Opengear CM8004 Console Manager – Compact Smart Out-of-Band Management for Remote and Edge Sites

The Opengear CM8004 Console Manager is a compact, next-generation Smart Out-of-Band (Smart OOB™) management appliance designed to keep critical network infrastructure accessible when the production network is unavailable. Featuring four serial console ports, dual Gigabit Ethernet/SFP combo interfaces, USB console management, remote power integration, modern automation support, and TPM 2.0 security, the CM8004 is ideal for branch offices, retail sites, network closets, and remote edge environments where rack space is limited.

Compact Smart Out-of-Band Management

The Opengear CM8004 provides secure, independent access to network infrastructure so IT teams can remotely diagnose, configure, and recover equipment during outages without relying on the production network.

Key features include:

• 4 × RJ45 RS-232 serial console ports
• Opengear Smart Out-of-Band management
• Secure remote console access
• Dual Ethernet connectivity with redundancy and aggregation support
• Automatic network failover
• Browser-based management interface
• IPv6 support
• Multiple concurrent console sessions
• Console event and keystroke logging
• Text pattern matching and alerting
• Centralised management through Opengear Lighthouse

Opengear positions the CM8000 Series specifically for environments with a small number of serial devices or limited rack space, including branch offices, retail locations, network closets, POPs, and remote edge sites. (OpenGear Resources)

Four-Port Serial Console Access

The CM8004 provides four RJ45 RS-232 serial ports for direct management of infrastructure such as:

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

The serial ports support Cisco-compatible X2 pinout connectivity and serial speeds from 50 to 115,200bps. Opengear also provides built-in browser terminal access and IP aliases for direct connections to individual serial consoles. (OpenGear Resources)

Flexible Gigabit Ethernet and SFP Connectivity

The CM8004 includes two combination network interfaces, allowing each connection to use either copper Gigabit Ethernet or SFP fibre connectivity.

This provides deployment flexibility for enterprise, branch, and remote infrastructure environments, with support for:

• 100BASE-TX / 1000BASE-T Ethernet
• Gigabit SFP connectivity
• Ethernet aggregation
• Network redundancy
• Automatic network failover
• Dedicated management network architectures

This combination of copper and fibre connectivity makes the CM8004 particularly useful where management networks need to integrate with existing fibre infrastructure. (OpenGear Resources)

Remote Power Control and PDU Integration

The CM8000 Series adds integrated support for remote power management, enabling administrators to manage compatible PDUs alongside serial-connected infrastructure.

This allows IT teams to combine console access with remote power control, helping recover equipment that cannot be restored through configuration changes alone. A frozen router, firewall, switch, or other device can potentially be remotely power-cycled rather than requiring an engineer to travel to the site.

Modern Automation with Docker, Python and Ansible

Unlike traditional basic console servers, the CM8004 is built on a modern 1.6GHz quad-core ARM Cortex-A53 platform with 4GB LPDDR4 memory and 32GB eMMC storage.

Its automation capabilities include:

• Docker container support
• Python
• Ruby
• Ansible
• Zero Touch Provisioning (ZTP)
• API-based management
• SNMP standard MIB support

These capabilities allow organisations to automate deployment, monitoring, remediation, and infrastructure management tasks directly at remote sites. (OpenGear Resources)

Enterprise Security with TPM 2.0

The Opengear CM8004 incorporates hardware and software security features designed to protect access to critical infrastructure.

Security capabilities include:

• Trusted Platform Module (TPM) 2.0
• TACACS+
• RADIUS
• Active Directory and OpenLDAP integration
• Local authentication fallback
• IPSec
• OpenVPN
• Secure HTTPS and SSH administration
• Role-based access controls
• Audited console access

The embedded TPM provides hardware-backed security for cryptographic operations and device identity. (OpenGear Resources)

Centralised Management with Opengear Lighthouse

The CM8004 integrates with Opengear Lighthouse, allowing multiple Opengear appliances and their connected infrastructure to be centrally monitored and managed.

Lighthouse provides administrators with centralised visibility and access across geographically distributed sites, helping organisations scale out-of-band management without individually administering each console manager. (Opengear - Network Resilience Platform)

Compact Half-Rack Design

The CM8004 is designed specifically for environments where space is at a premium.

Its compact 1RU half-rack-width form factor measures approximately 220 × 177 × 44mm and uses passive cooling, allowing it to be forward or reverse mounted. An optional rack tray can convert the appliance for standard full-width 1RU rack installation. (OpenGear Resources)

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

The CM8004 is particularly well suited to:

• Branch offices
• Retail locations
• Network closets
• Remote edge sites
• Small data centre racks
• Telecommunications POPs
• Managed service provider deployments
• Distributed enterprise networks
• Industrial and utility infrastructure

Why Choose the Opengear CM8004?

The Opengear CM8004 brings modern Smart Out-of-Band management to smaller and space-constrained locations without sacrificing enterprise capabilities. Its four serial console ports, flexible copper/fibre management interfaces, PDU integration, powerful automation platform, TPM 2.0 security, and Lighthouse integration provide IT teams with a reliable way to access and recover critical infrastructure when the production network is down.

Compared with older basic console managers, the CM8004 is designed as a modern recovery platform: compact enough for branch and edge deployments, but powerful enough to support automation, remote power management, secure centralised access, and scalable enterprise operations.
