• Provides notification of the DIMM failure via the memory board LEDs, the
front-panel internal health LED, and Insight Manager 7.
This process occurs without intervention or server interruption, and enables you to
replace the degraded DIMM at your convenience during a regularly scheduled
shutdown.
DIMM Installation Requirements
In addition to the DIMM configuration requirements for advanced ECC memory,
observe the following DIMM configuration requirements when installing DIMMs for
online spare memory:
• Memory board slot 1 must be populated.
• Bank D on the memory board in slot 1 is always the online spare bank, even if
two memory boards are installed, and must be populated when the server is
configured for online spare memory.
• DIMMs installed in the online spare bank must be of equal or greater capacity
than each of those in the remaining banks on both memory boards.
IMPORTANT: If any of the above requirements is not met, the system automatically switches
to advanced ECC memory and displays an error message during POST.
