Cisco IEM-3300-8T Catalyst IE3300 Rugged 8-Port GE Copper Expansion Module - Cisco Refresh

The Cisco IEM-3300-8T (orderable as IEM-3300-8T=) is an 8-port Gigabit Ethernet copper expansion module for Cisco Catalyst IE3300 Rugged Series industrial switches. It adds eight 10/100/1000BASE-T RJ-45 downlink ports in a single-wide DIN rail form factor — expanding system capacity to 18 total ports on an IE3300 base unit (8 base downlinks + 8 expansion + 2 uplinks). Important: this is a non-PoE module — it does NOT deliver power to connected devices. Use the IEM-3300-8P instead if PoE output is required. This unit is Cisco Refresh — Cisco’s official factory-remanufactured program: fully tested and restored to original Cisco specifications.

Cisco IEM-3300-8T - Key Features & Benefits

• 8x Gigabit Copper Ports (10/100/1000BASE-T RJ-45): Adds eight line-rate downlink ports to a Cisco Catalyst IE3300 Rugged Series base switch. With an IE3300 base, total system capacity reaches 18 ports (8 base downlinks + 8 expansion + 2 uplinks); maximum ports vary by base switch model.
• Non-PoE Module — Data Only, No Power Output: This module does NOT supply PoE or PoE+ to connected devices. Intended for non-powered Ethernet endpoints — PLCs, HMIs, industrial PCs, and IP gateways. To power IP phones, cameras, or wireless APs through the expansion module, choose the IEM-3300-8P (8 ports of PoE/PoE+) instead.
• Hardened Industrial Design: Fanless, convection-cooled construction with vibration, shock, and electrical-surge tolerance built for manufacturing, utilities, and transportation. Operating range depends on enclosure: −40°C to +60°C sealed, −40°C to +70°C with 40 LFM vented airflow, −40°C to +75°C with 200 LFM fan or blower.
• Single-Wide DIN Rail — Powered by the Base Switch: Compact 6.0 × 2.6 × 5.3 in (0.91 kg) module slides into the IE3300 expansion bay and adds just 2 inches to system width. Draws roughly 6W from the base switch — no separate power adapter or input required.
• Cisco IOS XE Auto-Detect — No Module License Needed: Auto-detected by the IE3300 base switch — no separate configuration or firmware load. The module does not require its own software license; it operates under the base switch’s existing Network Essentials or Network Advantage license. Managed through Cisco IOS XE, WebUI, Cisco Catalyst Center, NETCONF, and RESTCONF.

Cisco IEM-3300-8T - Frequently Asked Questions (FAQ)

• Which switches is this expansion module designed for?
  Fully supported: Cisco Catalyst IE3300 Rugged Series base switches — IE-3300-8T2S, IE-3300-8P2S, IE-3300-8T2X, and IE-3300-8U2X. Limited support: It also installs on IE3400 base switches, but pairing this IE3300 module with an IE3400 base disables advanced security features such as SGT/SGACL on the base switch. For full IE3400 feature support, use an IEM-3400-series module instead.
• Does this module deliver PoE to connected devices?
  No — this is a non-PoE, data-only module. It carries network traffic only on all 8 ports. If you need to power IP phones, cameras, wireless APs, or other PoE-dependent endpoints through the expansion module, choose the IEM-3300-8P (8 ports of PoE/PoE+) instead. The 8T and 8P are mechanically and physically interchangeable on the IE3300 base — the only difference is power output.
• What is “Cisco Refresh” and what’s included in the box?
  Cisco Refresh is Cisco’s official factory-remanufactured program: units are fully tested and restored to original Cisco specifications directly by Cisco — not third-party refurbished. Included: module only. No power adapter, patch cables, or separate accessories ship with the unit, since the module is powered by the IE3300 base switch and uses the base’s existing DIN rail mount.
