IEM-3300-16P is a fanless industrial expansion module that adds sixteen Gigabit Ethernet copper ports with PoE/PoE+ to a compatible PoE base switch. The Catalyst IE3300 Rugged module forms part of a DIN-rail assembly rather than operating as a standalone switch. Its powered connections serve endpoints such as cameras, phones and wireless access points, while uplinks remain on the host. For installations with independently powered endpoints, IEM-3300-16T= provides sixteen copper Gigabit ports without PoE. The distinction is important when ordering an expansion module rather than a complete switch.
IEM-3300-16P price for new stock is $7,551.60, a 19.3% saving from the Cisco list price of $9,356.00. IEM-3300-16P refurb price is $4,321.80. IEM-3300-16P is in stock and available for free next-day delivery. (terms applied)

21W of module electronics consumption, measured at 54V, must be included when sizing system power, separately from power delivered to endpoints. IEM-3300-16P depends on the attached base for operating software, forwarding, routing and uplinks; adding the module does not create another independently configured switch. Host management includes WebUI, console CLI, SSH, Telnet and SNMP, with industrial integration through CIP tools and PROFINET management. The 16-port PoE+ expansion module attaches through the host’s side connection. A compatible PoE base is required: a non-PoE base cannot accept this powered expansion option.
ORM Systems supplies IEM-3300-16P new sealed or certified refurbished; refurbished modules are inspected and bench-tested, with every port checked at rated speed and PoE output verified under load on every powered port. Specify condition, quantity, compatible host and power requirements on the purchase order, including separately required system components. ORM coverage is up to a three-year extended warranty on new orders or up to one year on certified refurbished orders, with 30-day returns on every condition; terms apply. For enterprise and volume orders, POs are accepted, government buyers have Net-30 terms, and RMA with advance replacement is available across UK, EU, US and MEA operations.

When an installed PoE base needs additional endpoint connections, the expanded assembly can reach 26 total system ports. Keep the host’s uplinks assigned to distribution and plan the additional endpoint cabling before ordering. Confirm the exact host configuration, endpoint requirements and available cabinet space on the purchase order.
When preparing an assembly for a scheduled installation window, attach the module before DIN-rail mounting and keep the host de-energized during attachment. Reserve 50.8 mm around the top, bottom, exposed side and front, and provide a separate module EMC ground. Include the required grounding materials in the purchase order.
Standalone switching without a base
The module cannot operate independently. IE-3300-8P2S-E is a standalone base with eight Gigabit PoE+ access ports and two Gigabit SFP uplinks, rather than sixteen expansion ports.
Fiber connections on the expansion module
The module provides copper connections only. IEM-3300-14T2S= instead supplies fourteen copper ports and two Gigabit SFP ports, but does not provide PoE.
Attachment while the host remains powered
The host must be de-energized before module attachment. Installation therefore requires a planned power interruption; attaching the module to an energized switch is prohibited.
SGT/SGACL enforcement on an IE3400 host
Pairing this module with a Catalyst IE3400 base prevents SGT/SGACL support. Avoid that combination when the host must retain those advanced security functions.

IEM-3300-16P identifies a Catalyst IE3300 expansion module with sixteen Gigabit copper PoE/PoE+ ports. IEM indicates the expansion-module role, 3300 identifies the family, 16 gives the port count, and P identifies powered copper interfaces. The spare ordering form is IEM-3300-16P=, rather than a complete standalone switch.
IEM-3300-16P is managed through its host using WebUI, console CLI, SSH, Telnet, SNMP or optional Cisco Catalyst Center. Industrial management includes CIP tools and STEP 7 or TIA Portal through PROFINET. NETCONF and RESTCONF support automation; the expansion module does not establish a separate management plane.
Cisco has not announced an end-of-sale date for Catalyst IE3300 Rugged. IEM-3300-16P belongs to that hardware family. Individual software releases and accessories have separate retirement milestones, so distinguish those dates from hardware retirement when defining the host software baseline, service requirements and expected operating period.
ORM Systems offers IEM-3300-16P new sealed or certified refurbished, with up to a three-year extended warranty on new orders and up to one year on refurbished orders. Cisco’s separate hardware warranty is five years limited. Every condition has 30-day returns; terms apply.
IEM-3300-16P has no independent network license tier; its host uses perpetual Network Essentials or Network Advantage. Optional Cisco Catalyst Center Essentials and Advantage subscriptions have three-, five- or seven-year terms. Catalyst Center Advantage requires Network Advantage on the host, and those management subscriptions do not include perpetual network features.
IEM-3300-16P= is a migration option for the discontinued IEM-3000-4PC= expansion module, which reached end of sale on June 30, 2020. Cisco support for the older module ended June 30, 2025. Migration also requires the newer switch family; the replacement module is not an IE3000 attachment.
IEM-3300-16P provides PoE/PoE+ on sixteen copper Gigabit ports, while IEM-3300-16T= provides sixteen non-PoE copper Gigabit ports. The powered module requires a PoE-capable host. Choose the powered version for endpoints supplied over Ethernet; the non-PoE option suits devices that receive power independently.
IEM-3300-16P adds sixteen Gigabit PoE/PoE+ copper ports, whereas IEM-3300-8P= adds eight. Both are expansion modules for compatible PoE base switches, rather than independent switches. Select sixteen ports for higher endpoint counts, or eight where the additional powered connections are not required.
IEM-3300-16P supplies sixteen copper ports, while IEM-3300-14T2S= supplies fourteen copper ports and two Gigabit SFP ports. The copper-only module does not add optical connections. Choose IEM-3300-16P when all additional endpoint connections are copper; choose IEM-3300-14T2S= when the expansion must include fiber connections.
IEM-3300-16P requires a PoE-capable base, including IE-3300-8P2S-E or IE-3300-8U2X-E. Non-PoE bases cannot accept this powered expansion module. The host supplies the uplinks, operating software and system power, so match the module to the exact host configuration and power arrangement before specifying the complete assembly.
