Planning Guidelines

PoE Standards: 802.3af (15.4W), 802.3at/PoE+ (30W), 802.3bt Type 3 (60W), 802.3bt Type 4 (100W). Devices require ports matching or exceeding their power standard.

Port Allocation: This tool validates that switches have enough ports of the correct PoE standard. A PoE++ device will NOT power on with a PoE/PoE+ port, even if total wattage seems sufficient.

Buffer Recommendations: Add 20-30% buffer to PoE budget to account for power spikes, future expansion, and efficiency losses. Never run switches at 100% PoE capacity.

UPS Sizing: Target 15-30 minutes of runtime for graceful shutdown. Critical infrastructure should have redundant UPS systems. Consider generator backup for extended outages.
