Cabling the server with an ASCII terminal
If you are not creating logical partitions, you can use an ASCII terminal to manage a server that is running
the AIX, Linux, or VIOS operating systems. From the ASCII terminal, you can access the Advanced System
Management Interface (ASMI) to complete more installation tasks.
About this task
The ASCII terminal is connected to the server through a serial link. The ASCII interface to the ASMI
provides a subset of the web interface functions. The ASCII terminal for the ASMI interface is available
only when the system is in the standby state. It is not available during the initial program load (IPL) or run
time.
Note: If you are using a serial connection to the ASMI terminal, you must use a conversion cable. This
cable (part number 46K5108) is used to convert the ASCII terminal 9-pin Dshell connector to an RJ45
serial port connector on the system. For information about the locations of the connectors on the system,
see Part locations and location codes (http://www.ibm.com/support/knowledgecenter/POWER9/p9ecs/
p9ecs_locations.htm).
To cable an ASCII terminal to the server, complete the following steps:
Procedure
1. Using a serial cable that is equipped with a null modem, connect the ASCII terminal to the serial port
on the rear of the server.
2. Complete the following steps:
a. Plug the power cord into the power supply.
Note: If present, remove and discard any plug that covers the ports on the rear of the system. The
port covers ensure that you are reminded about resetting the Administrator password of your
managed system after the initial program load (IPL) completes.
b. Plug the system power cords and the power cords for any other attached devices into the power
source.
c. If your system uses a power distribution unit (PDU), complete the following steps:
1) Connect the system power cords from the server and I/O drawers to the PDU with an IEC 320
type receptacle.
2) Attach the PDU input power cord and plug it into the power source.
3) If your system uses two PDUs for redundancy, complete the following steps:
• If your system has two power supplies, attach one power supply to each of the two PDUs.
• If your system has four power supplies, plug E1 and E2 to PDU A and E3 and E4 to PDU B.
Note: Confirm that the system is in standby mode. The green power status indicator on the front
control panel 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.
3. Wait for the green light on the control panel to start flashing.
4. Ensure that your ASCII terminal is set to the following general attributes.
These attributes are the default settings for the diagnostic programs. Be sure that your terminal is set
according to these attributes before proceeding to the next step.
