Cisco IEM-3300-8P — IE3300 Rugged 8-Port GE PoE+ Expansion Module
What it is
IEM-3300-8P is a Cisco Industrial Ethernet 3300 Series ruggedized expansion module that adds 8 × Gigabit Ethernet (GE) PoE+ ports to a compatible Cisco IE-3300 chassis.
It provides powered Ethernet at industrial strength, letting you expand port count and deliver Power over Ethernet Plus (PoE+) for devices in harsh environments like factories, outdoor enclosures, transit, and utilities.
Why buyers pick IEM-3300-8P (plain English)
PoE+ power for edge devices
Delivers PoE+ (802.3at) power on all 8 GE ports to support IP cameras, industrial wireless APs, VoIP phones, sensors, and automation devices — without separate injectors.
Rugged industrial design
Designed for extended temperatures, vibration, dust, and electromagnetic noise typical of industrial and outdoor applications.
Modular and expandable
Installs as an expansion module into the IE-3300 base switch, letting you add PoE+ port density without replacing the whole device.
Consistent Cisco IOS experience
Managed with the same Cisco IOS feature set used across the Industrial Ethernet portfolio — familiar CLI, SNMP, NETCONF, and automation capabilities.
Flexible deployment
Great for expanding both connectivity and power where fiber or copper aggregation uplinks are needed at the edge.

Use case
Industrial edge switching with powered devices
Where it fits (and when to choose something else)
Perfect for:
-
Industrial and outdoor environments needing powered edge ports
-
Deployments powering IP cameras, industrial APs, VoIP devices, sensors
-
Expanding port count on IE-3300 platforms
-
Rugged sites with extended temperature and vibration requirements
Choose something else if:
-
You need fiber extensions → SFP fiber expansion modules (e.g., IEM-3300-8S)
-
You need multigigabit speeds → higher-speed industrial modules if supported
-
You’re in a non-industrial enterprise environment → Catalyst/enterprise access switches
TL;DR
IEM-3300-8P is Cisco’s rugged industrial 8-port Gigabit PoE+ expansion module for the IE3300 Series:
a modular way to add powered GE ports in harsh environments for cameras, APs, sensors, and other powered edge devices.
