# Troubleshooting Power Failures

The system's distributed power system is designed to consume low levels of power and dissipate low levels of heat. See System Specifications for specifications of power consumption and heat dissipation. If you suspect a power problem, see Table 9.

Table 9: Causes of Power Failures
