ALLNET ALL-SG8420M managed switch

The ALLNET ALL-SG8420M is a managed L2 Gigabit Ethernet switch offering 16 RJ-45 ports with 10/100/1000 Mbps speeds and full duplex operation. Designed for rack mounting in a 19U form factor, the switch provides a MAC address table with capacity for 8000 entries and a switching capacity of 32 Gbit/s. Compliance with a broad set of IEEE standards ensures interoperability and predictable behaviour in mixed-vendor networks, while the black metal housing supports typical server-room installations.

Advantages

This managed switch delivers reliable Layer 2 switching with per-port Gigabit throughput and full duplex support to minimise congestion. The 8000-entry MAC table and 32 Gbit/s switching capacity allow for stable forwarding performance in small to medium enterprise environments. Support for multiple IEEE standards provides features such as link aggregation, flow control and Quality of Service, enabling integration into existing network topologies and traffic management policies.

Suitable for

• Small and medium office networks requiring managed Layer 2 switching
• Rack-mounted network installations in server rooms or communications cabinets
• Network edge deployments where multiple Gigabit endpoints need centralised switching
• Environments needing standard IEEE features like link aggregation and QoS

How to use

Install the ALLNET ALL-SG8420M into a standard 19U rack using appropriate mounting brackets and secure the device power and network cabling. Configure the switch via its management interface according to your network plan: assign VLANs, set up link aggregation where required, and apply QoS policies to prioritise traffic. Ensure each connected device uses appropriate Ethernet cables rated for Gigabit speeds and verify link status per port after configuration. Regularly save and back up the switch configuration to preserve settings.

Recommendations

Place the switch in a temperature-controlled rack environment with adequate ventilation and maintain proper cable management. Use Cat5e or higher twisted-pair Ethernet cabling for Gigabit links. When deploying in a managed network, plan VLAN and QoS configurations in advance and enable flow control or link aggregation only where endpoints support those features.
