unlock the next memory cartridge.
2. Repeat step 1 with memory cartridges 2, 3, 4, and 5.
Memory cartridges 2, 3, and 4 will not come online unless their memory
configurations match that of cartridge 1.
After cartridge 5 is online, the newly added memory can be made available to the
operating system. By default, the additional memory is made available to the system
immediately after memory cartridge 5 comes online.
IMPORTANT: Do not unlock any of the memory cartridges while one or all of the memory
cartridges are rebuilding.
All of the DIMM status LEDs should turn off when the upgrade is complete.
All five memory cartridge power LEDs will blink as the memory is made available to
the operating system. This process is complete when all five memory cartridge power
LEDs stop blinking and illuminate solid green.
The hot-upgrade is now complete and you can resume normal server operation.
