IEM-3400-8T is an expansion module, not a standalone switch. Eight non-PoE Gigabit copper ports extend a compatible Catalyst IE3400 Rugged base switch. The module joins the host assembly on a DIN rail; management, software features, and uplink connectivity remain functions of the base switch.
IEM-3400-8T price for new stock is $2,390.85, a 38.6% saving from the Cisco list price of $3,893.00. IEM-3400-8T refurb price is $945.95. IEM-3400-8T is in stock and available for free next-day delivery. (terms applied)

12W module consumption must be included when sizing the complete assembly's power source. IEM-3400-8T uses its host's network license rather than carrying an independent software tier. Network Essentials and Network Advantage provide perpetual base licensing; optional DNA Essentials and DNA Advantage subscriptions offer 3-year, 5-year, and 7-year terms. Subscription purchases require separate consideration from the hardware module order.
Specify IEM-3400-8T in new sealed or certified refurbished condition, and identify the compatible host separately on the purchase order. Certified refurbished modules are inspected and bench-tested, with every copper port checked for a link at rated speed in a compatible assembly. ORM's new condition carries up to a 3-year extended warranty; certified refurbished carries up to 1 year, with 30-day returns on every condition, terms apply. For enterprise and volume orders, state quantities and the required condition; PO accepted, Net-30 for government, and RMA with advance replacement are available across UK, EU, US, and MEA regional stock/RMA operations.

When adding connections inside an existing industrial cabinet, assess the assembled equipment rather than the module alone. Installation requires vertical orientation and 50.8 mm clearance above, below, in front, and at the exposed side. Confirm enclosure space and cable access before specifying the order.
When staging an expansion before installation, prepare the host configuration and a port-by-port connection plan. Copper Ethernet connections have a 100 m maximum cable distance. Review endpoint locations, patching, and cable routes before ordering the module and scheduling the work.
PoE-powered endpoint connections
The module provides data connections without PoE. IEM-3400-8P= supplies powered copper ports and requires a compatible PoE-capable base switch.
Fiber connections on the module
The copper-only module has no SFP cages. IEM-3400-8S= provides eight Gigabit SFP interfaces instead.
