Cisco ISR4431/K9 Integrated Services Router w/ NIM-2GE-CU-SFP, Dual 400W PSU, HSEC, APPX & SecurityK9
The Cisco ISR4431/K9 is a 1U modular enterprise Integrated Services
Router designed for WAN connectivity, branch networking, VPN,
security, application services, and advanced routing deployments.
This configuration includes one Cisco NIM-2GE-CU-SFP Network Interface
Module, two 400W AC power supplies for redundant power, and HSEC-K9,
APPXK9, and SecurityK9 license functionality as specified for this unit.
The ISR4431 provides four onboard logical Gigabit Ethernet interfaces.
The installed NIM-2GE-CU-SFP adds two additional dual-mode Gigabit
Ethernet interfaces capable of using copper RJ45 or compatible SFP
media, providing six logical routed Gigabit Ethernet interfaces in
this configuration.

- Layer 2 VPN features
- Layer 3 VPN features
- Broadband features
- Application Visibility and Control functionality
- Exact feature availability depends on IOS XE release
Performance
- Base aggregate throughput: 500Mbps
- Upgradeable to 1Gbps aggregate throughput with the appropriate Cisco Performance license
- The FL-44-PERF-K9 Performance license is separate from HSEC-K9
- Do not assume 1Gbps Performance licensing solely because HSEC is installed

Important Notes
- Photos are for reference only.
- Only listed items are included.
- The NIM-2GE-CU-SFP provides two logical Ethernet interfaces, not four simultaneous RJ45/SFP interfaces.
- SecurityK9 is the correct Cisco license name; it may appear in IOS XE as securityk9.
- HSEC-K9 and the router Performance license are separate licenses.
- HSEC-K9 does not by itself upgrade ISR4431 system throughput from 500Mbps to 1Gbps.
- License state and entitlement behavior vary depending on IOS XE release and Cisco licensing model.
- Verify compatibility before purchase.
