D-Link DES-3250TG Standalone Layer 2 Switch
Stacking with DGS-3312SR
The DES-3250TG Release 4 Switch can be arranged in a star topology and managed as slave devices through the DGS-
3312SR Master Switch. Up to twelve Switches can be connected to the DGS-3312SR Switch in this arrangement.
Figure 4- 6. DES-3250TG Switches with DGS-3312SR
Setting up a star topology with a DGS-3312SR is a simple matter. Each DES-3250TG connects to the master through the
stacking port to a similar stacking port on a DGS-3312SR Switch equipped with one or two special stacking modules designed
for the DES-3250TG Switch. Each DES-3250TG slave must be configured with stacking mode enabled. When stacked in a
star topology arrangement with the DGS-3312SR, the Switch will automatically assume slave status. The unit number is
determined by the port number to which it is connected on the DGS-3312SR master. The DGS-3312SR must have a stacking
module installed and have stacking mode enabled as well. Stacking for the DGS-3312SR uses the identical CLI command:
config stacking mode enable. Be sure to save the configuration change using the CLI command save.
Remember that for star topology arrangements, if the stacking link to a given Switch fails or is disconnected, that Switch will
lose its status in the stack and reboot as a standalone device with the IP settings. The DGS-3312SR and remaining slave units
are not effected by the link failure.
NOTE: The DES-3250TG must have stacking mode enabled to be used with the DGS-3312SR in a
star topology arrangement.
