System Overview
MC1600 Extreme Edge Server Installation and Use (6806870A02A) 37
1.3 Cooling
The Extreme Edge Server has seven identical fans on the inlet (right) side of the system. The
BMC monitors all fan tachometer readings, when fans are powered on, and at what speed the
fans run.
The BMC sets the fan speed based on sensor data within the system. For more information see
Aggregated Temperature Sensors on page 104 .
1.4 Grounding
The Extreme Edge Server has a common logic ground as signal reference for the base board,
DIMMs, M.2 modules, heater control circuits, and PCIe card. Chassis ground uses the chassis
metal and front panel connector shields.
Within the system, logic ground and chassis ground
are connected at a single point to ensure a common potential while avoiding the possibility of
ground loops. The -48V RTN is isolated from logic ground and chassis ground in the system.
