The Allied Telesis x220 Series are fully-managed high-performing Gigabit Layer 3 switches. Integrated security features, plus 28 SFP or 48 Gigabit copper ports, make them the ideal choice for long-distance fiber or high-density copper connectivity at the edge of the network.

The x220-28GS features 24 x 100/1000X SFP slots and 4 x 100/1000X SFP uplinks to provided extended reach at the network edge in distributed environments. Secure data transfer is ensured with Allied Telesis Active Fiber Monitoring (AFM) preventing data eavesdropping on all short and long-distance fiber links.

The x220-52GP/GT have 48 x 10/100/1000T RJ-45 copper ports and 4x 100/1000X SFP uplinks. The Power over Ethernet Plus (PoE+) model (52GP) is an ideal solution for connecting and remotely powering wireless access points, IP video surveillance cameras and IP phones.

A comprehensive feature-set provides an excellent access solution for today’s networks, with high performance gigabit throughput.

Resilient
Allied Telesis Ethernet Protection Switched Ring (EPSRing™) enables distributed network segments to have resilient high-speed access to online resources and applications, and provides continuous traffic flow even during unscheduled outages.

Powerful network management
Meeting the increased management requirements of modern converged networks, Allied Telesis Autonomous Management Framework™ (AMF) automates many everyday tasks including configuration management. The entire network can be managed as a single virtual device with powerful centralized management features. Growing the network can be accomplished with plug-and-play simplicity, and network node recovery is fully zero-touch.

AMF secure mode increases network security with management traffic encryption, authorization and monitoring.

Secure
Network security is guaranteed, with powerful control over all traffic types, secure management options, and other multi-layered security features built right into the x220 Series.

Network Access Control (NAC) gives unprecedented control over user access to the network, successfully mitigating threats to network infrastructure.

The x220 Series use 802.1x port-based authentication, in partnership with standards-compliant dynamic VLAN assignment, to assess a user’s adherence to network security policies and either grant access or offer remediation. Tri-authentication ensures the network is only accessed by known users and devices. Secure access is also available for guests.

Security from malicious network attacks is provided by a comprehensive range of features such as DHCP snooping, STP root guard, BPDU protection and access control lists. Each of these can be configured to perform a variety of actions upon detection of a suspected attack.

Network protection
Advanced storm protection features include bandwidth limiting, policy-based storm protection and packet storm protection.

Network storms are often caused by cabling errors that result in a network loop. The x220 Series provides features to detect loops as soon as they are created. Loop detection and thrash limiting take immediate action to prevent network storms.

Effortless management
The x220 Series runs the advanced AlliedWare Plu™ fully featured operating system, delivering a rich feature set and an industry-standard Command Line Interface (CLI). This reduces training requirements and is consistent across all AlliedWare Plus devices, simplifying network management.

The web-based Graphical User Interface (GUI) is an easy-to-use and powerful management tool, with comprehensive monitoring facilities.
