Connecting the Stacker Link Cable

When connecting two or more stacker link modules together to form a stack, you must use the proprietary 50-pin cable supplied with the module.

The SmartStack STS16-20D/STS16-20R switch can be configured in three different ways to form a stack of switches:

Two of the SmartStack STS16-20RM family switches back-to-back via two SmartStack STS-LM modules

Up to five SmartStack STS16-20RM family Switches via one SmartStack STS-5SU Stack Link Module and up to four SmartStack STS-LM Modules.

Up to eight SmartStack STS16-20RM family Switches via one SmartStack STS-8SU Stacker Unit and up to eight SmartStack STS-LM Modules.

When inserting the cable connector, keep the connector straight to minimize the risk of bent or damaged pins.

Note: Stacked SmartStack STS16-20RM family switches must all have the same software version.
