Preparing Your System For Operation After Connecting An Emx0 Pcie3 Expansion Drawer To Your System - IBM EMX0 PCIe Gen3 Installing

i) If you are not using an HMC, power on the system to running state by choosing one of the
following options:
• Power on one or more logical partitions. For instructions, see Starting a system or logical
partition (http://www.ibm.com/support/knowledgecenter/POWER9/p9haj/crustart.htm).
Notes:
– If you start a partition while the system is in the standby state, the system changes from the
standby state into the operating or running state.
– This option is only available if you have an HMC.
• Power off the system and then power it back on. For instructions, see Stopping a system or
logical partition (http://www.ibm.com/support/knowledgecenter/POWER9/p9haj/crustop.htm)
and Starting a system or logical partition (http://www.ibm.com/support/knowledgecenter/
POWER9/p9haj/crustart.htm).
24. You have completed the steps to route, connect, and activate the PCIe link for the expansion drawer
cable.
Preparing your system for operation after connecting an EMX0 PCIe3 expansion drawer
to your system
To prepare your system for operation, complete the steps in this procedure.
Procedure
1. If the system has a rear door, close or replace it.
2. Verify that the system or logical partition recognized the EMX0 PCIe3 expansion drawer.
Verify the installed part. For instructions, see Verifying the installed part (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/pxhaj_hsmverify.htm).
3. If the system has logical partitions, you can now assign I/O slots in the expansion drawer that was
added to the logical partitions.
For instructions, see Managing physical I/O devices and slots dynamically (http://www.ibm.com/
support/knowledgecenter/POWER9/p9hat/p9hat_dlpariopp6.htm).
4. You have completed the steps to install an EMX0 PCIe3 expansion drawer.
If you were directed here from another procedure, return to that procedure now.
