About the Cisco ISR 2900 CISCO2911/K9 Cisco Integrated Services Router (ISR)
The Cisco ISR 2900 (part number CISCO2911/K9) is a 1U rack-mountable integrated services router built for enterprise branch offices and distributed sites requiring converged routing, security, and voice capabilities. This Cisco platform consolidates WAN connectivity, LAN switching, security services, and unified communications into a single appliance, reducing hardware footprint and operational complexity for network engineers and IT procurement teams tasked with managing multi-site deployments.
Equipped with integrated IPsec VPN, Zone-Based Firewall, and IPS functionality (license-dependent), the ISR 2900 delivers essential security without dedicated appliances. Voice support is available through Cisco Unified CME and Cisco Unity Express modules, enabling organizations to unify data and telephony over IP networks. The router supports Cisco IOS with migration to IOS-XE, ensuring long-term software compatibility and feature evolution. With 4 EHWIC slots, 2 Service Module slots, and 1 Internal Services Module slot, the platform offers extensive modularity for scaling services as business needs grow. A single 200W internal AC power supply keeps infrastructure costs minimal, with optional PoE availability through compatible modules.
