3.4 Onboard Jumpers

NOTE:

A jumper is a metal bridge that is used to

close an electrical circuit. It consists of

two metal pins and a small metal clip

(often protected by a plastic cover) that

slides over the pins to connect them. To

CLOSE/SHORT a jumper means

connecting the pins of the jumper with

the plastic clip and to OPEN a jumper

means removing the plastic clip from a

jumper.

The ROCKY-4786EVG CPU Board has two onboard jumpers. See Table 3-3.

 Thermal Management [Thermal Monitor 1]

1-93

The Thermal Management configuration option allows you to select the thermal monitor

the CPU will use to monitor its own operating temperature. Once the thermal monitor

detects that the CPU is reaching its maximum operating temperature, the thermal monitor

will automatically throttle the CPU (reduce the number of CPU processing cycles) in order

to cool the CPU down to a safe operating temperature. Once at a safe operating

temperature, the CPU will continue to perform at its peak capacity.



Thermal Monitor 1

Thermal Monitor 1 uses an on-die temperature sensing

circuit in the CPU that can act quickly in response to

thermal issues. This circuit monitors the most active areas

of the CPU-die at all times and will quickly lower the CPU

temperature by throttling the internal CPU clock speed

when the CPU approaches its maximum operating

temperature.
