IEM-3400-8T Description

The IEM-3400-8T is a Cisco Catalyst IE3400 Rugged Series expansion module that adds data-only copper ports to an IE-3400-8T2S or IE-3400-8P2S industrial switch. The module has eight Gigabit Ethernet RJ45 ports without PoE, draws 12W and takes the system to 18 ports. Because the module is built for the IE3400, SGT/SGACL stays available on the base switch, which does not hold when an IEM-3300 module is attached.

Application Scenarios

Copper Ports For Controllers

In a machine-line cabinet, the module gives an IE3400 base switch eight more RJ45 ports for PLCs, drives and HMIs that need data connections only.

Segmentation-Ready Port Growth

A site that uses SGT/SGACL on its IE3400 switches adds copper ports with this module, since it keeps those features available on the base switch.

IEM-3400-8T is the non-PoE copper module of the IEM-3400 group: it adds eight Gigabit copper ports at 12W to IE-3400-8T2S and IE-3400-8P2S bases, while IEM-3400-8P adds PoE/PoE+ on the same ports but fits only IE-3400-8P2S. Cabinets that need fiber on the added ports take IEM-3400-8S with eight SFP ports at 27W. IEM-3300-8T is the lower-power copper alternative at 6W and also fits IE-3300 bases, but its advanced hardware features are listed as No against Yes for IEM-3400-8T, and Cisco notes that an IEM-3300 module on an IE3400 base makes SGT/SGACL unavailable. All four modules give 18 ports in total and none supports 90-W PoE.

Ordering Checklist

  • Supported hosts: Pair the module with the IE3400 base switches IE-3400-8T2S and IE-3400-8P2S. The module is built for the IE3400 bases; the IE3300 bases take the IEM-3300 modules instead.

Questions & Answers

  • Can IEM-3400-8T be used in a Catalyst IE3500 switch?

    No. Per the Cisco IE3x00 release notes for the module family, the IE3500 has its own module family named IEM-3500-xx. IEM-3400-8T belongs with the IE3400 base switches, so an IE3500 order needs a module from the IEM-3500 family instead of this one.
  • What are the size, weight and mounting of IEM-3400-8T?

    IEM-3400-8T measures 6 x 2.6 x 5.3 in. (15.2 x 6.6 x 13.5 cm) and weighs 0.9 kg (2.0 lb). It mounts on DIN rail. Allow that depth and the added weight when planning cabinet space beside the IE3400 base switch.
  • How many expansion modules can attach to an IE3400 base switch together with IEM-3400-8T?

    One module attaches to a base system. IEM-3400-8T adds 8 Gigabit copper ports and takes the system to 18 ports. A second expansion module cannot be added, so plan the eight ports as the single expansion step for the IE3400 base switch.
  • Does IEM-3400-8T provide PoE or PoE+ on its eight copper ports?

    No. IEM-3400-8T carries data-only Gigabit Ethernet RJ45 ports, and neither PoE, PoE+ nor 90-W PoE is supported. Connect externally powered devices such as PLCs, drives and HMIs. The module draws 12 W from the base switch, so the added ports serve devices with their own power supply.
