Orolia’s NetClock Model 9489 delivers worldwide, split-second timing for an NTP network with the highest security, reliability, and ease of management. It is designed for applications requiring an affordable but state-of-the-art GPS NTP server.
For today’s network and computer systems that require time-sensitive data for such tasks as logging events, records management, network optimization and troubleshooting, and synchronizing operations, we offer our high performance NTP server technology in this specific NetClock model, and as a direct replacement for previous generation models: 8189, 9189, 9289, and 9389.
- Secure network management: enable or disable protocols
- IPv4/IPv6 dual stack
- Alert notifications via SNMP Traps and e-mail alerts
- CLI/SSH access for automation and scripting
- Best-in-class 5-year warranty
The model 9489 can track up to twelve GPS satellites simultaneously, providing highly accurate timing by synchronizing to the satellites’ atomic clocks. A variety of time codes on dual ports are included to meet the requirements of numerous systems. A 1PPS signal is also available for device synchronization and advanced testing.
Enhanced security features ensure operational integrity and can be enabled or disabled based on your needs. These features include remote login and file transfer capabilities, providing the utmost security using industry standard interfaces.

The simplicity of installation, ease of management, and reliable operation of the 9489 reduces the cost of network administration. It includes full SNMP capability, support for enterprise directory servers to authenticate users, internal and external logging and monitoring of error messages through Syslog, SNMP Traps and e-mail alert notifications, DHCP for installation convenience, and IPv4/IPv6 dual stack for future network modernization. A new browser-based user interface allows for easy monitoring and configuration changes.
