Environmental Monitoring

The Netra CP3010 board uses an intelligent fault detection environmental
monitoring system that increases uptime and manageability of the board. Through
an Intelligent Platform Management Controller (IPMC) and system management
software, the Netra CP3010 board monitors voltage, temperature, and power on
sensors.
