ATEN 48-Port Serial Console Server with Dual Power/LAN

Introducing the ATEN SN01xxCO series, the next generation of Serial Console Servers designed to simplify, secure, and scale remote access to large fleets of serial devices. Available in SN0108CO, SN0116CO, SN0132CO, and SN0148CO configurations, these units combine rugged reliability with enterprise-grade management capabilities. Dual power and dual LAN architecture deliver unmatched uptime, while flexible port configurations and advanced security features make them ideal for data centers, network operations centers, industrial facilities, and distributed IT environments. Whether you’re consolidating legacy RS-232/RS-422/RS-485 devices or enabling remote console access for dozens of servers, ATEN’s SN01xxCO series provides a compact, rack-mountable solution that reduces on-site visits and accelerates maintenance across critical infrastructure.

• Scalable port options: Choose 8, 16, 32, or 48 serial ports across the SN0108CO, SN0116CO, SN0132CO, and SN0148CO models. Each port supports reliable serial console access, terminal emulation, remote power cycling, and centralized control for a broad range of servers, network devices, and industrial equipment.
• Dual power and dual LAN redundancy: Two independent power supplies provide hot-swappable, fail-safe operation, ensuring continuous service during maintenance or power events. Dual LAN ports enable network path redundancy, isolating management traffic and boosting resilience in busy data centers.
• Secure, authenticated remote access: Delivering robust security with SSH, SSL/TLS, and a web-based GUI, the SN01xxCO series supports role-based access control and integration with centralized authentication systems such as RADIUS and TACACS+. Your serial sessions remain encrypted, auditable, and protected against unauthorized access.
• Advanced management and visibility: Real-time port status, comprehensive event logging, SNMP support, and a centralized management console enable proactive monitoring, rapid troubleshooting, and streamlined compliance. Features like port redirection, session history, and alerting help operators maintain tight control over critical devices.
• Easy deployment in rugged environments: The compact, 1U rack-mountable chassis is designed for dense data centers and remote installations. Front-panel indicators, modular components, and straightforward cabling simplify installation, service, and maintenance while keeping noise and footprint to a minimum.

How to Install ATEN 48-Port Serial Console Server with Dual Power/LAN

To deploy the SN01xxCO series effectively, prepare a suitable rack space and the required cabling. Begin by powering down equipment in the target rack and ensuring you have a clean, ventilated environment for stable operation. Install the chassis in a 19-inch rack using the included rails or brackets, and secure the unit firmly to prevent movement.

Next, connect your serial devices to the appropriate RJ-45 console ports. Take a careful inventory of each device’s serial settings (baud rate, data bits, parity, stop bits) so you can mirror these configurations in the console server for accurate terminal access and logging. Route the serial device cables neatly to the corresponding ports on the SN01xxCO unit to avoid cross-wiring or accidental disconnections.

Attach the dual redundant power supplies to certified power sources or an uninterruptible power supply (UPS). Ensure both supplies are receiving power and that power indicators reflect healthy operation. For environments requiring network resilience, connect both LAN ports to your core network or to separate switches, enabling management traffic to remain available even if one path experiences congestion or failure.

Power on the unit and begin the initial setup. Use a connected computer to access the device’s web-based management interface via the default IP address or via a DHCP-assigned address. Create an administrative account with strong credentials and enable basic security features such as SSH or TLS encryption. Configure user roles and access controls to align with your organization’s security policy. As you configure the SN01xxCO, map each serial port to the device or group of devices it will control, and set up port forwarding rules or terminal defaults to streamline daily operations.

Implement redundancy and monitoring settings. Enable SNMP traps and alerting so your network operations team receives timely notifications of port status changes, power events, or connectivity issues. Review the system logs regularly to identify patterns or recurring problems, and adjust firewall rules, access controls, or port configurations as needed. Finally, document the configuration for future audits and share the operational procedures with the IT staff responsible for serial device management.

For ongoing maintenance, schedule firmware updates as offered by ATEN and verify that dual power and dual LAN paths remain active after any routine changes. Maintain a clean cabling layout to minimize interference and ensure serviceability, and test remote access from multiple locations to confirm that administrators can reliably reach the serial devices even during network outages.

In summary, the SN01xxCO is designed to simplify deployment, tighten security, and maximize availability. By following these installation steps and adopting best-practice management habits, you’ll achieve a scalable, secure, and centralized console environment that reduces on-site visits and enhances control over critical serial infrastructure.
