Cisco 892FSP 1 GE and 1GE/SFP High Perf Security Router

Cisco C892-K9 V02 – High-Performance Integrated Services Router with 1 GE + 1 GE/SFP WAN, Built-in Firewall & Security for Small Enterprise & Branch Offices

The Cisco C892-K9 V02 (also known as the Cisco 892FSP) is a compact, high-performance Integrated Services Router (ISR) from Cisco’s 890 Series, purpose-built for small enterprises, branch offices, and secure remote connectivity. Combining integrated Gigabit Ethernet and fiber-ready SFP uplinks, hardware-accelerated security, and advanced threat defense, the C892-K9 delivers enterprise-grade routing, firewall, and VPN capabilities in a single, fanless desktop appliance.

Pre-loaded with the Cisco IOS K9 security image, this router enables encrypted communications, stateful firewalling, intrusion prevention, and secure remote access—making it ideal for organizations requiring compliance-ready, resilient, and manageable WAN edge protection without the complexity of multi-device deployments.

Key Features & Specifications

  • 1 x Gigabit Ethernet (RJ45) WAN port
  • 1 x Gigabit Ethernet/SFP combo WAN port (supports copper or fiber via SFP module)
• LAN Switching:
  • 8 x 10/100/1000BASE-T managed switch ports (Layer 2 with VLAN, QoS, and security)
• Security & Performance:
  • Cisco IOS Firewall with Zone-Based Policy Firewall (ZBFW)
  • IPSec VPN (site-to-site and remote access)
  • Intrusion Prevention System (IPS)
  • Content Filtering & URL Blocking
  • Hardware-accelerated encryption (AES, 3DES) via K9 crypto image
  • WAN Throughput: Up to 150 Mbps with security services enabled
  • VPN Throughput: Up to 75 Mbps
• Voice Support: Optional Cisco Unified Communications Manager Express (CME) for IP telephony (licenses and DSPs required)
• Management:
  • Cisco IOS CLI
  • Cisco Configuration Professional (CCP)
  • SNMP, NetFlow Lite
  • Limited support for Cisco DNA Center
• Form Factor: Compact, fanless desktop design (ideal for quiet office environments)
• Power: Internal AC power supply (100–240V)

Note: The “K9” indicates the router includes the strong cryptographic (security) IOS image, enabling full VPN and encrypted management. The “V02” denotes a specific hardware revision, often with updated components or regional compliance.

Dual WAN Flexibility: Copper + Fiber in One Device

A standout feature of the C892FSP is its dual WAN capability:

• Primary WAN: Gigabit Ethernet (RJ45) for cable, DSL, or fiber ONT
• Secondary/Failover WAN: GE/SFP combo port—use copper for cost efficiency or insert an SFP module (e.g., 1G LX/SX) for fiber uplinks to service provider networks

This enables: ✅ Hybrid WAN deployments (e.g., broadband + fiber)
✅ Automatic failover for business continuity
✅ Future-proofing—upgrade to fiber without replacing the router

SFP modules sold separately (e.g., GLC-LH-SMD, GLC-SX-MMD).

Enterprise Security in a Small Footprint

The C892-K9 V02 delivers comprehensive threat protection:

• Stateful Inspection Firewall: Control traffic between zones (e.g., LAN, WAN, DMZ)
• IPSec VPN: Securely connect branches to HQ or cloud (AWS, Azure)
• Intrusion Prevention (IPS): Block exploits, worms, and known attack patterns
• Secure Remote Management: SSH, HTTPS, ACLs
• Compliance Support: Meets baseline requirements for PCI DSS, HIPAA, and GDPR when properly configured

All security functions are hardware-accelerated, minimizing performance impact during encrypted traffic inspection.

Integrated Switching for Simplified Networking

The built-in 8-port Gigabit switch eliminates the need for a separate access switch:

• VLAN segmentation (e.g., guest, corporate, IoT networks)
• Port security and 802.1X authentication
• QoS for prioritizing voice/video traffic
• PoE pass-through support on select ports* (verify exact model configuration)

*Note: The base C892-K9 does not include PoE; PoE models are designated separately (e.g., C892FSP-K9).

Ideal Use Cases

• Small business headquarters needing secure internet, switching, and fiber readiness
• Branch offices requiring encrypted site-to-site connectivity
• Retail stores with PCI-compliant payment systems
• Professional offices (legal, medical) handling sensitive data
• Remote sites using fiber for low-latency cloud access
