Opengear CM8004-C Console Manager – Compact Smart Out-of-Band Management with 5G Cellular

The Opengear CM8004-C Console Manager is a compact Smart Out-of-Band (Smart OOB™) management appliance with integrated 5G cellular connectivity, designed to keep critical network infrastructure accessible even when the production network or primary WAN connection is unavailable. Featuring four serial console ports, dual Gigabit Ethernet/SFP combo interfaces, dual SIM support, USB connectivity, TPM 2.0 security, and a powerful quad-core ARM platform, the CM8004-C is ideal for branch offices, retail sites, network closets, and remote edge environments where resilient connectivity is essential.

Smart Out-of-Band Management with 5G Cellular Resilience

The Opengear CM8004-C provides an independent management path to critical infrastructure, allowing IT teams to remotely diagnose, configure, and recover equipment when normal network access is unavailable.

Unlike the standard CM8004, the CM8004-C incorporates a global 5G cellular modem, providing an alternative path into the site if primary wired connectivity fails.

Key features include:

• 4 × RJ45 RS-232 serial console ports
• Integrated global 5G cellular modem
• 2 × 4FF nano-SIM slots
• Smart Out-of-Band management
• Dual 1GbE/SFP combo network interfaces
• Secure remote console access
• Automatic network failover
• Network redundancy and aggregation
• Centralised management through Opengear Lighthouse
• Compact design for branch, edge, and remote locations

Global 5G Cellular Connectivity for Network Failover

The major advantage of the CM8004-C over the CM8004 is its integrated 5G cellular capability.

When the primary WAN or management network is unavailable, cellular connectivity can provide an independent route to the console manager, allowing administrators to continue accessing connected infrastructure.

This enables IT teams to remotely troubleshoot devices such as:

• Routers
• Ethernet switches
• Firewalls
• Servers
• UPS systems
• PDUs
• Storage appliances
• Other serial-managed infrastructure

For organisations managing remote or unattended sites, this can turn an otherwise expensive onsite callout into a problem that can be diagnosed and potentially resolved remotely.

The CM8004-C provides two 4FF nano-SIM slots, offering flexibility when deploying cellular services across distributed locations.

Four-Port Serial Console Management

The CM8004-C provides four RJ45 RS-232 serial ports for direct console management of critical infrastructure.

Opengear's current CM8000 documentation specifies Cisco Straight X2 pinout for the CM8004-C serial interfaces, providing straightforward connectivity to compatible network equipment.

The console management platform provides secure, audited access to connected devices and allows administrators to maintain console-level control independently of normal IP management access.

Flexible Gigabit Ethernet and SFP Connectivity

The CM8004-C provides two 1GbE/SFP combo interfaces, allowing organisations to use either copper Gigabit Ethernet or compatible SFP fibre connectivity for each management network connection.

This provides flexibility for:

• Copper or fibre management networks
• Network redundancy
• Automatic failover
• Management network separation
• Branch and edge deployments
• Existing fibre infrastructure

Combined with 5G cellular connectivity, the CM8004-C provides multiple potential paths for maintaining access to critical infrastructure during a network failure.

Remote Power Management and PDU Integration

Console access can resolve many network problems remotely, but sometimes the only solution is to power-cycle an unresponsive device.

The CM8000 Series provides integrated PDU support for remote power control, allowing administrators to manage compatible power infrastructure alongside serial-connected equipment.

This combination of console access and remote power management can help IT teams recover failed routers, switches, firewalls, and other infrastructure without sending someone to the site.

Powerful Automation Platform

The CM8004-C is built on a modern 1.6GHz quad-core ARM platform, with 4GB LPDDR4 memory and 32GB eMMC storage. It supports Docker and automation tools including Python and Ansible, providing considerably more capability than a traditional basic console server.

Automation capabilities include:

• Docker container support
• Python
• Ansible
• Zero Touch Provisioning
• Automated monitoring and remediation
• Remote configuration and management
• API-driven infrastructure workflows

This enables the CM8004-C to act not simply as an emergency console server, but as an intelligent remote management platform at the network edge.

Enterprise Security with TPM 2.0

The Opengear CM8004-C incorporates TPM 2.0 hardware security, providing hardware-backed protection as part of its enterprise security architecture.

Security and access capabilities include:

• TPM 2.0
• Secure SSH and HTTPS administration
• Role-based access controls
• Audited console access
• Enterprise authentication integration
• VPN connectivity
• Secure remote management

This helps organisations provide remote access to critical infrastructure without compromising security simply to gain out-of-band connectivity.

Centralised Management with Opengear Lighthouse

The CM8004-C can be centrally managed using Opengear Lighthouse, allowing IT teams to gain visibility and control across multiple Opengear appliances and geographically distributed locations.

Lighthouse is particularly useful for organisations managing large numbers of branch, retail, edge, or remote locations, providing a central point from which administrators can access their Opengear infrastructure rather than managing each appliance individually.

Compact Design for Branch and Edge Deployments

Opengear designed the CM8000 Series specifically for environments with a small number of serial devices or limited rack space. Typical deployments include branch offices, retail locations, network closets, POPs, and remote edge sites.

The combination of a compact form factor, four serial ports, fibre/copper Ethernet, 5G cellular connectivity, and remote power integration makes the CM8004-C particularly suitable for unattended sites where both space and network resilience are important.

Opengear Support Licence Requirement

Note. All Opengear deployments require a support license, meaning a support option must be included with every new hardware purchase.

Foundation Support delivers day-to-day assurance with regional coverage and advanced hardware replacement.

Premium Support adds 24×7 global coverage, priority escalation, and expert services for complex environments.

Existing Customers: When Foundation or Premium is purchased for any new device, all existing devices under original warranty automatically upgrade at no additional cost for the remainder of the existing term.

Ideal Applications for the Opengear CM8004-C

The CM8004-C is particularly well suited to:

• Branch offices and remote sites
• Retail stores and distributed retail networks
• Network closets
• Telecommunications POPs
• Remote data centre racks
• Managed service provider deployments
• Edge computing environments
• Distributed enterprise networks
• Sites requiring cellular backup management connectivity
• Locations where avoiding onsite support callouts is important

Why Choose the Opengear CM8004-C?

The Opengear CM8004-C takes the compact Smart Out-of-Band capabilities of the CM8004 and adds integrated 5G cellular connectivity, providing another route to critical infrastructure when the primary network fails.

For remote and distributed environments, this is particularly valuable: a WAN outage doesn't necessarily mean losing management access to the site. IT teams can use the independent cellular connection to reach the CM8004-C, access the console of connected equipment, diagnose the failure, make configuration changes, or use integrated PDU support to remotely power-cycle equipment.

With four serial console ports, dual copper/fibre network connectivity, 5G cellular resilience, dual SIM support, TPM 2.0 security, Docker and automation capabilities, and Opengear Lighthouse integration, the CM8004-C provides a powerful compact OOB management solution for branch, edge, and remote infrastructure.
