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

Cisco Catalyst IE3300 Rugged Series 8-port Gigabit Ethernet copper expansion module for industrial switch port scaling.

The Cisco IEM-3300-8T is a hardware expansion module engineered for the Cisco Catalyst IE3300 Rugged Series (and compatible IE3400 base switches). It adds eight additional 10/100/1000 Mbps copper RJ-45 Ethernet ports to a base switch chassis, increasing overall port density up to 18 or 26 ports depending on the base model, without requiring replacement of the core switch. Built to the same ruggedized standards as the IE3300 family, it is DIN-rail mountable, operates across a wide temperature range, and integrates directly into the base switch's power and management architecture. It is intended for industrial, extended-enterprise, and harsh-environment deployments such as factory automation, transportation, utilities, and smart city infrastructure where reliable, scalable Gigabit Ethernet connectivity is required.

Q: What is the Cisco IEM-3300-8T used for?

A: It is an expansion module that adds eight Gigabit Ethernet copper ports to a compatible Cisco Catalyst IE3300 (or IE3400) Rugged Series base switch, increasing port density for industrial networks.

Q: Which switches are compatible with the IEM-3300-8T?

A: It is designed for Cisco Catalyst IE-3300 Rugged Series base switches and is also compatible with the IE3400 Rugged Series, per Cisco and distributor documentation.

Q: Does the IEM-3300-8T support Power over Ethernet (PoE)?

A: No, the IEM-3300-8T is a non-PoE copper module; users needing PoE should look at the IEM-3300-8P variant.

Q: Can the IEM-3300-8T be hot-swapped into a running switch?

A: Yes, third-party documentation indicates it supports installation without powering down the host switch, though some installation guides recommend powering down first for safety.

Q: What is the operating temperature range of the IEM-3300-8T?

A: According to Cisco and distributor sources, it operates from -40°C to +70°C in a vented enclosure, and -40°C to +60°C in a sealed enclosure.
