Is there information about Aix logical and physical location codes?
Is there information about Aix logical and physical location codes?
Information is available about the following codes: AIX logical location codes can still be seen and supported under various AIX commands and functions. However, the Diagnostic screens and menus display physical location codes for resources when running versions 5.2.0 and later. For these systems, refer to Physical Location Codes.
What do you need to know about Aix boot process?
I. The boot process in AIX As a system administrator you should have a general understanding of theboot process. This knowledge is useful to solve problems that can prevent asystem from booting properly. These problems can be both software or hardware.We also recommend that you be familiar with the hardware configuration of your system.
What is AIX 5L software ROS?
Software ROS is AIX 5L information created based on machine type and is responsible for completing machine preparation to enable it to start AIX 5L kernel. A complete list of files that are part of the BLV can be obtained from directory/usr/lib/boot.
How much memory is available to load the AIX kernel?
Less than 2 MB of good memory are available to load the AIX kernel. FCS SCSI protocol device is being configured (32 bits). Virtual SCSI devices being configured.
What are led blink codes 1 – 8?
LEDs 1 – 8 are used for the LED blink codes. These 8 LEDs are logically separated into two 4-digit segments. Each 4-digit segment represents a hexadecimal digit. LEDs 5 – 8 make up the most significant hex digit and LEDs 1 – 4 make up the least significant hex digit.
How many LEDs can be interfaced with the microcontroller?
The microcontroller provides a 5V output on a port pin, hence to limit the current to 10mA a resistance of 470Ω is used in series with the LED. 8 LEDs are interfaced to PORT2 of the schematic as shown. You may wish to connect to any of the other ports as well.
Where do the LEDs connect to the 8051 microcontroller?
The LEDs are connected to any of the four ports of the 8051 microcontroller. Schematic Diagram The schematic can be divided in two logical parts for the micrcontroller, the minimum connections required are discussed in the first section, which will be common for any interface.
