ADVANCED FEATURES

Secure Out-of-Band Access:

The Dominion SX DSXA-16-DLM is purpose-built for secure out-of-band (OOB) management, ensuring IT administrators can always reach critical infrastructure devices even when the production network is offline or experiencing outages. This capability allows rapid troubleshooting, firmware recovery, and configuration changes without relying on in-band access. In addition, the unit includes a built-in 56K V.90 modem, providing a secondary path via dial-up connectivity for emergency situations where both primary and backup networks may be unavailable. This dual-path approach ensures maximum resilience for enterprise environments.

Scalable Centralised Management:

When integrated with Raritan’s CommandCenter, the DSXA-16-DLM can scale to manage thousands of serially connected devices across data centres and remote branches. Centralised management consolidates authentication, configuration, and monitoring into a unified platform, reducing administrative overhead. It also supports federated policies across multiple sites, ensuring consistent security and compliance enforcement. The platform’s hierarchical organisation capabilities make it easier to group devices by location, department, or function, improving efficiency for distributed IT teams.

Multi-User and Multi-Device Control:

The console server is designed for multi-user environments, supporting up to 320 defined user accounts and enabling up to 10 concurrent sessions per port. This makes it ideal for large teams of administrators, service providers, or managed service operators who need simultaneous access to different devices. Shared access is carefully managed through role-based permissions, ensuring that multiple users can collaborate on troubleshooting without compromising security or device integrity. This flexibility is particularly critical for 24/7 operations and global enterprises with round-the-clock IT support.

Enterprise-Grade Security:

The DSXA-16-DLM incorporates comprehensive enterprise security, with AES 256-bit encryption, SSL/TLS, and SSHv2 protocols ensuring that all communication between administrators and managed devices remains fully protected. Support for RADIUS, LDAP, TACACS+, Kerberos, and Microsoft Active Directory makes it easy to integrate into existing enterprise identity management systems, streamlining user provisioning and access control. Advanced features like account lockout, session timeouts, and two-factor authentication provide further layers of defence against brute-force attacks and unauthorised access attempts, ensuring full alignment with enterprise compliance standards.

Advanced Logging and Auditing:

To meet strict regulatory and operational requirements, the Dominion SX provides comprehensive logging and auditing features. Each user session can be tracked with detailed session logs, which can be exported to external syslog servers for long-term archiving and analysis. Session playback enables administrators to review the exact commands entered during access, helping with both troubleshooting and security investigations. These features not only enhance accountability but also ensure organisations can demonstrate compliance with regulations such as PCI DSS, SOX, and HIPAA.

Redundancy and High Availability:

The device features dual hot-swappable AC power supplies and dual Ethernet ports, ensuring continued access in the event of power or network failures. This high-availability design protects against single points of failure and guarantees always-on management access to critical IT assets. Combined with its 1U rack-mountable design, the DSXA-16-DLM is optimised for high-density deployments in enterprise and service provider data centres. The redundancy architecture also simplifies maintenance, allowing administrators to perform upgrades or replacements without disrupting operations.

Efficient and Sustainable Operation:

Operating at just 8W of power, the Dominion SX is engineered for energy efficiency without sacrificing performance. This low power draw translates to reduced operational costs, particularly in large-scale data centre deployments where power consumption is a critical consideration. The unit supports intelligent power allocation, ensuring that resources are optimally used while minimising energy waste. Its environmentally conscious design also helps enterprises meet sustainability targets and green IT initiatives, contributing to both cost savings and environmental responsibility.

Environmental Resilience and Reliability:

Designed for continuous 24/7 operation, the DSXA-16-DLM is built to handle challenging data centre conditions. It operates reliably in temperatures ranging from 0°C to 40°C and tolerates humidity levels up to 85% non-condensing. The rugged build ensures stability and durability even in high-density rack environments with variable airflow. By combining robust physical resilience with advanced fault tolerance, the device provides long-term reliability, making it an ideal choice for mission-critical enterprise and service provider infrastructures.
