The Si3474 EVB base board consists of:
• Status LEDs
• Terminal Blocks for Power
• USB Connector
• AUTO Mode Selection Jumpers
The RJ45 connectors are on a separate board called the POE_BT_CB. The POE_BT_CB also has some jumpers in order to allow
configuration of the RJ45 for either 802.3bt 4-pair port usage or for 802.3at 2-pair port usage.
It is easier to describe the use cases for the USB Connector, Terminal Blocks, AUTO Mode Selection Jumpers and the POE_BT_CB
jumper connections together.
