IEM-3000-4SM is a four-port 100Mbps SFP expansion module for Cisco Industrial Ethernet 3000 switches, not a standalone Ethernet switch. The module adds Fast Ethernet connections to an existing industrial switching assembly and relies on the host for management and forwarding control. Its fanless, DIN-rail construction accommodates installation alongside the base switch in a control cabinet. The four-port SFP expansion module accepts removable transceivers rather than providing fixed optical interfaces, allowing the optical connection to match the installed fiber. It supplies no PoE output and does not add dedicated Gigabit uplinks or an independent routing image.
IEM-3000-4SM price for new stock is $863.10, a 51.1% saving from the Cisco list price of $1,764.00. IEM-3000-4SM refurb price is $225.75. IEM-3000-4SM is in stock and available for free next-day delivery. (terms applied)

7.6W maximum module consumption must be included in the switching assembly's power allowance. IEM-3000-4SM measures 147 mm high, 89 mm wide and 112 mm deep, so cabinet layouts need room for the expansion body beside the host; module weight is 1.1 kg. Operating limits depend on the enclosure: -40°C to 60°C in a sealed enclosure or -40°C to 70°C in a vented enclosure. Safety and EMC coverage includes UL 60950-1, IEC 60950-1, FCC Part 15 Class A and EN 55022. The host supplies the switching resources; the expansion module does not introduce a separate management processor or independently licensed software image.
ORM Systems offers IEM-3000-4SM new sealed or certified refurbished; refurbished modules are inspected and bench-tested for optics bay recognition and rated-speed links on every port. Specify condition, quantity and any required optics on the purchase order. ORM warranties are up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco service and warranty eligibility ended December 31, 2025. Enterprise and volume orders can use PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA covering the UK, EU, US and MEA.

Maintenance teams replacing an installed expansion module must shut down the host because expansion modules are not hot-swappable. A spare-module order therefore needs an approved interruption and a host restart check in the work scope. Confirm the replacement quantity and shutdown authorization before issuing the purchase order.
Cabinets receiving an additional side-mounted module need clearance beyond the hardware dimensions: 105 mm above and below, 90 mm at the exposed side, and 65 mm at the front. Retain access to indicators and fiber connectors; check the assembled layout before specifying the cabinet and module quantities.
Standalone Ethernet switching
The expansion module cannot operate independently and requires a compatible IE 3000 host. An order containing only this module does not provide a functioning standalone switch.
Gigabit fiber access links
The SFP interfaces operate at 100Mbps and do not support 1Gbps. Gigabit connectivity on the host does not increase the speed of these expansion ports.
Active Cisco service coverage
Cisco service ended after December 31, 2025. No direct replacement module was designated, so this discontinued component cannot satisfy a requirement for active manufacturer support.

Cisco IEM-3000-4SM identifies an Industrial Ethernet 3000 expansion module: IEM-3000 identifies the expansion family, 4 denotes four ports, and SM identifies the SFP configuration. The corresponding ordering form is IEM-3000-4SM=, providing 100Mbps SFP interfaces rather than Gigabit Ethernet expansion ports.
IEM-3000-4SM is managed through its IE 3000 host. Host paths include Device Manager over HTTPS, console or Telnet CLI, SSH with a cryptographic image, SNMP tools, Cisco Network Assistant, CiscoWorks, Cisco Prime LMS, Cisco DNA Center, PROFINET tools and CIP-based tools; the module has no independent management interface.
IEM-3000-4SM is discontinued: Cisco sales ended December 29, 2020, and its last date of support was December 31, 2025. Cisco service has ended, and no direct replacement module was designated. Existing installations therefore depend on retained hardware and reseller support rather than active Cisco product support.
ORM Systems offers IEM-3000-4SM new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco's original five-year limited warranty and service eligibility ended December 31, 2025.
IEM-3000-4SM supports IE-3000-4TC, IE-3000-8TC, IE-3000-4TC-E and IE-3000-8TC-E hosts. These hosts are discontinued. The module attaches through the host's expansion interface and cannot operate independently; compatibility depends on the base-switch model and supported module combination, rather than an Ethernet connection between standalone switches.
No, IEM-3000-4SM SFP ports operate at 100Mbps and do not support 1Gbps. The SFP form factor does not make these interfaces Gigabit-capable. Gigabit uplinks on the IE 3000 host remain separate interfaces and do not increase the speed of the module's expansion ports.
Cisco IOS 15.0(2)EY or later on the host is required for IEM-3000-4SM. The release requirement belongs to the IE 3000 base switch. The expansion module adds physical interfaces and does not replace the host's operating system or independently change its software feature set.
No, the IE 3000 SFP expansion module is not hot-swappable, and host power must be turned off before adding or removing it. This restriction concerns the expansion body and its host connection, rather than the separate procedures for installing or removing SFP transceivers.
IEM-3000-4SM has a maximum module power consumption of 7.6W. That figure describes the expansion module, not the complete IE 3000 switching assembly. The base switch and any other attached components have their own power requirements, which remain separate from this module's consumption.
IEM-3000-4SM provides four 100Mbps SFP ports, while IEM-3000-8SM= provides eight. Both are discontinued expansion modules rather than standalone switches. The four-port model matches maintenance requirements for four SFP connections; the eight-port model corresponds to legacy assemblies requiring the higher SFP port density.
IEM-3000-4SM supplies four 100Mbps SFP interfaces without PoE, while IEM-3000-4PC= supplies four 10/100 copper PoE/PoE+ interfaces. Both are discontinued. The SFP model serves legacy fiber expansion requirements; the copper model corresponds to maintenance configurations requiring powered Ethernet endpoints instead of optical connections.
The four-port SFP expansion module uses Fast Ethernet optics such as GLC-FE-100FX-RGD= for multimode fiber links reaching 2 km and GLC-FE-100LX-RGD for single-mode links reaching 10 km. Optical interface selection determines fiber type and reach; the module's SFP ports remain limited to 100Mbps.
