Instructions and descriptions for control panel functions
Control panel functions can be classified into three categories: normal functions, extended functions, and low-level debug functions. The remote control panel and virtual control panel can perform most of these functions. The physical control panel can perform all of them.
- Normal control panel functions
- Normal control panel functions are the most often performed functions, such as displaying IPL speed and forcing the system to perform an IPL. They also include functions such as forcing DST and forcing a main storage dump. These functions are 01 through 49.
- Extended control panel functions
- Extended control panel functions are performed less often. Only service representatives can perform these functions. Extended functions are 50 through 70.
- Low-level debug panel functions
- These are functions 57 through 70. They are performed only by service representatives.
The examples in the following topics show control panels with a 4-word (32 character) display. Control panels with a 1-word (8 character) display only show the first word (8 characters) of each function.
- Normal control panel functions
These instructions show how to use normal control panel functions 01 through 49. Functions 21 through 49 are available when you select the Manual mode.
- Extended control panel functions
The system enables service functions 50 through 70 when you select manual mode and enter function 25 (service switch 1), then function 26 (service switch 2). You use subfunctions with Functions 51 and 57 through 64.
- Low-level debug panel functions 57 through 70
You can enable these functions by selecting Manual mode and selecting functions 25 and 26.
