STARTUP AND CONFIGURATION
3.1
Startup
After 3.3 Volt power is applied, the SFP module starts up and self-configures the
88Q2112_A2 transceiver by MDIO interface. This lasts 100ms. Do not apply any I2C
activity on the bus during this time!
3.2
Self-Configuration
The SFP Module configures itself to 1000BASE-T1 after power up. Master-/Slave
Configuration is done according to the DIP switch on the bottom of the device.
To reconfigure the DIP switch the lock has to be opened (see pictures).
ON/right = as Master
OFF/ left = as Slave
