xStack The Ultimate Stackable Alternative to Meet Your Chassis Requirements D-Link's next-generation switches xStacks are high port-density Layer 3 stackable switches that combine the ultimate performance with fault tolerance, security, management functions with flexibility and ease-of-use. All these features typically found in the more expensive chassis-based solutions, at the price of a stackable! Fault Tolerant Star Stacking 10G Uplinks 10 Times the Speed of Gigabit*
Each D-Link xStack switch is equipped with 2 stacking ports
D-Link xStack provides the 10G uplinks for transmission at 10
providing 20Gbps full duplex bandwidth. Up to 6 xStack
times the speed of a Gigabit port. The 10G uplinks are available
switches can be stacked with a Stacking Master, itself equipped
as optional modules each equipped with 2 XFP compliant slots,
with 6 stacking ports providing 120Gbps aggregated stacking
