IE-3000-4TC Description

The IE-3000-4TC is a Cisco Industrial Ethernet 3000 Series Layer 2 switch for DIN-rail control cabinets on factory and process floors. The switch has four 10/100 ports, two dual-purpose Gigabit uplinks, a 16 Gbps switching fabric and 6.5 Mpps of forwarding, and it runs from an 18 to 60 VDC feed. Each uplink uses either its copper port or its SFP port at one time, and the installed LAN Base image provides Layer 2 features only.

Key Features

Dual-Purpose Gigabit Uplinks

Each of the two uplinks offers a 10/100/1000 copper port and an SFP port, and one of the two is active at a time. The cabling plan therefore decides copper or fiber for each uplink.

Expansion Modules For More Ports

Up to two IE 3000 expansion modules add ports. Two IEM-3000-8TM= copper modules bring the switch to 20 Fast Ethernet ports, and fiber, SFP and PoE modules are also available.

Fanless DIN-Rail Mounting

Convection cooling and an operating range of -40C to +75C suit sealed control panels. DIN rail, wall and 19 in rack mounting are supported.

Application Scenarios

Compact Machine Cell

In a small machine or process cell, the switch links four PLCs, drives or HMIs on its 10/100 ports and sends their traffic upstream on a Gigabit uplink.

Roadside Or Substation Cabinet

Mounted on DIN rail in a roadside traffic cabinet or substation panel, the switch runs fanless from an 18 to 60 VDC feed across -40C to +75C.

Fiber Handoff From The Line

At the edge of a production line, one SFP uplink can carry fiber to the plant backbone while the other stays on copper toward a local aggregation switch.

IE-3000-4TC and IE-3000-8TC use the same chassis, two dual-purpose uplinks and LAN Base image, but IE-3000-4TC has four 10/100 access ports where IE-3000-8TC has eight, which matters when a cabinet needs more than four drops before any expansion module. Sites that need the Layer 3 IP Services image order IE-3000-4TC-E, because the image is fixed by PID. Added ports come from IEM-3000-8TM= copper modules, and IE-3000-4TC takes up to two for 20 Fast Ethernet ports. IE-2000-8TC-G-B has eight ports and takes no expansion modules, but it accepts 9.6-60 VDC against 18-60 VDC here and is 3.6 in wide.

Ordering Checklist

  • Expansion modules: Choose up to two of IEM-3000-8TM=, IEM-3000-8FM=, IEM-3000-4SM=, IEM-3000-8SM=, IEM-3000-4PC= or IEM-3000-4PC-4TC=. Two IEM-3000-8SM= together are not supported because of power limits, and a module cannot run on its own.
  • PoE module power: Provide an external 44-57 VDC (PoE) or 50-57 VDC (PoE+) source such as PWR-IE65W-PC-DC= or PWR-IE65W-PC-AC=. IEM-3000-4PC= and IEM-3000-4PC-4TC= do not take PoE power from the switch.
  • AC power module: Order PWR-IE50W-AC= (screw terminal) or PWR-IE50W-AC-IEC= (IEC plug), 24 VDC output. The switch itself takes 18-60 VDC, so an AC site needs a power module.
  • AC power cord: Add a cord with the local plug and a C13 connector for PWR-IE50W-AC-IEC=. The module is supplied without a power cord.
  • Rack mounting: Add STK-RACKMNT-2955= to convert the DIN rail mount for a 19 in rack. Without the kit the switch mounts only on DIN rail or wall.

Questions & Answers

  • What operating temperature does IE-3000-4TC support?

    IE-3000-4TC operates from -40C to +75C. The switch uses convection cooling with no fan, and operating humidity can range from 10% to 95% non-condensing, which suits a DIN-rail cabinet without forced airflow.
  • What input voltage does IE-3000-4TC accept?

    IE-3000-4TC accepts a DC input range of 18-60 VDC. A 24 VDC feed, such as the output of PWR-IE50W-AC=, falls inside that range, while an AC site needs a power module before the switch can be powered.
  • How much power do the expansion modules add to IE-3000-4TC?

    Per the Cisco IE 3000 hardware installation guide, IEM-3000-8TM= draws 2.8 W, IEM-3000-8FM= 10.1 W and IEM-3000-8SM= 12.2 W at most, and the PoE modules draw less than that before PoE power. Add the module draw to the 15.1 W switch figure when sizing the DC feed.
  • Does IE-3000-4TC need a power module on an AC feed?

    Yes. IE-3000-4TC takes 18-60 VDC, so an AC site needs a power module. Order PWR-IE50W-AC= with screw terminals or PWR-IE50W-AC-IEC= with an IEC plug, both with 24 VDC output. PWR-IE50W-AC-IEC= ships without a power cord, so add a cord with a C13 connector.
  • Does IE-3000-4TC accept two IEM-3000-8SM= modules at the same time?

    No. Two IEM-3000-8SM= modules together are not supported on IE-3000-4TC because of power limits. A module also cannot run on its own. Choose up to two modules from IEM-3000-8TM=, IEM-3000-8FM=, IEM-3000-4SM=, IEM-3000-4PC= or IEM-3000-4PC-4TC= in supported combinations.
  • Where does the PoE power come from for IEM-3000-4PC= modules fitted to IE-3000-4TC?

    No. IEM-3000-4PC= and IEM-3000-4PC-4TC= do not take PoE power from IE-3000-4TC. Provide an external source for them instead. Use 44-57 VDC for PoE or 50-57 VDC for PoE+, such as PWR-IE65W-PC-DC= or PWR-IE65W-PC-AC=.
