Description

The Extreme Networks A4H254-8F8T switch is a feature rich and highly reliable fast Ethernet edge switch, with the following detailed features:

1、 Basic specifications
Port configuration: This switch has 8 100Base FX fiber optic ports (SFP) and 8 10/100Mbps RJ-45 copper cable ports, allowing users to flexibly connect different types of network devices and meet diverse network needs.
Stacking capability: Supports stacking function, up to 8 A4H254-8F8T can be interconnected in a single stack to create a virtual switch, providing up to 140.8 Gbps capacity and up to 384 10/100 Ethernet ports as well as 16 Gigabit Ethernet uplink ports.
2、 Performance characteristics
Line speed performance: Provides scalable line speed performance to support the bandwidth intensive and latency sensitive requirements of today’s demanding applications.
Quality of Service (QoS): Supports traffic control and priority settings to ensure that different types of data flows are given reasonable priority processing, in order to provide better service quality. This is particularly important for integrated multimedia networks (such as IP voice and video) and data intensive applications.
Intelligent queuing mechanism: Combined with its non blocking L2 switching architecture, the intelligent queuing mechanism of A4H254-8F8T ensures that critical task applications have priority access to network resources.

3、 Advanced features
Virtual Local Area Network (VLAN): Provides VLAN functionality, allowing the network to be divided into multiple logical partitions according to requirements, increasing network flexibility and security.
Security: Supports access control list (ACL) and port security functions, which can restrict network access and protect network security. At the same time, it supports IEEE 802.1X, MAC addresses, or web-based authentication, providing port level or user level security controls.
Network Management: Supports SNMP (Simple Network Management Protocol) and other network management protocols to facilitate monitoring, configuration, and management of switches.
4、 Reliability and redundancy
Redundant power supply: This switch has a redundant power supply design to ensure the continuous operation of the network in the event of a power failure.
Redundant link aggregation: Supports redundant link aggregation function, which transmits data in parallel through multiple physical links to improve the reliability and fault tolerance of the network.
5、 Other characteristics
Lifetime warranty: All A-series products come with lifetime warranty services, including advanced hardware returns, firmware feature upgrades, and phone support, which can significantly reduce customers’ operating costs throughout their network lifecycle.
Applicable scenarios: Due to its high reliability and rich features, the A4H254-8F8T switch is very suitable for large and medium-sized enterprises that need to support thousands of terminals, as well as network environments that require high performance and reliability.
