3. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see
Identifying a part (www.ibm.com/support/knowledgecenter/POWER9/p9haj/sal.htm).
4. 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.
5. 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.
6. Stop the system. For instructions, see Stopping a system (www.ibm.com/support/knowledgecenter/
POWER9/p9haj/crustopsys.htm).
7. Label and disconnect the power cords from the system unit.
See Figure 33 on page 50.
