Service
NVRAM Failure
There is a mismatch between controller
EEPROM and mirror.
• 950.00 through 950.29 codes—
Mismatch between controller and
mirror.
• 950.30 through 950.60 codes—
Mismatch between secure and
controller.

Service
NVRAM Failure
Mismatch between controller EEPROM
and mirror.
• 951.00 through 951.29 codes—
Mismatch between controller and
mirror.
• 951.30 through 951.60—Mismatch
between secure and controller.

Service
NVRAM Failure
A recoverable MVRAM Cyclic
Redundancy Check (CRC) error
occurred. “
n
” is the offset at which the
error occurred.
Performing a POR will clear this error.

Code CRC <
loc
>
The Code ROM or NAND flash failed
the Cyclic Redundancy Check (CRC)
check or the NAND experienced an
uncorrectible multi-bit failure. “<
loc
>”
indicates the source of the failure and
has one of the following values:
•
CRC Failure
: The source is a
failing package indicated by P
n
where “
n
” is the package number.
This error could occur on a
controller with ROM or NAND flash
and could occur as a result of the
CRC check done when the
machine is powered on. The range
of package numbers is from 0 to
15.
•
Error Correction Code (ECC)
Failure
: The source is a failing
page indicated by B
n
where “
n
” is
the page number. This error occurs
only if a multi-bit failure is detected
during the ECC execution. Single
bit failures will be corrected
automatically and will not result in a
service error. The range of page
numbers is from 0 to 1023.
956.00 Service
RIP board
RIP board failure. Processor failure. Replace the RIP board. Go to
“RIP board
removal” on page 4-19
.
956.01 Service
RIP board
Processor over temperature.
957.

Service
RIP board
RIP board failure. ASIC failure.
