D-Link DGS-3212SR [25/224] Connecting stacked switch groups

DGS-3212SR Stackable Gigabit Layer 2 Switch

Connecting Stacked Switch Groups

The DGS-3212SR has the capability to hold twelve gigabit ports that may be used in standalone mode or can be used in a

stacking configuration to provide up to 576 10/100 Mbps ports and 12 Gigabit ports in a star architecture. For stacking, the

DGS-3212SR will be the master switch of a stack of DES-3226S switches. The instructions below, Configuring a Switch

Group for Stacking, tell you how to configure the DGS-3212SR to function as a Master, as well as how to configure the

DES-3226S to function as slave Switch units using the CLI interface.

Stacking Connections with IEEE 1394, Ethernet Cabling, and Fiber-Optic Transceiver Cabling

Figure 2-4. Star Topology Stacked Switch Group

The IEEE 1394 fire wire stacking ports are marked IN and OUT. The IEEE 1394 compliant cable must be connected from

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

NOTICE: Do not connect the stacked Switch group to the network until you have

properly configured all Switches for stacking. An improperly configured Switch

stack can cause a broadcast storm.
