About the Cisco ISR 3900 CISCO3925-CHASSIS Cisco Integrated Services Router (ISR)
The Cisco ISR 3900 series (part number CISCO3925-CHASSIS) delivers dense WAN and LAN connectivity through three onboard 10/100/1000BASE-T Gigabit Ethernet ports, complemented by four Enhanced High-Speed WAN Interface Card (EHWIC) slots and three Service Module (SM) slots for granular network expansion. This 2U rack-mount platform supports four PVDM slots and integrated hardware encryption acceleration for IPsec VPN, enabling secure high-performance branch and edge deployments without sacrificing modularity or throughput.
Built on the Cisco ISR G2 3900 Series architecture, the ISR 3925 runs Cisco IOS and IOS XE operating systems, supporting IP Base, Security, Unified Communications, Data, and AppX feature sets. The platform integrates an AC power supply (350W) with optional redundant power supply support, two USB 2.0 ports, a CompactFlash slot, and dedicated RJ-45 console and auxiliary ports for out-of-band management. Network engineers and IT procurement teams seeking flexible, secure routing solutions for branch consolidation and WAN edge operations will find the CISCO3925-CHASSIS a capable foundation. Dimensions of 3.47 in × 17.3 in × 18.0 in fit standard rack environments, and the unit operates reliably across 0°C to 40°C ambient conditions.
Enterprise Deployment Scenarios
- Branch office WAN aggregation with IPsec VPN encryption and multiple carrier circuit support via EHWIC expansion
- Unified Communications edge deployment combining routing, voice, and security services on a single platform
- Multi-service edge consolidation reducing datacenter footprint and operational complexity
- Secure remote site connectivity with integrated encryption acceleration and failover power redundancy
- Application-aware networking and traffic shaping for distributed enterprise environments
