Preparing the 9040-MR9 system to permanently remove an NVMe U.2 drive
To prepare the system to permanently remove an NVMe U.2 drive, complete the steps in this procedure.
Procedure
1. If applicable, open the rack door at the front of the system.
2. Review the NVMe U.2 drive LED locations.
The NVMe U.2 drive has two LEDs that indicate the following status:
• A power/activity LED (green)
• An error and identify function LED (amber).

3. To prepare the system to permanently remove an NVMe U.2 drive when the system is powered off,
complete the following steps:
a) Activate the identify function. For instructions, see Identifying a part (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/sal.htm).
b) Physically verify that the slot you identified is where you want to install or replace the NVMe U.2
drive.
• Use the blue identify LED on the enclosure to locate the system. Ensure that the serial number of
the system matches the serial number to be serviced.
• Look for a flashing amber LED, which identifies the slot that was selected by using the identify
function.
c) Stop the system. For instructions, see Stopping a system (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/crustopsys.htm).
4. Label and disconnect the power cords from the system unit as shown in the following figure.
Notes:
• This system might be equipped with two or more power supplies. If the removing and replacing
procedures require the system power to be turned off, ensure that all power sources to the system
are disconnected.
