xPower Systems: Cabling your server

Cabling your server
Learn how to cable your server to a console, terminal, or interface, such as the Advanced System
Management Interface (ASMI), to an expansion unit, or to other adapters and peripheral equipment.
To learn more about the consoles, terminals, and interfaces that are available for your server, see the
following descriptions.
Advanced System Management Interface (AIX®, IBM i, and Linux operating systems)
The Advanced System Management Interface (ASMI) is the interface to the service processor on
your system. From the ASMI, you can perform tasks such as changing the firmware power-on
settings, setting the time of day, and entering network configuration parameters. Set up access to
the ASMI if your system cannot be managed by Hardware Management Console (HMC) or a
Systems Director Management Console (SDMC).
Hardware Management Console (AIX, IBM i, and Linux operating systems)
The Hardware Management Console (HMC) is a dedicated workstation that runs integrated
system management software. The HMC manages hardware tasks and configures logical
partitions on managed systems, and acts as a focal point for hardware error detection and
reporting. You can use the HMC to manage models, System p®servers, or the IBM Power
Systems™servers.
Integrated Virtualization Manager (AIX or Linux operating system)
The Integrated Virtualization Manager (IVM) provides a Web-based system-management interface
and a command-line interface that you can use to manage and configure IBM System p servers or
IBM Power Systems servers that run AIX or Linux and use the IBM Virtual I/O Server. On the
managed system, you can create logical partitions, manage the virtual storage and virtual
Ethernet, and view service information related to the server. The Integrated Virtualization
Manager is packaged with the Virtual I/O Server, but it is enabled only on certain platforms and
when no Hardware Management Console (HMC) or Systems Director Management Console
(SDMC) is available.
ASCII terminal (AIX or Linux operating system)
The ASCII terminal is connected to a server running AIX or Linux through a built-in system port.
An ASCII terminal can only be connected to the service processor if the system is not managed
by an HMC or SDMC.
Graphics terminal (AIX or Linux operating system)
The graphics terminal is available to customers who want to attach a graphical user interface
(GUI) to AIX or Linux servers. You can use the graphics terminal with or without the HMC or
SDMC. A graphics terminal can be attached to a managed system (a system connected to an
HMC or SDMC), as well as a stand-alone system (not connected to an HMC or SDMC).
Operations Console (IBM i operating system)
Use the Operations Console to access and control System i®models or IBM Power Systems
servers that are running the IBM i operating system. You can set up the Operations Console if
you plan to manage the IBM i operating system in a partitioned or nonpartitioned environment.
In a partitioned environment, you must also use the HMC or the SDMC to configure, manage,
and maintain your hardware.
Systems Director Management Console (AIX, IBM i, and Linux operating systems)
The Systems Director Management Console (SDMC) is a unified management platform that
manages hardware tasks and configures logical partitions on managed systems. The SDMC also
acts as a focal point for hardware error detection and reporting. You can use the SDMC to
manage System i models, System p servers, or the IBM Power Systems servers. Certain system
firmware levels are required on the managed system to attach an SDMC.
