All xStack Switches Backed by Limited Lifetime Warranty
D-Link stands behind the xStack switch family with unlimited technical support, free firmware upgrades, and a limited lifetime warranty.

The D-Link xStack DXS-3326GSR is designed to meet the most demanding high port density fiber requirements. Each unit provides 24 Gigabit fiber slots with four Combo 10/100/1000Base-T ports, and switching capacity of 128Gbps. D-Link xStack switches can stack up to 12 units in a stack**, providing up to 384 Gigabit ports, and up to 40Gbps of shared stacking bandwidth in a ring topology or 20Gbps of dedicated stacking bandwidth in a "star" topology. The DXS-3326GSR stacks with the other xStack Switches including the DGS-3324SR, DGS-3324SRi, DXS-3350SR, and DES-3352SR, providing unprecedented flexibility in a switch stack environment.

DXS-3350SR - 48-Port 10/100/1000 Managed Stackable Layer 2/3/4 Switch with (4) Combo SFP Ports, Integrated 10-Gig Stacking, and Optional 10-Gig Uplinks

The D-Link xStack DXS-3350SR provides 48 built-in copper Gigabit ports, including (4) Combo SFP ports supporting either copper links or SFP adapters for easy, flexible connection to fiber-based Gigabit media. In a ring stacking topology it can provide up to 384 Gigabit ports, up to 40Gbps of stacking bandwidth, and a switching capacity of up to 176Gbps per unit. It also stacks with the other xStack Series switches including the DGS-3324SR, DGS-3324SRi, DXS-3326GSR, and DES-3352SR, to provide unprecedented flexibility in a switch stack environment.
