Cisco IEM-3300-16T IE3300 16-Port GE Copper Non-PoE Expansion Module Refresh

The Cisco IEM-3300-16T is a 16-port Gigabit Ethernet copper expansion module for the Cisco Catalyst IE3300 Rugged Series industrial switch platform. It adds 16x 10/100/1000BASE-T RJ-45 ports to a compatible IE3300 base unit for high-density industrial connectivity. Built for harsh environments with a fanless DIN-rail design and a −40°C to +70°C operating range. Shipped as Cisco Refresh (IEM-3300-16T-RF) — genuine Cisco-remanufactured hardware, identical in performance to new units.

✓ Compatible With: Cisco Catalyst IE3300 Rugged Series base switches — IE-3300-8T2S, IE-3300-8P2S, IE-3300-8U2X, and other IE3300 variants. Requires an IE3300 base unit to operate.

✓ Best For: Factory automation, SCADA networks, intelligent transportation (ITS), utility substations, smart grid, and any industrial deployment needing high-density Gigabit copper connectivity to PLCs, IP cameras, sensors, and controllers.

⚠ Important — Non-PoE Data Only: This module does not supply PoE power. Connected devices must be self-powered, or choose IEM-3300-16P (16x PoE/PoE+) if you need to power IP phones, cameras, or wireless APs over the cable.

Cisco IEM-3300-16T-RF - Key Features & Benefits

• Fits Cisco Catalyst IE3300 Base Switches: Drop-in expansion module for the Cisco Catalyst IE3300 Rugged Series — compatible with IE-3300-8T2S, IE-3300-8P2S, IE-3300-8U2X, and other IE3300 base variants. Requires an IE3300 base unit — not a standalone switch.
• Non-PoE / Data Only: The 16T variant delivers data only — it does not supply PoE to downlink devices. If you need PoE for IP phones, cameras, or APs, choose IEM-3300-16P or IEM-3300-16P4S instead.
• 16x Gigabit Copper Downlinks: Provides 16x 10/100/1000BASE-T RJ-45 ports for high-density connection of PLCs, IP cameras, controllers, and industrial sensors on the IE3300 platform.
• Hot-Swappable Modular Design: Hot-swappable module installs on the IE3300 base without service interruption — scale port density in the field as network demand grows.
• Rugged & DIN-Rail Ready: Fanless design rated for −40°C to +70°C and IP30 ingress; compact 6" × 3.4" × 5.3" enclosure mounts on DIN rail alongside the base unit.
• Managed via Host IE3300 Switch: VLAN, QoS, ACLs, CIP, PROFINET, IEC 61850, PTP, Resilient Ethernet Protocol (REP), and security features are configured on the base switch and applied across all module ports.

Cisco IEM-3300-16T-RF - Frequently Asked Questions (FAQ)

• What is the difference between IEM-3300-16T and IEM-3300-16T-RF?
  Hardware is identical. IEM-3300-16T= is the new-condition Cisco SKU; IEM-3300-16T-RF is the Cisco Refresh SKU — Cisco-remanufactured, fully tested, and certified by Cisco Refresh to the same performance specification as new.
• Does this module support PoE?
  No. The 16T variant is non-PoE (data only). If PoE downlinks are required, use the IEM-3300-16P (16x PoE/PoE+) or IEM-3300-16P4S (16x PoE with SFP) instead.
• Does it work standalone or need a base switch?
  It is an expansion module and must be installed on a Cisco Catalyst IE3300 Rugged Series base switch (e.g., IE-3300-8T2S, IE-3300-8P2S). It cannot operate independently and does not include a base unit.
