEE 802.3i, IEEE 802.3z, IEEE 802.1d, IEEE 802.1q, IEEE 802.3ad (LACP), IEEE 802.1w, IEEE 802.1x and IEEE 802.1ab (LLDP).

Function Features

• Stackable & Scalable Performance

  It is a stackable switch that can be expanded to a maximum of 8 A4 series modules. When stacked, it can provide a total capacity of 140.8 Gbps, along with 384 10/100 Ethernet ports and 16 gigabit Ethernet ports, meeting the needs of large – scale network expansion.

• Comprehensive Network Management

  Supports multiple remote management protocols such as SNMP (v1/v2/v3), RMON, Telnet, HTTP, TFTP and SSH. It also offers CLI and web – based management interfaces, enabling users to flexibly configure, monitor and maintain the switch remotely according to their preferences.

• Robust Network Security & Traffic Control

  Supports up to 4096 VLANs based on the IEEE 802.1Q standard, facilitating network segmentation to enhance data isolation. It includes quality of service (QoS) and Differentiated Services (DiffServ) support for traffic prioritization. It also provides access control lists (ACL), port security and RADIUS authentication to prevent unauthorized network access.

• Reliable Redundancy & Stability

  Supports spanning tree protocols including STP, RSTP and MSTP, which prevent network loops and ensure redundant network paths. Features like link aggregation control protocol (LACP) improve link reliability and bandwidth utilization. IGMP snooping optimizes multicast traffic transmission, reducing unnecessary network bandwidth occupation.

• Practical Auxiliary Functions

  Comes with flow control, port mirroring and syslog support features. Flow control helps avoid data loss during high – speed data transmission. Port mirroring enables network administrators to monitor traffic for troubleshooting. Bootp support simplifies device configuration and deployment processes.

Application Scenarios

• Industrial Automation Networks

  It is highly compatible with Foxboro I/A series control systems. It can be deployed in industrial sites to connect industrial control equipment, sensors and terminal devices. Its EMI – immune fiber ports ensure stable data transmission in harsh industrial environments with strong electromagnetic interference, supporting the normal operation of industrial automation control systems.

• Enterprise Local Area Networks (LANs)

  Suitable for medium and large enterprises to build internal office networks. It can connect a large number of office devices such as computers, printers and servers. The stackable feature allows it to expand ports as the enterprise scales up, and the QoS function ensures the smooth operation of key business applications such as video conferences and office software.

• Data Center Access Layers

  Serves as an access – layer switch in small and medium – sized data centers. It connects servers and storage devices to the core network. Its jumbo frame support improves the efficiency of large – volume data transmission between devices. Meanwhile, redundant power and network path designs reduce the risk of data transmission interruptions, ensuring the stable operation of the data center.

• Critical Infrastructure Networks

  Applied in critical infrastructure fields such as energy and transportation. These fields have strict requirements for network stability and security. The switch’s reliable performance, security functions and redundant design can meet the communication needs of critical infrastructure, ensuring the continuous and safe operation of related systems.
