8 GIGABIT FIBRE CHANNEL COMPLIANT
Data Field Descriptions
Reading the data
The information is accessed through the SCL and SDA connector pins of the mod-
ule. The SFF-8431 Revision 3.1 specication contains all the timing and addressing
information required for accessing the data in the EEPROM.
The device address used to read the Serial ID data is 1010000X(A0h), and the ad-
dress to read the diagnostic data is 1010001X(A2h). Any other device addresses
will be ignored.
MOD_ABS, pin 6 on the transceiver, is connected to Logic 0 (Ground) on the
transceiver.
SCL, pin 5 on the transceiver, is connected to the SCL pin of the EEPROM.
SDA, pin 4 on the transceiver, is connected to the SDA pin of the EEPROM.
The EEPROM Write Protect pin is internally tied to ground with no external access,
allowing write access to the customer-writable eld (bytes 128 – 247 of address
1010001X). Note: address bytes 0 – 127 are not write protected and may cause
diagnostic malfunctions if written over.
Decoding the data
The information stored in the EEPROM, including the organization and the digi-
tal diagnostic information, is dened in the Small Form Factor Committee docu-
ment SFF-8472 Revision 10.3, dated December 1, 2007.
