14. If you did not meet the criteria to activate the PCIe link with the system power on, or you want to
activate the link when the system power is turned off, complete the following steps:
a) Record the current date and time. You need it when you power on the system when you are
checking for serviceable events.
b) If the system is not already powered off, turn off the system.
To stop the system, see Stopping a system (www.ibm.com/support/knowledgecenter/POWER9/
p9haj/crustopsys.htm).
15. To connect the expansion drawer cables to the PCIe3 cable adapter ports on the host system and to
a PCIe3 6-slot fanout module on the EMX0 PCIe3 expansion drawer, complete the following steps:
a) Determine the first expansion drawer cable that you connect. It is the cable that is located near
connector T1 on the PCIe3 cable adapter in the host system that you recorded earlier
b) Remove the protective cover from the connector on the expansion drawer cable.
1) Hold the cable housing (B) on the short edges with the index finger and thumb on one hand.
2) Then, grasping the cover on the long edge (A) with the index finger and thumb on your other
hand, pull off the protective cover as shown in the following figure.
Note: Keep your fingers close to the closed end of the protective cover.

c) Connect the expansion drawer cable into the T1 connector on the PCIe3 cable adapter in the host
system.
d) Remove the protective cover and connect the cable that is located near connector T2 on the
PCIe3 cable adapter in the host system.
e) Remove the protective cover and connect the other end of the expansion drawer cable that is
located near connector T1 on the PCIe3 6-slot fanout module in the EMX0 PCIe3 expansion
drawer.
f) Remove the protective cover and connect the other end of the expansion drawer cable that is
located near connector T2 on the PCIe3 6-slot fanout module in the EMX0 PCIe3 expansion
drawer.
