IEM-3300-16T is a fanless industrial expansion module with 16 Gigabit Ethernet copper ports, not a standalone switch. The module extends a compatible Catalyst IE3300 Rugged or Catalyst IE3400 Rugged base switch and depends on that host for operation and management. Its non-PoE interfaces connect separately powered equipment; attaching the module to a PoE-capable host does not add endpoint power to these ports. The DIN rail assembly adds copper connectivity without adding independent uplinks. IEM-3300-16P= is the corresponding powered-port alternative, with PoE/PoE+ interfaces and a requirement for a PoE-capable base switch.
IEM-3300-16T price for new stock is $2,323.65, a 43.7% saving from the Cisco list price of $4,129.00. IEM-3300-16T refurb price is $1,312.50. IEM-3300-16T 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. The module measures 152 mm high, 91 mm wide and 135 mm deep, with a weight of 1.2 kg, so cabinet drawings must allow for the attached hardware rather than the base switch alone. IEM-3300-16T supports copper-port autonegotiation and auto-MDIX through the host, with attached devices limited to a 100 m copper connection. Configuration remains on the base switch: the module does not create another independently administered switch. Its hardware expansion role does not provide a separate routing license, management console or additional fiber interface.
IEM-3300-16T is available new sealed or certified refurbished; refurbished modules are inspected and bench-tested, with every copper port checked for linking at its rated speed. Specify the condition and quantity on the purchase order, together with the host model for compatibility confirmation. ORM coverage is 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, and Cisco's five-year limited hardware warranty remains separate. PO accepted, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US and MEA support enterprise and volume orders.

An existing compatible industrial switch needs more connections for separately powered equipment, but replacing the complete assembly is not part of the project. The expansion supports a 26-port system configuration. Specify the required installed system configuration and reconcile the endpoint schedule with the base switch before issuing the PO.
A cabinet retrofit must accommodate the expanded assembly without obstructing convection cooling or service access. Installation requires 50.8 mm clearance above, below, in front and on the exposed side. Check the enclosure layout, cable routing and available mounting space before specifying the assembly on the purchase order.
An independently operating industrial switch
IEM-3300-16T requires a compatible base switch and cannot operate independently. A module-only order does not supply a complete industrial switching system.
PoE power on added ports
IEM-3300-16T supplies no endpoint power. IEM-3300-16P= adds PoE/PoE+ copper ports, but requires a PoE-capable base switch and appropriate system power provisioning.
Fiber connections on the expansion
IEM-3300-16T has copper interfaces only. IEM-3300-14T2S= provides two Gigabit SFP interfaces alongside 14 copper ports, reducing the added copper-port count.

Efficient and durable copper expansion.
IEM-3300-16T identifies expansion-module hardware: IEM denotes the module, 3300 identifies the Catalyst IE3300 family, 16 gives the port count, and T corresponds to copper Ethernet connectivity. IEM-3300-16T= is another ordering form for the same configuration, rather than a standalone switch with its own uplinks.
No, IEM-3300-16T requires a compatible Catalyst IE3300 or Catalyst IE3400 base switch. The module attaches directly to the host assembly rather than operating as an independent Ethernet switch. Include the base switch in a new-system order, or confirm the existing host before ordering an expansion.
IEM-3300-16T is managed through its host switch rather than a separate module interface. Host options include Web UI, CLI through serial or USB console, SSH or Telnet, SNMP, CIP tools, STEP 7, TIA Portal, NETCONF, RESTCONF, and optional Cisco Catalyst Center. Host software and entitlement govern availability.
No, IEM-3300-16T cannot be attached while the host switch is energized; expansion modules are not hot-swappable. Remove power before installation and attach the module before mounting the combined assembly. Treat module replacement as planned physical maintenance rather than an online port-expansion operation.
IEM-3300-16T does not select a Network Essentials or Network Advantage tier; the host switch determines software features. Catalyst IE3300 offers perpetual Network Essentials and Network Advantage licenses, with optional Catalyst Center Essentials or Advantage subscriptions starting at three years. Catalyst Center Advantage requires Network Advantage on the host.
Cisco has not announced an end-of-sale date for Catalyst IE3300 Rugged. IEM-3300-16T is an expansion module in that family. Retirement dates for individual host software releases are separate from hardware retirement, so software maintenance planning should remain distinct from a decision to replace this module.
ORM Systems offers IEM-3300-16T new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate five-year limited hardware warranty is manufacturer coverage, not an additional ORM warranty.
IEM-3300-16T provides non-PoE copper ports, whereas IEM-3300-16P= provides PoE/PoE+ copper ports; both add 16 interfaces. The powered module requires a PoE-capable base switch. Choose IEM-3300-16T for separately powered equipment and IEM-3300-16P= when the added connections must also power compatible endpoints.
IEM-3300-16T adds 16 copper Gigabit Ethernet ports, whereas IEM-3300-8T= adds eight. Both are non-PoE expansion modules for a compatible host. Select IEM-3300-16T when the endpoint schedule requires the higher added port count, or IEM-3300-8T= when eight additional copper connections meet the requirement.
IEM-3300-16T adds 16 copper Gigabit Ethernet ports, while IEM-3300-14T2S= adds 14 copper ports and two Gigabit SFP interfaces. The difference is the connection mix, not an independent switching role. Choose IEM-3300-16T for all-copper expansion or IEM-3300-14T2S= when the expansion must include fiber connections.
IEM-3300-16T consumes 12W, measured with the non-PoE system at 12V. That figure covers the expansion module rather than the complete switching assembly. Include the host's own consumption when sizing the system power source, and do not treat module consumption as an available endpoint power budget.
Catalyst IE3300 Rugged supports -40°C to 60°C in a sealed enclosure, with higher limits dependent on airflow. A vented enclosure permits 70°C with 0.2032 m/s airflow; a fan-assisted enclosure permits 75°C with 1.016 m/s airflow. Select the operating limit against the actual enclosure and cooling arrangement.
