ENTERASYS A2H254-16-RH Ethernet switch

Description

Interface and Port
Total number of network ports: 16, including 8 10/100Base TX LAN ports (RJ-45 interface), used to connect twisted pair devices, supporting 10Mbps and 100Mbps Ethernet rates; 8 100Base FX LAN ports (MT-RJ interface), used to connect devices through fiber optics, providing 100Mbps Ethernet connection, suitable for long-distance transmission or environments that require electromagnetic interference resistance.
Stacking ports: 2, used to stack multiple A2H254-16-RH switches together to expand the number of ports and enhance network performance, up to 8 A2 series switches can be stacked.
SFP interface: 2 small form factor pluggable (SFP) interface slots that can accommodate mini GBIC modules, providing gigabit Ethernet expansion capabilities and supporting gigabit Ethernet connections with multiple fiber or copper media, increasing network connectivity flexibility.
Networking and Communications
Supported network layer: Layer 2 (data link layer), supports Ethernet layer 2 switching functions such as MAC address learning, VLAN partitioning, spanning tree protocol, etc., and can build a stable and reliable local area network.
Standard memory: 128MB DRAM, used to store the operation configuration, MAC address table, and other data of the switch, ensuring that the switch can quickly process network packets.
Flash memory: 16MB, used to store the operating system, configuration files, etc. of the switch for easy startup and operation.
other characteristics
Management function: Supports Enterasys Networks’ Netsight management system, which enables centralized management and monitoring of switches, facilitating network administrators to configure, troubleshoot, and optimize performance.
Redundant power supply support: Supports redundant power supply to improve the reliability and stability of the switch. When one power supply fails, the other power supply can continue to supply power to the switch, ensuring uninterrupted network services.
Dimensions: It can be used as a desktop switch or rack mounted with an installation kit (including two mounting brackets and eight M3x6mm screws) to adapt to different installation environments and space requirements.
Electrical characteristics: The current is 0.5A at a working voltage of 110V and 0.47A at 220V.
