an IN port on one Switch to an OUT port on the next Switch in the stack.

Restrictions and Cautions for Stacking

The DGS-3312SR may serve as the Master of up to twelve additional Switches. The slave switch units must meet the

following criteria:

• All additional slave Switches must be DES-3226S or DES-3250TG Switches. The slave unit types can be mixed

within a single stacked group.

• DES-3226S or DES-3250TG slave Switches must have firmware Release IV or later loaded to operate properly

with the DGS-3312SR Master.

• The DGS-3312SR is automatically started as the Master Switch in a Switch stack.

• It is necessary to enable stacking for each slave Switch in a stacked group before interconnecting them and before

connecting the group to the network. Stacking can be enabled by connecting to each slave through the console

• Data rate up to 1000 Mbps

• 8-segment LED display to indicate Switch ID number within the Switch stack

i ch Stacking

DGS-3312SR can be stacked with a DES-3226S or DES-3250TG, functioning as the Master of the stack. There are
