Installing Hardware Options, Hot-Plug
To replace DIMMs:
1. Remove the memory cartridge by following the procedure in the “Removing the
Memory Cartridge” section of this chapter.
CAUTION: Do not remove a memory cartridge if the cartridge power LED is
blinking or is solid green. The system will halt.
If the cartridge power LED has not turned off after unlocking the
cartridge, then one of the following conditions exists:
• Another cartridge is either powered down or removed.
• Another cartridge in the system has errors.
2. Remove the failed DIMM.
3. Install a working DIMM by following the procedure in the “Installing DIMMs in
the Memory Cartridge” section of this chapter.
Installed DIMMs should be of the same speed, type, and size. They should have
the same HP part number (for example 123456-12x, where x is not required to
match).
CAUTION: When handling a memory module, be careful not to touch any of the
contacts. Doing so may damage the module.
IMPORTANT: Be sure DIMMs are installed in the proper orientation. The DIMMs are
keyed to ensure they are installed correctly in the memory socket.
4. The system will rebuild and verify the data on the DIMMs in the memory
cartridge while the cartridge power LEDs are blinking. This process is complete
when the cartridge power LED is illuminated solid green, indicating that the
cartridge is online.
5. Continue with normal server operation.
