Product Description

The Allied Telesis x220-52GT is the copper-port high-density member of the x220 Series, providing a comprehensive access layer solution for enterprise networks requiring reliable gigabit connectivity with Layer 3 inter-VLAN routing. The switch features 48 x 10/100/1000T auto-negotiating RJ-45 ports for workstation and device connectivity, paired with 4 x 100/1000X SFP slots that accept 100Mbps or 1G fiber transceivers for flexible uplink connectivity to distribution or core switching over multimode or single-mode fiber links. The non-blocking switching fabric operates at 104 Gbps with a forwarding rate of 77.4 Mpps — delivering full wire-speed performance at all port densities without oversubscription. The fixed single AC power supply provides reliable operation with a maximum power consumption of 47W, making this an energy-efficient choice for wiring closet deployments. Layer 3 capabilities include static routing and RIPv1/v2 for IPv4 inter-VLAN routing, with full dual-stack IPv4/IPv6 support and IPv6 Ready certification. The AlliedWare Plus operating system provides an industry-standard CLI consistent across all AlliedWare Plus devices, reducing training overhead for network operations teams managing mixed Allied Telesis environments. Allied Telesis Autonomous Management Framework Plus (AMF Plus) support enables the x220-52GT to participate in centralized zero-touch network management: devices are automatically provisioned on first connection, configurations are centrally backed up, and failed devices recover automatically without administrator intervention. Resilience is provided through EPSRing (Ethernet Protection Switched Ring) and standards-based G.8032 ERPS (with optional license) for sub-50ms ring failover in distributed campus networks. Network security features include tri-authentication (802.1x, MAC-based, web-auth), DHCP snooping, BPDU protection, STP root guard, dynamic ARP inspection, and comprehensive ACLs for multi-layered access control. Active Fiber Monitoring (AFM) on the SFP uplinks detects unauthorized optical tapping, protecting sensitive data traversing fiber infrastructure. The x220 Series carries FIPS 140-2 validation and JITC certification, making the AT-X220-52GT-10 eligible for federal government procurement alongside its enterprise campus use cases.

Frequently Asked Questions

Q: Does the AT-X220-52GT-10 support PoE?

No. The AT-X220-52GT-10 is the non-PoE model. For PoE+ (IEEE 802.3at, 740W budget, up to 30W per port), the equivalent model is the AT-X220-52GP which provides identical port counts with PoE+ capability on all 48 copper ports.

Q: What SFP transceivers are compatible with the 4 uplink ports?

The 4 SFP uplink slots accept 100Mbps and 1G SFP transceivers (mini-GBIC form factor) supporting multimode and single-mode fiber. Allied Telesis AT-SPSX, AT-SPLX10, AT-SPSXBD, and other standard 1000Base-X SFP modules are compatible. Allied Telesis recommends using approved transceivers for optimal performance.

Q: Does the x220-52GT support OSPF routing?

No. The x220-52GT supports static routing and RIPv1/v2 for IPv4, plus static routing for IPv6. OSPF is not available on the x220 Series. For environments requiring OSPF, the x530L Series with the Premium license or the GS980MX Series with additional routing features should be considered.

Q: Is this switch JITC certified for government use?

Yes. The x220 Series carries JITC certification, placing it on the DoDIN Approved Products List (APL) for use on secure U.S. Government and Department of Defense networks. The switch also carries FIPS 140-2 validation for cryptographic management security.

Q: Does the x220-52GT support stacking?

No. Unlike the x530L and GS980MX Series, the x220 Series does not support VCStack hardware stacking. Multiple units can be managed centrally through AMF as part of a unified network fabric, but they remain separate physical devices.

Q: What is Active Fiber Monitoring and which ports does it apply to?

Active Fiber Monitoring (AFM) is an Allied Telesis technology that detects unauthorized optical splicing or tapping on fiber links by monitoring optical signal characteristics. On the x220-52GT, AFM applies to the 4 x SFP uplink ports, providing security for the fiber segments connecting to the distribution layer.

Q: Where can I purchase the AT-X220-52GT-10?

The AT-X220-52GT-10 is available from Creation Networks. Visit creationnetworks.net for pricing, availability, and volume quote requests.
