Details advanced Power over Ethernet capabilities, including Power over Ethernet Boost, Fast Power over Ethernet, Perpetual Power over Ethernet, and four-pair Power over Ethernet, and guides configuration to optimize startup behavior, maintain uninterrupted power during reloads, and maximize available power for connected devices.
PoE boost
Explains how IE3100 PoE uses an integrated boost power supply to create 54V from 12V or 24V inputs, passes through 52.5V or greater inputs, and adjusts the PoE power budget based on input voltage and platform limits.
Fast PoE and perpetual PoE
Describes Fast PoE and perpetual PoE, which restore or preserve power during system boot. Explains CLI-based enablement and summarizes behavior for resets, warm reboots, firmware validation, and power budget checks, with a configuration task referenced in this guide.
Configure perpetual PoE and fast PoE
Configure perpetual PoE and Fast PoE on an interface to keep powered devices on during reload and allow rapid start after power cycles. Configure using CLI commands in privileged and global configuration modes.
Four-pair power over Ethernet
Provides an overview of four-pair Power over Ethernet (4PPoE), IEEE 802.3bt Type 4 capabilities, and IE3100 POE support with boost mode, including budgets, ports, and SKU mapping information.
