NIM-ES2-8-P Description
NIM-ES2-8-P is a Cisco 8-port PoE/PoE+ Gigabit Ethernet LAN Switch Network Interface Module for Cisco 4000 Series ISR deployments that need local switched Ethernet expansion inside the router. It provides eight 10/100/1000BASE-TX RJ-45 switched ports, IEEE 802.3af PoE and IEEE 802.3at PoE+ support with up to 30W per port, Layer 2 switching across the onboard Gigabit Ethernet ports, single-wide NIM form factor, and platform support for Cisco 4321, 4331, 4351, 4431, and 4451 routers. The module adds integrated PoE access ports to a branch ISR without requiring a separate access switch.

Application Scenarios
Use NIM-ES2-8-P when a Cisco 4000 Series ISR must provide local Gigabit Ethernet access ports for branch endpoints without adding a separate standalone access switch.
Select this module for IP phones, wireless access points, or video endpoints that require PoE or PoE+ from the router-based switch module, with the final port count governed by the ISR PoE power supply plan.
Deploy NIM-ES2-8-P where the design benefits from onboard Layer 2 switching, VLAN trunking, voice VLAN support, and internal MGF communication between supported LAN switch NIMs.

- In a NIM-ES2-8-P vs NIM-ES2-8 comparison, the key difference is PoE/PoE+ support: NIM-ES2-8-P supports IEEE 802.3af and IEEE 802.3at powered endpoints, while NIM-ES2-8 is the eight-port non-PoE model.
- The NIM-ES2-8-P vs NIM-ES2-4 difference combines power and density: NIM-ES2-8-P has eight Gigabit Ethernet ports with PoE/PoE+, while NIM-ES2-4 has four non-PoE ports in the same LAN switch NIM family.
- For buyers deciding which model to choose, the NIM-ES2-8-P comparison should start with endpoint power needs, Cisco 4000 Series router support, and whether Cisco 4221 support is required.
Selection Guide
1. Choose it when eight powered access ports belong in the ISR
Select NIM-ES2-8-P when the branch router BOM requires eight onboard Gigabit Ethernet switch ports and PoE or PoE+ for connected endpoints.
2. Move to NIM-ES2-8 when power is not required
Use NIM-ES2-8 instead when the design needs the same eight switched Gigabit Ethernet ports but the endpoint power source is separate from the router.
3. Downshift to NIM-ES2-4 for a smaller non-PoE port count
Choose NIM-ES2-4 only when four non-PoE Gigabit Ethernet ports are enough and the narrower 4-port NIM form factor matches the site requirement.
4. Verify router and PoE supply before approval
Confirm the target Cisco 4000 Series ISR, PoE system power supply, and software baseline because available powered ports depend on the platform and power mode.
PoE Power Planning
|
Review Area |
Cisco-Confirmed Boundary |
Buyer Impact |
|---|---|---|
|
Per-port power class |
NIM-ES2-8-P supports PoE and PoE+ with up to 30W per port |
Endpoint classes must be matched before assuming all eight ports can run at the same draw |
|
Router power mode |
Cisco documents normal mode with one PoE power supply and boost mode for dual PoE supplies on Cisco 4431 and 4451 |
The same module can have different usable PoE totals by ISR model and power-supply design |
|
Platform output |
Cisco lists normal-mode PoE output of 110W on 4321, 250W on 4331 and 4431, and 500W on 4351 and 4451 |
Phone, AP, and camera counts should be calculated from the router power table, not from the module port count alone |
|
30W powered ports |
Cisco lists normal-mode 30W port counts of 3 on 4321, 8 on 4331, 16 on 4351, 8 on 4431, and 16 on 4451 |
A full eight-port PoE+ plan may fit some platforms but not every supported ISR power profile |
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Router platform |
Cisco 4321, 4331, 4351, 4431, or 4451 support context from Cisco’s data sheet table |
Keeps the 8-port PoE module out of a Cisco 4221 order where the platform table lists NA |
|
PoE power supply |
PoE system power supply and, where applicable, redundant or boost power mode |
Controls how many endpoints can draw power from the module |
|
Endpoint power demand |
IEEE 802.3af or IEEE 802.3at class for each phone, AP, or camera |
Avoids treating eight physical ports as eight guaranteed 30W loads |
|
Software support |
IP Base and later image support with the documented Cisco IOS XE baseline |
Aligns hardware ordering with Cisco’s software support table |
|
Module count |
Maximum number of supported LAN switch NIMs for the selected ISR model |
Prevents overfilling the router expansion plan |
|
Cabling |
RJ-45 cabling for 10BASE-T, 100BASE-TX, or 1000BASE-TX endpoint links |
Keeps the access-port plan matched to copper Ethernet media |
