Cisco Integrated Services Router 4321 - Unified Communications Bundle - Router - GigE - WAN Ports: 2 - Rack-mountable - Refurbished - ISR4321-V/K9-RF

• High performance
  Cisco ISR 4321 features a distributed multicore architecture with internal services plane.
• Lower WAN expenditures
  Embedded IWAN solution is designed for creating lower-cost, business-class Internet connections.
• Superior and secure user application experiences
  Secure boot feature performs hardware-based authentication of the boot loader software to prevent malicious or unintended software from booting on the system. Code signing verifies digital signatures of executables prior to loading to prevent execution of altered or corrupted code. Hardware authentication protects against hardware counterfeiting by using an on-board tamper-proof silicon, including field replaceable modules. If authentication fails, the module is not allowed to boot.
• IT consolidation, space savings, and improved total cost of ownership (TCO)
  Single converged branch platform integrates routing, switching, virtual server, storage, security, unified communications, WAN optimization, and performance management tools.
• Business continuity and increased resiliency
  Cisco ISR 4321 features modular network interfaces with diverse connection options for load-balancing and network resiliency and modular interfaces with online removal and insertion (OIR) for module upgrades without network disruption.

The Cisco 4000 family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. With amazing levels of built-in intelligent network capabilities and convergence, it specifically addresses the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources. But they often also have a growing need for direct communication with both private data centers and public clouds across diverse links, including Multiprotocol Label Switching (MPLS) VPNs and the Internet. The Cisco 4000 series ISRs consolidate many must-have IT functions, including network, compute, and storage resources. The high-performance, integrated routers run multiple concurrent IWAN services without slowing your data throughput.
