NIM-ES2-4 Description
The NIM-ES2-4 is a Cisco 4-port Layer 2 Gigabit Ethernet LAN Switch Network Interface Module for branch routers that terminate local wired devices on the router itself. The module has four 10/100/1000BASE-TX switched ports with line-rate Layer 2 forwarding and four QoS queues per port, and it reaches other LAN switch NIMs in the router over the multigigabit fabric. The module has no PoE, and it runs on IP Base and later images without a feature license.

None; PoE and PoE+ at up to 30W per port is provided by the 8-port PoE version |
|
Software requirement |
IP Base and later images, with no Cisco IOS technology or feature licenses required |
Application Scenarios
In a small branch, the module gives a Cisco 4000 Series ISR four Gigabit Ethernet ports for desktops and printers, so those devices connect to the router without a separate access switch.
Where a branch router terminates local devices, the four QoS queues per port and Shaped Deficit Weighted Round Robin scheduling keep latency-sensitive traffic ahead of bulk transfers.

Port Count Against The Eight-Port Module
NIM-ES2-4 provides four switched Gigabit Ethernet ports while NIM-ES2-8 provides eight on the same Layer 2 architecture and without PoE; a site that will terminate more than four local devices consumes the same NIM slot either way, so the port count is the whole difference between those two order lines.
Inline Power Sits Only On The PoE Module
Neither NIM-ES2-4 nor NIM-ES2-8 delivers inline power. NIM-ES2-8-P is the module capable of powering all eight of its ports at up to 30W of PoE or PoE+ per port with per-port monitoring and policing, so a design with powered endpoints has one option among the three.
Software Entitlement Is Not A Separate Line
The Gigabit Ethernet LAN Switch NIMs are supported in IP Base and later images and Cisco states no technology or feature licenses are required, so the module does not add a license line item to the order the way a routing feature set would.
Selection Guide
NIM-ES2-4 suits Cisco 4000 Series ISRs with a free NIM slot that need up to four non-PoE Gigabit Ethernet drops on the router itself. Sites with more than four wired devices move to NIM-ES2-8, and branches that must power phones, access points or cameras from the module need NIM-ES2-8-P, which supplies up to 30W of PoE/PoE+ per port. Cisco lists the switch NIMs for IP Base and later images, with no feature license.
Ordering Checklist
- Cisco 4000 Series hosts: Order NIM-ES2-4= for a Cisco 4000 Series ISR with a free NIM slot. The module fits only a NIM slot on the router.
