c) Physically verify that the slot you identified is where you want to remove the adapter.
• 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.
d) If you have not yet recorded the PCIe slot details, record the slot number and location of each
adapter that is being removed.
Note: Adapter slots are numbered on the rear of the system.
e) Stop the system. For instructions, see Stopping a system (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/crustopsys.htm).

procedures require the system power to be turned off, ensure that all the power sources to the
system are disconnected.

the system in a service position after you disconnect the power cords, ensure that you unstrap
the fastener.
