SmartStack STS-LM Connectors and LEDs
The following tables describe the connectors and LEDs on the STS-LM front 
panel.
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.
