Introduction

Gigabit Fiber Edge Switch
The Allied Telesis x220-28GS is a fully managed high-performing Gigabit Layer 3 switch. The combination of 24 x 100/1000X SFP slots, and 4 x 100/1000X SFP uplinks make it ideal for sensitive data transfer and long-distance fiber connectivity at the edge of the network.
