24-port (PoE 2, 2-pair) power sourcing equipment reference design for multi-port applications
Overview
| Topology | Other Topology |
| IC revision | A |
Description
This reference design showcases a Type-3, 30W, 2-Pair 24-port Ethernet switch for Power over Ethernet (PoE) applications which can send up to 30W per port for IEEE 802.3bt Type 3 applications and up to 60W per port for non-standard applications. Based on the MSP430F523x family, TI's TPS2388x FirmPSE system firmware provides a total system level solution for multi-port applications which reduces time to market and frees-up valuable software resources. This design supports port power management with priority, multiple power supplies, legacy PD detection, field upgradability, UART/I2C communication with the host, and more. TI’s FirmPSE system firmware GUI for this design enables the customization of production level PSE system firmware code with just a few clicks of a button and provides real-time communication to the system. In addition, two of these designs may be cascaded through the edge connectors in order to support up to 48-port PSE systems.
Features
- Configurable GUI and host interface
- Multi-port power managementAbility to cascade two designs through edge connectors to enable 48-port PSE system
- Supports multiple power supplies
- Legacy PD capacitance measurement
Typical applications
- Video recorder
- Campus and branch switches, Edge router
