Description
The VT974 is a 10GbE layer 2 and layer 3 switch with 48 10GbE ports via 48 front panel SFP+. It supports Synchronous Ethernet (SyncE) and IEEE1588.
Cooling and Temperature Sensors
The VT974 has an embedded intelligent Cooling Unit. The cooling airflow is from front to back. Temperature sensors fitted throughout the chassis monitor intake and outtake air temperature and report to the embedded Shelf Manager. The Shelf Manager controls fan speeds for optimized tradeoff between power consumption, noise and cooling. The fans are removable, the power modules are hot-swappable and redundant.
Synchronous Ethernet
The VT974 provides a Synchronous Ethernet (SyncE) on the 10GbE fabric ports. With this feature, ports on the 10G Ethernet switch can be designated as master or slave ports and the Ethernet fabrics within the chassis can be synchronized from end-to-end with external equipment. This feature utilizes advanced telecom-grade network synchronization PLLs to provide exceptional SyncE performance.
