Cisco 2821 Integrated Services Router NME-WAE-502-K9 WAAS Module and WIC-1DSU-T1-V2

Modular Cisco 2821 Base Router for Flexible Branch Network Expansion

The Cisco 2821 Integrated Services Router provides a modular platform designed for evolving branch connectivity, equipped with dual Gigabit Ethernet interfaces and multiple expansion bays to support diverse WAN, LAN, and service integrations. This unit offers the standard 2821 hardware architecture without optional network, voice, or WAN interface modules installed, delivering a clean foundation ready for custom deployment needs. :contentReference[oaicite:0]{index=0}

Core Hardware Architecture with Open Expansion Capacity

• Two onboard Gigabit Ethernet interfaces for LAN/WAN routing
• Four empty HWIC slots for WAN, voice, or switching expansion
• Unpopulated network module slot for NME or NME-X modules
• Open PVDM banks supporting up to three DSP modules
• Integrated CompactFlash storage installed for IOS and configuration files

Performance Foundation for Multi-Service Branch Routing

With its modular design and dual Gigabit Ethernet ports, the Cisco 2821 supports a wide range of service integrations when equipped with appropriate modules. The chassis architecture enables WAN connectivity, security services, voice processing, or switching functions through compatible HWIC, NME, AIM, or PVDM components. Its empty slots provide full flexibility for tailored deployments where hardware must match specific carrier or service requirements. :contentReference[oaicite:1]{index=1}

Deployment Scenarios for Base Chassis Configurations

• General-purpose branch routing with customizable module installation
• Staging environments requiring a clean, unconfigured hardware platform
• Integration into modular networks where add-on cards will be installed on demand
