re question 5:
I'm not sure what you call your class's of extinguishers. But anycase here goes.
Water and wet foam should never be used unless your building is in danger. The results would be shocking. Besides it will ruin you computer, but if itson fire and you in danger of losing the building, then a single computer worth a few thosand is a fair trade off agaist a buiding worth a few million. Besides, where's your backups?
Dry foam (powder) would ruin the computer but at least you won't be shocked.
Gas is the only safe option here, in this country it is class 3. However you must remember that gas (co2, halon, ect.) do not have any cooling qualitys.
re question 6:
according to my NEW RIDERS A+ manual. Do not plug in high power periphal devices such as laser printers should not be pluged into a UPS.
