IEM-3300-4MU Description
IEM-3300-4MU is a Cisco Catalyst IE3300 Rugged Series 1GE/2.5G 4PPoE copper expansion module for adding four RJ45 multigigabit PoE ports to supported industrial switch base systems. Cisco identifies the orderable PID as IEM-3300-4MU= and describes the module as a 4-port 2.5GE PoE/PoE+/4PPoE expansion option with up to 90W per port, used with IE3300 and IE3400 base-system deployments that need additional high-power copper access ports. The module supports a 14-port system total when installed, draws 20W, and follows the IE3x00 expansion-module boundary of one non-hot-swappable expansion module attached while the switch is powered down.

Application Scenarios
Use IEM-3300-4MU when an approved IE3300 or IE3400 PoE base system needs four additional copper links for endpoints that require both multigigabit access and 4PPoE Type 4 power.
This module fits retrofit cabinets where the endpoint mix has outgrown standard 1G PoE/PoE+ expansion but the design still needs a rugged DIN-rail IE3300-family expansion slot.
Keep the order tied to IE-3300-8P2S, IE-3300-8U2X, or IE-3400-8P2S base-system families because Cisco lists the 4MU module with PoE base systems and documents the PoE budget at system level.

- In an IEM-3300-4MU vs IEM-3300-8P comparison, the key difference is port class: IEM-3300-4MU provides four 1GE/2.5G 4PPoE ports while IEM-3300-8P provides eight 100/1000Mbps PoE/PoE+ ports.
- The IEM-3300-4MU difference from IEM-3300-16P is not only density; IEM-3300-16P raises the powered copper count to sixteen but does not provide the table-listed 1GE/2.5G Type 4 PoE port block.
- For IEM-3300-4MU vs IEM-3300-8T, the comparison should start with endpoint power because IEM-3300-8T is the eight-port data-only copper expansion module.
- Buyers deciding which model to choose should keep IEM-3300-4MU on designs that require 2.5G copper and 90-W PoE support, then move to 8P, 16P, or 8T only when the table facts match the required port speed, power class, and port count.
Selection Guide
1. Select it for four multigigabit powered links
Choose IEM-3300-4MU when the bill of materials requires four RJ45 expansion ports that support 1GE/2.5G access and 802.3bt Type 4 PoE on a compatible PoE base system.
2. Move standard PoE density to 8P or 16P
Use IEM-3300-8P or IEM-3300-16P when the deployment needs more powered copper ports but remains on 100/1000Mbps PoE/PoE+ instead of the 4MU module’s 1GE/2.5G 4PPoE profile.
3. Keep data-only copper off this SKU
Select IEM-3300-8T when the expansion requirement is eight 100/1000Mbps RJ45 copper ports without PoE. Substituting it for IEM-3300-4MU removes the 90-W PoE support shown in Cisco’s comparison facts.
4. Verify the host power path
Confirm the base-system family and power design before finalizing the order because Cisco ties IEM-3300-4MU use to PoE base modules and documents the 360W or 480W budget at system level.

Compatible PoE base systems |
Cisco FAQ lists IEM-3300-4MU with IE-3300-8P2S, IE-3300-8U2X, and IE-3400-8P2S families |
Keeps the 4PPoE module out of non-PoE base-switch orders |
|
90-W endpoint support |
Cisco marks IEM-3300-4MU as a 90-W PoE-capable expansion module |
Separates this SKU from IEM-3300-8P and IEM-3300-16P when Type 4 power is required |
|
IE3300 all-Gigabit PoE base |
Cisco documents a 360W total PoE budget with the all-Gigabit base and expansion module |
Prevents endpoint power draw from being calculated as an independent module budget |
|
IE3300 10G and IE3400 PoE base |
Cisco documents up to 480W with IE3300 10G PoE base and IE3400 PoE base contexts |
Forces base-platform confirmation before the 480W budget is assumed |
|
Input voltage planning |
Cisco states 54VDC is required for PoE+ / 4PPoE on IE3300 PoE systems |

Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Exact module PID |
Site SKU IEM-3300-4MU maps to Cisco ordering PID IEM-3300-4MU= |
Prevents the Cisco trailing-equals ordering notation from being treated as a different SKU |
|
Base-system family |
IE-3300-8P2S, IE-3300-8U2X, or IE-3400-8P2S family is the intended host |
Blocks use with non-PoE IE3300 or unrelated industrial-switch platforms |
|
Port and power class |
4 x 1GE/2.5G RJ45 ports with up to 802.3bt Type 4 PoE |
Separates this module from 1G PoE/PoE+ and data-only expansion choices |
|
System PoE budget |
360W all-Gigabit IE3300 PoE context or up to 480W IE3300 10G / IE3400 PoE context |
Keeps endpoint count and power draw inside the documented base-switch budget |
|
PTP requirement |
Cisco notes that IEM-3300-4MU does not support PTP at this time |
Prevents use in designs where PTP support on the expansion ports is mandatory |
|
Expansion count |
One expansion module can be attached to a base system at a time |
Avoids cabinet plans that assume stacked expansion modules |
|
Installation state |
Do not attach the expansion module while the switch is energized |
Aligns the purchase with a planned maintenance window for module installation |
