¥9,999.00

The Enterasys A2H254-16 P0973BK is a Fast Ethernet switch from Enterasys Networks (later acquired by Extreme Networks), part of the A2 series of fixed-configuration switches designed for enterprise and industrial network edge deployments. The A2H254-16 P0973BK provides 16 Fast Ethernet ports, making it suited to smaller access-layer segments, remote wiring closets, and industrial network cabinets where a compact port count is sufficient. The switch is built for reliable continuous operation and supports the stable connectivity that plant and building networks depend on. The A2H254-16 P0973BK is typically deployed at the access layer, aggregating end devices and uplinking to higher-layer switches. For organizations maintaining legacy Enterasys network infrastructure, the A2H254-16 P0973BK serves as an important spare, helping preserve network availability where replacement with current-generation platforms is not immediately practical.

Comparison with Competing Products

Compared with current-generation switches, the Enterasys A2H254-16 P0973BK offers continuity for existing Enterasys network designs, avoiding the reconfiguration effort of a platform migration. Competing modern switches provide higher throughput and updated management features, but may require redesign of VLAN, spanning tree, and management configurations. Where the existing network is standardized on Enterasys equipment, the A2H254-16 P0973BK minimizes disruption and preserves operational familiarity.

Selection Suggestions

Confirm the port type and connector arrangement match your existing cabling.
Verify compatibility with your network management and VLAN configuration.
Review uplink requirements to higher-layer switches.
Consider stocking a spare A2H254-16 P0973BK where legacy Enterasys equipment remains in service.
Consult Enterasys/Extreme documentation for firmware and configuration details.

Precautions

Install only with power disconnected and follow network cabinet safety procedures.
Observe ESD precautions when handling the switch.
Verify firmware version compatibility with your network design.
Confirm cabling and connector types before connection.
Note that vendor support lifecycle for legacy platforms should be verified before relying on long-term availability.
