To access the DIMMs in the server, you must remove the memory cartridge. The Hot

Removing the Memory Cartridge
To remove a memory cartridge from the ProLiant DL740 server:
1. Slide the server out of the rack and open the top access panels.
2. Unlock the memory cartridge by sliding the cartridge lock (1) open.
IMPORTANT: If the memory cartridge is not required for continued operation (with at
least four other memory cartridges installed, online, and error free), then the memory
cartridge power LED will turn off.
IMPORTANT: If the cartridge is required for continued operation, an audible caution
alarm will sound and the memory cartridge attention LED will blink until the cartridge is
locked again.
3. Be sure that the cartridge power LED is off.
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
4. Lift the cartridge lever upward (2) to release the memory cartridge.
5. Pull the cartridge out (3) of the host module.
