IEM-3400-8S Description
IEM-3400-8S is a Cisco Catalyst IE3400 Rugged Series expansion module for IE-3400-8T2S and IE-3400-8P2S industrial switch base systems, adding eight Gigabit Ethernet SFP ports when a deployment needs fiber-facing access or uplink interfaces instead of copper expansion. Cisco identifies this module as a non-PoE add-on, documents support for advanced hardware features on the IE3400 platform, and states in the IE3x00 hardware installation guide that expansion modules are installed with the switch de-energized rather than hot swapped.

Application Scenarios
IEM-3400-8S fits IE3400 installations that need eight additional SFP-based Gigabit links for uplink separation or media plans that should not use copper expansion ports.
Use the 8S module when the endpoint or uplink plan requires SFP interfaces; IEM-3400-8T stays in the data-only copper role, and IEM-3400-8P is the PoE copper alternative.
Schedule the expansion-module work with the switch de-energized, because Cisco documents the IE3x00 expansion modules as not hot-swappable and warns against attaching them while powered.

- In an IEM-3400-8S vs IEM-3400-8T comparison, both are IE3400 8-port expansion modules, but the confirmed difference is port media: IEM-3400-8S uses GE SFP ports and IEM-3400-8T uses GE copper ports.
- The IEM-3400-8S vs IEM-3400-8P difference is both media and PoE role, because the current SKU is non-PoE SFP expansion while IEM-3400-8P adds PoE/PoE+ copper ports.
- For an IEM-3400-8S vs IEM-3300-8S comparison, the table separates the IE3400 and IE3300 families and shows advanced hardware features as Yes for IEM-3400-8S and No for IEM-3300-8S.
- Buyers deciding which model to choose should verify the base switch first, then use the media, PoE, and advanced-hardware rows to keep the expansion module aligned with the cabinet design.
Selection Guide
1. Select IEM-3400-8S for SFP expansion
Choose this SKU when the IE3400 base system needs eight added Gigabit Ethernet SFP ports instead of RJ-45 copper expansion.
2. Keep copper expansion out of SFP BOMs
Use IEM-3400-8T only when the additional eight ports should be data-only copper, and use IEM-3400-8P only when PoE or PoE+ copper endpoint power is required.
3. Confirm the IE3400 base switch
Match IEM-3400-8S with an IE-3400-8T2S or IE-3400-8P2S base switch before releasing the quote or spare-module line.
4. Plan SFP media and installation timing together
Review the SFP module list, single-module mechanical position, and powered-down service window before the module is staged for the site.
