Page 13: Chapter 2. Getting Started
Chapter 2. Getting Started OVERVIEW This chapter provides a quick start guide for using the KSZ8895 EDS2 Daughter Card. The SAM9x75 Curiosity (Rev 5) serves as the host board. Refer to the SAM9x75 Curi- osity User's Guide for the correct jumper configuration. - Page 14 KSZ8895 EDS2 Daughter Card User Guide Perform the following steps to install the KSZ8895 EDS2 Daughter Card in the SOD- IMM EDS2 connector: 1. Verify that the host board power is OFF. 2. Verify if the SW1 slide switch is set as shown in Figure 2-2.
- Page 15 Connecting or disconnecting Ethernet cables after the board is powered is NOT recom- mended as the board fingers could be disconnected from the SODIMM receptacle and leave the board in an inconsistent state or even cause damage to the board. 2025 Microchip Technology Inc. and its subsidiaries DS50003881A-page 15...
