4048-1xx Service error codes (9xx) (continued) Error Description 955 Code CRC 956 Controller card 957 ASIC failure 958 NAND failure 959 SRAM failure 960 RAM soldered on the card is bad 961 RAM in slot 1 is bad Action Replace the controller card. Where = CRC Failure or ECC Failure on the controller card. Error codes 956, 957, and 959 are controller card failures. Perform a power on reset (POR). If this does not fix the problem, replace the controller card. Error codes 956, 957, and 959 are controller card failures. Perform a power on reset (POR). If this does not fix the problem, replace the controller card. Before proceeding, perform a power on reset (POR) to see if the ECC error correction code can reflash NAND. If this does not fix the problem, replace the controller card. Error codes 956, 957, and 959 are controller card failures. Perform a power on reset (POR). If this does not fix the problem, replace the controller card. Indicates a DRAM Memory Error on the controller card. Replace the controller card. If another SDRAM memory DIMM is available, turn the power off and switch the DIMM. If the memory card now works correctly, replace the failing DIMM. If this does not fix the problem, replace the controller card. If another DIMM is not available, replace the memory option first and then the controller card if necessary. Diagnostic information 2-9
