Table 5. EEPROM Serial ID Memory Contents - Address A2h, Byte 110
Notes:
1. Bit 6 is logic OR’d with the SFP Tx_Disable input pin 3 ... either asserted will disable the SFP transmitter.
2. AFCT-5745Z does not respond to state changes on Rate Select Input Pin. It is internally hardwired to full bandwidth.
