5-16 FRU Removal and Replacement

8. Use the EEPROM puller (AMP part no. 821903-1) to remove the EEPROM from

the defective CPU board and from the new CPU board (see Figure 5-13). Insert

the EEPROM from the defective CPU board into the new CPU board, and insert

the new EEPROM into the defective CPU board. When you insert the EEPROMs

make sure that you orient the ﬂat corner of the EEPROM to the ﬂat corner of the

socket, and that the writing on the EEPROM faces up.
