step “9” on page 401.
• If the system power is turned on and if the Linux
®
operating system controls the slot, continue with
step “11” on page 402.
6. To prepare the system to install an NVMe 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 identied 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 identies 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).
