D-Link DGS-3212SR [27/224] Unit id display for switches in a switch stack

DGS-3212SR Stackable Gigabit Layer 2 Switch

DGS-3212SR:4#config stacking mode enable

Command: config stacking mode enable

The new stacking mode configuration must be saved and the system restarted

to put the new settings into effect.

If you do not save the changes now, they will be lost.

Saving all configurations to NV-RAM... 15%

Changing the stacking mode in the DGS-3212SR will automatically save the settings and restart the system. It will take a

few minutes to complete the process.

Unit ID Display for Switches in a Switch Stack

The Stack ID 7-segment LED (as shown below) on the front panel of the DGS-3212SR will always display F (15 in hex).

An F will also be displayed in the Stack ID LED even if the DGS-3212SR is in standalone mode.

Figure 2-5. DGS-3212SR Front Panel

The Unit ID of individual DES-3226S Switches in a Switch stack is determined by the port number of the port on the

DGS-3212SR to which the Switch is connected. The ports on the DGS-3212SR are numbered starting with port 1 from left

to right along the front panel of the Switch. For example, the four combination ports next to the Stack NO. LED are

numbered 1 through 4, so if a four port stacking module is installed in the first module slot, the stacking ports will be

numbered 5 through 8. If two stacking modules are installed in the DGS-3212SR, then the stacking ports on the second

module will be numbered 9 through 12.

Figure 2-6. DEM-540 Stacking Module Front Panel

If the a stacking module is installed in the DGS-3212SR’s first module slot, then the first IN/OUT pair in the figure above

will be port 5. If a DES-3226S in a Switch stack is connected to the first stacking port (port number 5 on the

DGS-3212SR), then the Unit ID of the DES-3226S will be 5.

The Unit ID of the DES-3226S will be displayed in the STACK NO. LED on the front panel of the DES-3226S’s stacking

module, as shown below.
