22. nts The ethernet address is pre programmed at the factory and is stored in the on board serial EEPROM The following describes the ethernet address assignment To provide a unique ethernet address for all IQ modules with Ethernet ports an algorithm has been established that combines the IQ module number the port number and the board s serial number The Ethernet address is a six byte number The first three bytes are assigned to Cyclone Microsystems and are fixed at 00 80 4D The last three bytes are broken into three binary fields b XXXX XXXX YYZZZZZZZZZZZZZ The first binary field XXXX XXXX is the Module ID in Hex The SCSI Ethernet IQ Module ID is 73 converted 49 The second binary field YY is the port number For the SCSI Ethernet IQ Module there are two ethernet ports E Net Port A YY 00 E Net Port B YY 01 The third binary field ZZ ZZZZ ZZZZ ZZZZ is the modules serial number converted to hex For example if the module serial number is 1234 then 1234d 4D2 ZZ ZZZZ ZZZZ ZZZZ 00 0100 1101 0010 The complete ethernet address for an SCSI Ethernet IQ Module with serial number 1234 would be E Net Port A 00 80 4D 44 04 D2 E Net Port B 00 80 4D 49 44 D2 SCSI Ethernet IQ Module Board Manual Note Programming Information SCSI Ports This section defines specific setup requirements for the SYM53C875 processors to ensure proper operation of the SCSI Ethernet IQ Module To use Ultra SCSI capabil
