IEM-3300-16P - Cisco IE3300 Rugged 16 Port GE PoE+ Expansion Module

Cisco IEM-3300-16P — IE3300 Rugged 16-Port GE PoE+ Expansion Module

What it is

IEM-3300-16P is a Cisco Industrial Ethernet 3300 Series rugged expansion module that adds 16 × Gigabit Ethernet (GE) PoE+ ports to a compatible Cisco IE-3300 chassis.
It delivers expanded powered connectivity in a hardened industrial form factor — ideal for edge sites that need to power devices like cameras, wireless access points, and industrial IoT gear in harsh environments.

Why buyers pick IEM-3300-16P (plain English)

High-density powered access
Provides 16 GE access ports that support Power over Ethernet Plus (PoE+), powering devices directly without separate injectors or local power.

Industrial-grade rugged design
Built for extended temperature ranges, vibration, dust, and electrical noise — perfect for factories, transportation hubs, utilities, and outdoor enclosures.

Seamless Cisco IOS management
Configured and managed with Cisco IOS just like the rest of the IE-3300 platform, giving consistent CLI, SNMP, NETCONF, and automation support.

Flexible deployment expansion
Modular form factor lets you add powered ports in the field, expanding access without forklift upgrades to new hardware.

Robust edge platform combo
Pairs with uplink and fiber modules for a complete industrial edge solution that’s both rugged and powerful.

Use case
Powering and connecting Ethernet devices at the industrial edge (cameras, APs, sensors, VoIP, etc.)

Where it fits (and when to choose something else)

Perfect for:

• Industrial and outdoor environments needing high-density powered ports

• Sites with many PoE devices (CCTV, APs, sensors) requiring centralized power

• Rugged edge applications with extended temperature and vibration requirements

• Expanding port count on IE-3300 platforms without replacing the base chassis

Choose something else if:

• You need fiber uplinks or extended reach → use SFP fiber modules (e.g., IEM-3300-8S)

• You need a mix of copper + fiber interfaces → combo modules like IEM-3300-6T2S

• You need higher-speed ports (>1G) → higher-speed industrial module options if supported

• You don’t need PoE → use non-powered expansion modules (e.g., IEM-3300-16T)

TL;DR

IEM-3300-16P is Cisco’s rugged 16-port GE PoE+ expansion module for the IE3300 Series:
a high-density powered Ethernet expansion option that delivers industrial-grade PoE+ connectivity at the network edge, ideal for powering devices in harsh environments.
