Cisco C819-4P-K9 Full Product Description

1. Short Overview

Suffix Breakdown

• C819: Ruggedized industrial M2M router platform of Cisco 800 Series
• 4P: Integrated 4-port Fast Ethernet managed LAN switch
• -K9: Permanent Cisco cryptographic license bundle enabling AES-256, IPsec, IKEv1/IKEv2 full encryption suite

Core Differentiators

1. vs cellular C819G-4P-K9: C819-4P-K9 has no onboard 3G/4G LTE WWAN modem; G variants add cellular dual-SIM wireless WAN failover.
2. vs Wi-Fi-equipped C819-4P-CIFI-K9: No integrated dual-band 802.11n wireless access point radio, purely wired edge gateway design.
3. vs desktop C812-K9: C812 is indoor commercial desktop with only 2 GE ports; C819 features rugged fanless chassis, wide industrial temperature range, 4-port managed FE switch and serial WAN interface for industrial field sites.
4. vs higher-end C829 rugged routers: C819 offers cost-optimized entry-level industrial wired routing with smaller footprint and lower power draw for light M2M workloads.
