Power and Environmental Management
Managing power and environmental factors.
Power and Environmental Management, as covered in CompTIA A+, focuses on efficient operation of computing resources while considering energy consumption and environmental impacts. Power Management: Modern devices include features to reduce electricity usage when not at full capacity. This includes sleep/hibernate modes, where systems store current state to memory or disk and enter low-power states. Wake-on-LAN allows remote power-on capabilities for maintenance. Power plans (Balanced, Power Saver, High Performance) let users customize performance versus energy efficiency. ACPI (Advanced Configuration and Power Interface) enables OS-hardware communication for power states (S0-S5). Modern CPUs utilize dynamic voltage/frequency scaling to adjust processing power based on workload. Environmental Management: IT professionals must consider proper placement of equipment for heat dissipation. Server rooms require controlled temperature (typically 68-75°F/20-24°C) and humidity (40-60%). Proper airflow patterns prevent hot spots, with cold air intake and hot air exhaust separation. UPS (Uninterruptible Power Supply) systems protect against power fluctuations and provide runtime during outages. Surge protectors safeguard against voltage spikes. Best Practices: Implementing power scheduling to automatically shut down systems during non-business hours. Using energy-efficient hardware with ENERGY STAR certification. Enabling power management features across organizational devices. Properly recycling electronic waste according to regulations. Virtualization to consolidate workloads onto fewer physical machines. Benefits include reduced electricity costs, extended hardware lifespan through proper environmental controls, decreased carbon footprint, and compliance with green initiatives and regulations. CompTIA A+ emphasizes these concepts as fundamental knowledge for IT professionals.
