Cisco IEM-3300-8S - Catalyst IE3300 Rugged 8-Port 1GE SFP Fiber Expansion Module - Refresh

The Cisco IEM-3300-8S is an 8-port industrial Ethernet expansion module for the Cisco Catalyst IE3300 Rugged Series. It adds 8x SFP (mini-GBIC) slots that accept 100/1000Mbps fiber SFP transceivers — expanding a compatible IE3300 base switch by up to 18 total system ports with long-distance fiber connectivity for industrial automation, intelligent transportation systems (ITS), substations, smart cities, energy, and rugged outdoor deployments. Hardened for harsh environments with a wide industrial operating temperature range, fanless convection cooling, IP30 ingress protection, and standard DIN-rail mounting, this module delivers enterprise-grade Gigabit Ethernet reach to manufacturing floors, transportation networks, oil and gas sites, and utility substations.

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

• 8-Port Gigabit SFP Fiber Expansion: Adds 8 SFP (mini-GBIC) slots that accept 100/1000Mbps fiber SFP transceivers — expands a compatible IE3300 base switch by up to 18 total system ports with extended-distance fiber reach.
• Industrial-Grade Wide Operating Temperature Range: Designed for harsh environments with fanless convection cooling and IP30 ingress protection; rated for −40°C to +60°C in sealed enclosures and up to +70°C / +75°C in vented or fan-equipped enclosures per Cisco airflow specifications — purpose-built for manufacturing, transportation, energy, mining, oil and gas, and outdoor industrial deployments.
• Supports Cisco-Approved Rugged Industrial SFPs: Compatible with Cisco industrial-rated SFP transceivers including GLC-SX-MM-RGD= (multimode), GLC-LX-SM-RGD= (single-mode), and GLC-ZX-SM-RGD= (long-haul single-mode) — plus additional Cisco-approved SFP options listed in the IE3300 Rugged Series datasheet. SFPs are sold separately.
• Plugs Into IE3300 GE and 10G Base Switches: Compatible with IE-3300-8T2S, IE-3300-8P2S, IE-3300-8T2X, and IE-3300-8U2X base systems — single-wide module adds just 2 inches to the chassis width and is powered directly from the base switch (no external power required).
• Compact DIN-Rail Mount Design: Measures 6 x 2.6 x 5.3 in (15.2 x 6.6 x 13.5 cm) at 2.0 lbs (0.91 kg) — mounts directly onto standard 35mm DIN rail in space-constrained industrial cabinets and control panels.

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

• Which base switches is this module compatible with?
  The IEM-3300-8S plugs into Cisco Catalyst IE3300 Rugged Series base systems including the IE-3300-8T2S, IE-3300-8P2S, IE-3300-8T2X, and IE-3300-8U2X. It is a single-wide module that adds 2 inches to the chassis width and is powered directly through the base switch — no separate power supply required.
• How is the IEM-3300-8S different from the IEM-3300-8T or IEM-3300-8P?
  The IEM-3300-8S provides 8x SFP (mini-GBIC) fiber ports for long-distance fiber connectivity. The IEM-3300-8T provides 8x copper RJ45 Gigabit ports (non-PoE), and the IEM-3300-8P provides 8x copper RJ45 ports with PoE/PoE+. Choose -8S for fiber, -8T for non-PoE copper, or -8P for PoE copper.
• Are SFP transceivers included with this module?
  No — SFPs are sold separately. The module supports Cisco-approved industrial-rated rugged SFPs such as GLC-SX-MM-RGD=, GLC-LX-SM-RGD=, and GLC-ZX-SM-RGD= for the widest industrial temperature operation. Refer to the Cisco Catalyst IE3300 Rugged Series datasheet for the full list of supported transceivers.
