Current usage for the serial port connectors are as follows:
Serial Port Number Location Examples of Applicable Usage
Serial Port 1 (S1
Front) Operator Panel Service Agent, PDA system management applications (for example,
handheld devices, laptop systems), Service Processor menus, ASCII
terminal for the operating system console, and modems
Serial Port 1 (S1
Rear) Rear of the System Service Processor menus, Service Agent, PDA system management
applications (interface cable required), ASCII terminal for the
operating system console, and modems
Serial Port 2 (S2) Rear of the System Service Processor menus, HACMP, ASCII terminal for the operating
system console, and modems
Serial Port 3 (S3) Rear of the System HACMP, UPS (uninterruptible power supply), ASCII terminal for the
operating system console, and modems
Notes:
1. Serial port 1 is never used to run HACMP or attach a UPS. If you are configuring your system to run
HACMP with a UPS attached, you must connect the HACMP cable to serial port 2 and the UPS
cable to serial port 3.
Do not run UPS connected to serial port 2. If you disconnect HACMP, you
must reset the service processor using the pinhole reset switch before running another application.
The service processor pinhole reset switch is located on the operator panel.
2. A modem can be attached to any of the serial ports.
Security Features
On the Model 6C4 and Model 6E4, you can set the following types of passwords to limit access to these
systems:
v
General-access password - set only from the service processor menus. It provides limited access to the
service processor menus and is usually available to all users who are allowed to power on the system.
v
Privileged-access password - Set from the service processor menus or from System Management
Services (SMS) utilities. Used by the system administrator or root user and allows access to all service
processor functions.
Hardware Management Console (HMC)
The Hardware Management Console (HMC) is an optional feature that allows you to manage configuration
and operation of partitions in a system, as well as add and remove hardware without interrupting system
operation.
In this book, a system that is managed by the HMC is referred to as the managed system . The HMC uses
its serial connection to the managed system to perform various functions. The HMC’s main functions
include the following:
v Detecting, reporting, and storing changes in hardware conditions
v
Acting as a service focal point for service representatives to determine an appropriate service strategy
Service representatives use the Service Focal Point application on the HMC to start and end their service
calls. Service Focal Point provides service representatives with serviceable event information, vital product
data (VPD), and diagnostic information.
The HMC is a closed system. Additional applications cannot be loaded on the HMC. All the tasks needed
to maintain the platform, the underlying operating system, and the HMC application code are available by
using the HMC’s management applications.
