Cisco IE 3000 Switch Hardware Installation Guide

Appendix B Installation In a Hazardous Environment
Adding Modules to the Switch
Expansion Module Configurations
To increase the number of ports, add one or two expansion modules to the switch. If you are installing
only one module, it can be either a Cisco IEM-3000-8TM or a Cisco IEM-3000-8FM. If you are
installing two modules, the first must be a Cisco IEM-3000-8TM, and the second can be either a Cisco
IEM-3000-8TM or a Cisco IEM-3000-8FM. You cannot add two Cisco IEM-3000-8FM expansion
modules.
Table B-1 lists the port combinations using switch and expansion modules.
Figure B-1 shows example combinations of the Cisco IE-3000-4TC switch and expansion modules. Even
though the example configurations in Figure B-1 show a Cisco IE-3000-4TC switch, the same
combinations of expansion modules can be used with a Cisco IE-3000-8TC switch.
