The following diagram shows one AC feed (3) connected to one PDU (1). This PDU splits power
between power supplies 1 (5) and 2 (6).
Figure 26. Cabling for power source redundancy: AC feed #1
The following diagram shows the second AC feed (4) connected to the second PDU (2). This
second PDU then splits power between power supplies 3 (7) and 4 (8).

2) Attach the PDU input power cord and plug it into the power source.
3) Confirm that the system is in standby mode. The green power status indicator on the front
control window is flashing, and the dc out indicator lights on the power supplies are flashing. If
none of the indicators are flashing, check the power cord connections.
2. If you have an expansion unit that you need to install, install it now. For information about connecting
enclosures and expansion units, see Enclosures and expansion units (http://www.ibm.com/support/

Completing the server setup
Learn about the tasks you must complete to set up your managed system.
Select from the following options:
• "Completing the server setup by using an HMC" on page 30
• "Completing the server setup without using an HMC" on page 32
Completing the server setup by using an HMC
Perform these tasks to complete the server setup by using a Hardware Management Console (HMC). You
can also begin to use virtualization to consolidate multiple workloads onto fewer systems to increase
server use, and to reduce cost.
Before you begin
To manage POWER9(tm) processor-based systems, the HMC must be at version 9 release 9.2.0, or later.
About this task
To complete the server setup by using an HMC, complete the following steps:
Note: After power has been applied to the system, wait for 10 - 15 minutes for the connection to the HMC
to be established.
Procedure
1. Change the managed system passwords by completing the following steps:
For more information about setting passwords for the managed system by using the HMC, see Setting
passwords for the managed system (http://www.ibm.com/support/knowledgecenter/POWER9/
p9hai/p9hai_setpassword_enh.htm).
2. Update the time of day on the managed system by using the Advanced System Management
Interface (ASMI).
To access ASMI by using the HMC, complete the following steps:
a. In the contents area, select the managed system.
b. Select Actions > View All Actions > Launch Advanced System Management (ASM).
c. Log on to the ASMI by using the administrator user ID and password.
