622 MB/s peak per link in each direction
5.0 GB/s peak to the backplane
48.0 VDC ±5%, main power
05.0 VDC ±5%, management power
Input voltages measured at the backplane pins inclusive of all ripple.
Mercury strongly recommends that system-level power designs use a ±2% margin to avoid any potential issues with respect to the system-level operating characteristics and operating environment.

*As altitude increases, air density decreases and, therefore, the cooling effect of a particular number of CFM decreases. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Contact Mercury for more information.
