Cisco C819HG-4P-K9 Full Product Description

1. Short Overview

Suffix Breakdown

• C819: Industrial M2M fanless ISR platform of Cisco 800 Series
• HG: Hardened Grade industrial ruggedized chassis, wide temperature, shock & vibration certified
• 4P: Built-in 4-port 10/100BASE-T managed Fast Ethernet LAN switch
• -K9: Permanent Cisco crypto license bundle enabling AES-256, IPsec, IKEv1/IKEv2 full encryption suite

Core Differentiators

1. vs non-hardened C819-4P-K9: C819-4P-K9 is standard commercial indoor model with limited temperature range; C819HG-4P-K9 is fully hardened for vehicle, outdoor cabinet and extreme industrial environments, compliant with MIL-STD-810G, SAE J1455 and NEBS Level 3 shock/vibration standardsCisco.
2. vs cellular C819HG-4G-4P-K9: No embedded 3G/4G LTE dual-SIM cellular modem; cellular HG variants provide primary/backup wireless WAN failover.
3. vs Wi-Fi C819HGW-4P-K9: Lacks integrated dual-band 802.11n wireless AP radio, purely wired hardened gateway design.
4. vs C819HG-8P-K9: Only 4 FE LAN ports versus 8-port high-density switch for lighter M2M device aggregation deployments.
5. vs desktop C812-K9: C812 is plastic indoor desktop with only two GE ports; C819HG-4P-K9 uses heavy-duty metal fanless DIN-rail hardened chassis, wide -40°C ~ +60°C operating range, serial WAN and managed FE switch for field harsh conditions.
