D-Link DGS-3312SR [17/290] Stacking led indicators

DGS-3312SR Stackable Gigabit Layer 3 Switch

NOTICE: The Stack ID LED on the Switch’s front panel will display an F,

regardless of the Switch’s stacking mode (Master Switch in a Switch stack,

or Standalone mode).

Stacking LED Indicators

Stacking LED indicators include the Stack ID indicator on the front panel and the Link/Act indicators on the front of the

DEM-540 stacking module.

NOTICE: The four build-in combination ports on the front panel of the

DGS-3312SR can be configured as stacking ports using the CLI.

odule has a single Link/Act LED indicator on its front panel for each IEEE 1394 IN/OUT pair. Each IEEE 1394 stacking m

Link/Act

The Link/Act LEDs have the same function as the corresponding LEDs for the

Switch’s built-in Gigabit Ethernet ports. The Link LED lights to confirm a valid link,

while the Act LED blinks to indicate activity on the link.

Stack ID

Switch group. An “F” indicates the Switch is acting in the capacity of a master Switch

of a stacked group of DGS-3312SR/DES-3226S/DES-3250TG Switches. The

remaining slave Switches in the group will display a corresponding stack number (1-

C) to indicate the logical position of the slave Switch in the stacked group. See the

discussion of Switch Stacking below for more information on stacking DGS-

3312SR/DES-3226S/DES-3250TG Switches.

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.
