Opengear CM8004-C 4-portový RS232 sériový konzolový server s duálnym Gigabit Ethernet/SFP Combo a duálnym USB 3.0, ARM procesor

Network administrators managing distributed IT infrastructure—from branch offices to industrial sites—rely on the Opengear CM8004-C for secure, out-of-band access to critical serial devices. This console server consolidates four RS232 ports alongside dual Gigabit Ethernet/SFP combo uplinks and dual USB 3.0 ports, enabling centralized management of routers, switches, firewalls, and legacy equipment even when the primary network is down.

Key specifications

• 4 x RS232 serial ports (RJ45) with software-selectable pinouts for direct console connections
• 2 x Gigabit Ethernet ports with SFP combo slots for fiber or copper uplink flexibility
• 2 x USB 3.0 ports for storage, cellular modem failover, or peripheral expansion
• ARM-based processor for reliable, low-power operation
• Rack-mountable 1U form factor with included mounting brackets
• Advanced security: SSH, HTTPS, IPsec VPN, and RADIUS/TACACS+ authentication
• Zero-touch provisioning and automated configuration via Opengear Lighthouse or REST API

Why choose it

The CM8004-C stands out with its dual Gigabit/SFP combo ports, offering redundant uplink options that many entry-level console servers lack. Its ARM architecture ensures efficient performance without excessive heat or power draw, making it suitable for always-on deployments. With four RS232 ports, it scales to manage multiple devices from a single access point, reducing the need for multiple console servers in small to medium-sized cabinets.

Ideal use cases

• Out-of-band management for branch office routers, switches, and firewalls
• Remote access to industrial control systems, POS terminals, and lab equipment
• Failover connectivity via USB cellular modem when primary WAN fails
• Centralized console access for colocation or managed service provider environments

Good to know

The CM8004-C supports Opengear's Smart OOB™ features, including automatic health checks and failover to secondary interfaces. It integrates seamlessly with Lighthouse Centralized Management for fleet-wide updates and monitoring. The device includes a 12V DC power supply and can be powered via PoE (Power over Ethernet) on the primary Gigabit port, simplifying installation in remote locations.
