TP-Link PoE switches are powered via PoE itself and do not require an additional AC or DC adapter, with power budgets depending on the PoE standard used.

PoE Power Supply Overview

TP-Link PoE switches, such as the TL-SG1005P, are designed to deliver both data and electrical power over a single Ethernet cable to connected devices like IP cameras, access points, and VoIP phones, eliminating the need for separate power adapters or outlets for each device . These switches rely on PoE input from an upstream PoE++ switch or injector and do not support direct AC or DC power supply .

PoE Standards and Power Budget

• 802.3af (PoE): Provides up to 15.4 W per port
• 802.3at (PoE+): Provides up to 30 W per port
• 802.3bt Type 3 (PoE++): Provides up to 60 W per port
• 802.3bt Type 4: Provides up to 90 W per port For example, the TL-SG1005P switch has 4 PoE+ output ports and a total PoE budget of 65–66 W, depending on the standard used . The switch automatically detects the required power for each connected device and protects non-PoE devices from damage.

Deployment Features

• Plug and Play: No configuration is required; devices receive power automatically .
• PoE Auto Recovery: The switch can automatically reboot unresponsive powered devices, ensuring stable operation .
• Extend Mode: PoE transmission distance can reach up to 250 m (820 ft) at reduced speeds, useful for large-area IP camera deployments .
• Fanless Design: Ensures silent operation, suitable for home or office environments .

Practical Considerations

• Ensure the upstream PoE source (switch or injector) can supply sufficient power to meet the total PoE budget of the switch.
• Use high-quality Ethernet cables to maintain power delivery over longer distances.
• For non-PoE devices, a PoE splitter like the TL-POE10R can convert PoE to standard DC voltages (5V, 9V, 12V) to power devices that do not support PoE . In summary, TP-Link PoE switches are powered entirely via PoE input, with no need for additional adapters, and provide flexible, reliable power delivery to multiple devices while simplifying network deployment and reducing cabling requirements .
