v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 4, "Parts listing," on page 41 to determine which components are CRUs and which components
are FRUs.

Error Code Type
0x800B0100 Error
0x800B0300 Warning
Error Message
Memory device 0 (Bckup Mem
Status) is not redundant
Memory device 0 (Bckup Mem
Status) is not redundant and
operational with minimal
resources
Action
1. Check the event logs for other memory errors that
might occur (see "Error logs" on page 103).
2. Reseat all of the memory modules in the blade
server (see "Removing a memory module" on
page 64 and "Installing a memory module" on
page 65).
3. Make sure all of the memory is enabled in the
Setup utility (see "Using the Setup utility" on
page 21). Notice which memory modules are
disabled before continuing to the next step.
4. If the error still occurs, replace the memory
modules that were disabled in the Setup utility
(see "Removing a memory module" on page 64
and "Installing a memory module" on page 65).
5. (Trained service technician only) If the error still
occurs, replace the microprocessor that controls
the failing memory module.
Note: DIMM sockets one through six are
controlled by the first microprocessor and DIMM
sockets seven through twelve are controlled by
the second microprocessor. See "Removing a
microprocessor and heat sink" on page 90 and
"Installing a microprocessor and heat sink" on
page 94.
