ATEN 16-Port Serial Console Server

Meet the ATEN SN91xxCO series with the SN9116CO 16-port Serial Console Server — a purpose-built solution for centralized, secure, and scalable access to multiple serial devices over IP networks. Designed for data centers, laboratories, industrial environments, and IT operations, this unit consolidates 16 serial connections into a compact 1U chassis, delivering reliable, remote console access with simplified installation. With a single power input and dedicated LAN workflow, the SN9116CO streamlines deployment and reduces complexity while maintaining robust security, granular access control, and comprehensive monitoring. Whether you’re managing network gear, industrial controllers, or legacy equipment, this ATEN console server enables rapid troubleshooting, configuration, and management from anywhere on the network, helping you minimize downtime and optimize operational efficiency.

• Centralized, secure access to every serial device: The SN9116CO provides centralized control over all 16 serial ports, enabling technicians to connect to any device from a single interface. Through its web-based management UI and supported interfaces, administrators can create user accounts with granular permissions, assign port access, and enforce strong authentication. All activity is logged for auditing, and remote sessions are designed to protect sensitive data in transit.
• Scalable 16-port configuration for diverse equipment: The 16-port configuration supports RS-232, RS-422, and RS-485 interfaces, allowing flexible connections to a wide range of devices—from networking gear to industrial controllers. Ports can be configured individually or grouped into profiles, enabling consistent, efficient management across a mixed environment and enabling quick adaptation as your infrastructure evolves.
• Single power and LAN for easy installation: The SN9116CO series emphasizes straightforward setup with a single power input and a dedicated management LAN. Its compact 1U form factor fits neatly into standard 19-inch racks, reducing space requirements and cabling clutter while providing reliable, centralized management for multiple serial devices.
• Out-of-band management with secure remote access: Even when in-band devices are unreachable, administrators can reach serial consoles over the network for troubleshooting, configuration, and control. The console server offers secure authentication, session encryption, and event logging to protect access and provide an auditable trail of activity, helping you maintain uptime and meet security compliance.
• Enterprise-ready features and compatibility: Built to integrate with existing IT ecosystems, the SN9116CO supports standard management workflows and is suitable for data centers, labs, and industrial facilities. It delivers dependable serial console access to legacy and modern equipment alike, with a focus on reliability, ease of use, and scalable performance as your serial device footprint grows.

How to install ATEN 16-Port Serial Console Server

• Unpack the unit and install it in a standard 19" rack using the included mounting ears, or place it on a secure, stable surface if racks are not available.
• Connect up to 16 serial devices to the corresponding ports on the SN9116CO, labeling each port to match the connected equipment for easy identification.
• Connect the Ethernet management port to your network and assign a stable IP address, or configure DHCP if preferred, to enable remote access.
• Connect the power supply to a suitable power source and power on the device. Wait for the management interface to become available.
• Access the web-based management interface from a browser using the assigned IP address. Create an administrator account, configure network and time settings, and apply any required security policies (passwords, MFA if supported).
• Set up port profiles and user roles to control who can access each serial port, and define logging and alert preferences to monitor activity and device health.
• Test a remote serial session by selecting a connected port, initiating a session, and verifying command execution, response times, and reliable data transmission.
