IPLing Stand-Alone Services

This topic lists the steps to IPL the Stand-Alone Services program. The programming status word (PSW) wait-state codes (encountered during Stand-Alone Services processing) are found in Interpreting wait-state codes. An example of the Stand-Alone Services system IPL is included in IPL example.

To IPL from the Stand-Alone Services core image (created with the BUILDSA command), proceed as follows:

Load the Stand-Alone Services Program.
Load Stand-Alone Services from the processor’s IPL console by specifying the IPL address for the device (card, tape, or DASD) that contains the IPL-able core image and then, by performing a Load Clear operation (also referred to as an IPL Clear).
Select the Operator Console.
When the Stand-Alone Services program has finished loading, one of the following conditions exist:
- If the Stand-Alone Services core image was created without specifying the OPERCNSL keyword, then the processor enters a wait-state with the rightmost bytes of the PSW containing "FFFFFF". Press the Enter key on the operator console you are using. The first interrupt presented is expected to be a console and is treated as such.
- If the Stand-Alone Services core image was created with the OPERCNSL keyword specified, then Stand-Alone Services attempts to use the device address specified by OPERCNSL as the operator console, rather than waiting for the first interrupt. See Running stand-alone services with a predefined console for more information.
Specify the Input Device.
After the operator console is identified, the following message is displayed:
```
 ADRY005E  DEFINE INPUT DEVICE, REPLY ‘dddd,ccuu’ or ‘CONSOLE’
```
To specify the operator console as the input device, enter CONSOLE or a null line. To specify a different device type, enter dddd,ccuu, where dddd is either the device type or card, and ccuu is the unit address. For example, to select a 3505 card reader at address 502, enter:
```
    card,502
```
The input device can be one of the supported console devices or a card reader device.
Specify the Message Output Device.
After the input device is identified, the following message is displayed:
```
 ADRY006E  DEFINE OUTPUT DEVICE, REPLY ‘dddd,ccuu’ or ‘CONSOLE’
```
To specify the operator console as the output device for operator communication, enter CONSOLE or a null line. To specify a different device type, enter dddd,ccuu, where dddd is either the device type or prnt, and ccuu is the unit address. For example, to select a 3800 print subsystem at address 510, enter:
```
    prnt,510
```
The output device can be a supported console device or a supported printer device.
Specify the correct date and time, if needed.
Stand-Alone Services automatically picks up the time and date from the processor’s time-of-day (TOD) clock, usually in the Greenwich Mean Time (GMT) format. When the TOD clock is incorrect or is not set, the following message is displayed:
```
 ADRY015E  SUPPLY TODAY’S DATE, REPLY ‘MM/DD/YY’
```
When you have entered the correct date in the format indicated, the following message is displayed:
```
 ADRY016E  SUPPLY TIME OF DAY, REPLY ‘HH:MM:SS’
```
Enter the correct time in the format indicated. If you press Enter without specifying a date or time, the value is set to zero.

At this point the IPL is complete. You can now enter Stand-Alone Services commands from the specified input device. Multiple commands can be entered without requiring a re-IPL of the Stand-Alone Services program.

Note: Operator messages such as ADRY003D are sent to the operator console, not the specified output device.
