Hi Guys,

This also goes back around 25 years when in the space of two weeks I was involved in two power switch incidents in the space of two weeks. The first incident was on a trading floor in the Minories in London, on a Data General Aviion system an 8550 I think. Anyway, while getting ready for a very short outage on the system - I found out that the Grey import that this company had sneaked onto the contract had a power interlock on one of the Zeus fasteners on the rear panel of the system.

The other incident was much more humerous from my perspective at least.

Whilst going past a comms room in a fairly deserted part of the building, my attention was attracted by shouts for help. I went into the comms room to see one of the software developers perched cross legged on a swivel chair infront of a big (for it's time) Data General Clariion Disk Array (60 Bay I think), when I asked what the problem was I did have to struggle to keep a straigh face.

The developer had spun round on his chair and the pointed toe of his shoe had depressed the power button on the array, he had had the common sense to not move so the button hadn't popped out and dropped the array power - but he'd been there for about an hour and was now suffering cramps.

Fortunately there was enough space to get a finger in and hold the button down, whilst we got a clean shutdown of the application and the system. However the developer had to be helped out of the swivel chair by others as we just left him there while verything was brought down.

The Clariion power button was modified with a Domestos bottle top, which had a hole cut in it being Araldited over the offending button.

Ah the good old days.

Regards

SYSMON_PSWITCH(9)					   BSD Kernel Developer's Manual					 SYSMON_PSWITCH(9)

NAME
sysmon_pswitch -- framework for power switches SYNOPSIS
#include <dev/sysmon/sysmonvar.h> int sysmon_pswitch_register(struct sysmon_pswitch *smpsw); void sysmon_pswitch_unregister(struct sysmon_pswitch *smpsw); void sysmon_pswitch_event(struct sysmon_pswitch *smpsw, int event); DESCRIPTION
The machine-independent sysmon_pswitch provides a framework for power management. The interface has been largely superceded by the pmf(9) framework, but sysmon_pswitch is still used to manage power switches as well as related mechanical adapters and buttons. These are encapsu- lated in the following structure: struct sysmon_pswitch { const char *smpsw_name; /* power switch name */ int smpsw_type; /* power switch type */ LIST_ENTRY(sysmon_pswitch) smpsw_list; }; Unsurprisingly, smpsw_name specifies the name of the power switch and smpsw_type defines the type of it. The following types are defined: PSWITCH_TYPE_POWER PSWITCH_TYPE_SLEEP PSWITCH_TYPE_LID PSWITCH_TYPE_RESET PSWITCH_TYPE_ACADAPTER PSWITCH_TYPE_HOTKEY If the type is PSWITCH_TYPE_HOTKEY, there are few predefined names that can be used for smpsw_name: PSWITCH_HK_DISPLAY_CYCLE display-cycle PSWITCH_HK_LOCK_SCREEN lock-screen PSWITCH_HK_BATTERY_INFO battery-info PSWITCH_HK_EJECT_BUTTON eject-button PSWITCH_HK_ZOOM_BUTTON zoom-button PSWITCH_HK_VENDOR_BUTTON vendor-button Once a power switch event has been proceeded, sysmon_pswitch will inform the user space powerd(8), which will possibly execute a script matching the type of the power switch. FUNCTIONS
After the sysmon_pswitch structure has been initialized, a new power switch device can be registered by using sysmon_pswitch_register(). The device can be detached from the framework by sysmon_pswitch_unregister(). The sysmon_pswitch_event() is used to signal a new power switch event. There are two possibilities for the value of event: PSWITCH_EVENT_PRESSED A button has been pressed, the lid has been closed, the AC adapter is off, etc. PSWITCH_EVENT_RELEASED A button has been released, the lid is open, the AC adapter is on, etc. The corresponding events in powerd(8) are pressed and released.
