IEM-3000-8TM Description

The IEM-3000-8TM is a Cisco Industrial Ethernet 3000 Series expansion module that adds eight 10/100 TX copper ports to IE-3000-4TC and IE-3000-8TC switches. The module draws up to 2.8 W and measures 3.5 x 5.8 x 4.4 in., so it mounts beside the host switch on a DIN rail. The module cannot run on its own and is not hot-swappable, so the host switch must be powered off to add or remove it.

Application Scenarios

Control Cabinet Port Expansion

A machine control cabinet built on an IE-3000-4TC can add eight Fast Ethernet ports for PLCs, HMIs and sensors by attaching the module. One module takes the switch from 4 to 12 Fast Ethernet ports.

Copper Growth On An Existing Line

A production line already running an IE-3000-8TC can add a second copper expansion module as more devices arrive. Two IEM-3000-8TM modules take the host to 24 Fast Ethernet ports.

IEM-3000-8TM adds eight 10/100BASE-T copper ports at 2.8W, while IEM-3000-8FM adds eight 100BASE-FX fiber ports at 10.1W; all three modules in this group are eight-port, cannot run standalone and are not hot-swappable. Fiber runs to field devices call for IEM-3000-8FM, and 100M SFP optics chosen per site move the order to IEM-3000-8SM at 12.2W. Because of power limits an IE 3000 switch cannot take two IEM-3000-8SM modules, so a two-module build that needs SFP ports pairs IEM-3000-8SM with a copper or fiber module. Copper-only builds reach 12 Fast Ethernet ports on IE-3000-4TC and 16 on IE-3000-8TC with one IEM-3000-8TM.

Ordering Checklist

  • IE 3000 hosts: Pair the module with IE-3000-4TC and IE-3000-8TC, or the IP Services images IE-3000-4TC-E and IE-3000-8TC-E. The module is an expansion for these IE 3000 switches only and cannot run on its own.

Questions & Answers

  • Which host switches take IEM-3000-8TM?

    IEM-3000-8TM installs on IE-3000-4TC and IE-3000-8TC hosts, including the IP Services images IE-3000-4TC-E and IE-3000-8TC-E. A host takes one or two expansion modules in supported combinations, and the first module ports appear as Fast Ethernet2/1 through 2/8 and a second as Fast Ethernet3/1 through 3/8.
  • How much does IEM-3000-8TM add to the maximum power draw of an IE 3000 host switch?

    The module adds up to 2.8 W. The host switch draws up to 15.1 W for IE-3000-4TC and up to 15.7 W for IE-3000-8TC, per the IE 3000 hardware installation guide. Add the module figure to the host figure when you size the DC power supply for the cabinet.
  • What MTBF and weight does Cisco list for IEM-3000-8TM?

    The data sheet gives IEM-3000-8TM an MTBF of 926,999 (hours) and a weight of 2.2 lb (1.0 kg). The hardware installation guide lists 2.05 lb (0.93 kg) instead. Use the higher weight when you plan DIN rail loading for the cabinet.
  • Which other IE 3000 expansion modules can share a host switch with IEM-3000-8TM?

    The installation guide lists IEM-3000-8TM in combination with IEM-3000-8FM, IEM-3000-4SM, IEM-3000-4PC and IEM-3000-4PC-4TC. The PoE modules need an external supply of 44 to 57 VDC for PoE or 50 to 57 VDC for PoE+, and they need Cisco IOS 15.0(2)EY2 or later.
  • Which host switches does IEM-3000-8TM install on?

    IEM-3000-8TM installs on IE-3000-4TC and IE-3000-8TC, and on their IP Services versions IE-3000-4TC-E and IE-3000-8TC-E. It cannot run on its own, and the host switch must be powered off before the module is added or removed from the DIN rail.
