SSIM-T5-04 Module Package Contents
The interface module package contains the following items:
•One
•One
Installation
1.Power off the base switch by unplugging it.
2.Remove the plate covering the expansion slot on the front of the base switch by unscrewing the two retaining thumbscrews. Keep the plate for use in the event that the interface module is removed.
3.Carefully insert the interface module into the rails on each side of the expansion slot, sliding it back until the connector on the interface module is seated into the connector at the back of the slot.When the interface module is fully seated, the interface module faceplate will be flush with the front of the base switch.
4.Secure the interface module with the two attached thumbscrews.
Cabling
For specifications and directions about cabling the UTP/STP universal expansion modules, see Appendix B in SmartStack

Testing the interface module
1.Power on the base switch to start diagnostics. The STS16- 20RM Token Ring switch indicates that diagnostics are in progress by turning on its DIAG LED. After about a minute, the interface module DIAG LED will also be turned on.
2.Verify that the base switch diagnostics have been completed successfully. On the
3.Verify that the ERR LED on the interface module is off. If it is off, diagnostics have been successfully completed, and the interface module is ready for configuration.
Configuration
The interface module ports can be configured just like the base switch ports. They will appear as additional ports on any configuration panel where ports are listed. The port numbers will begin where the numbers of the base switch stop.
If for example the base switch has 20 ports and an interface module in the left front panel slot, the interface module ports will appear after Port 20 on the various port configuration panels and be designated 21, 22, 23 and 24. If the module is in the right front panel slot, the ports will be designated 25, 26, 27 and 28.
