This is an actual alert to IBM field engineers that went out
to all IBM Branch offices. The person who wrote it was very
serious. The rest of us may find it rather funny.
Abstract: Mouse Balls available as FRU.
Mouse balls are now available as FRU (Field Replaceable Units).
Therefore, if a mouse fails to operate or should it perform
erratically, it may need a ball replacement. Because of the
delicate nature of this procedure, replacement of mouse balls
should only be attempted by properly trained personnel. Before
proceeding, determine the type of mouse balls by examining the
underside of the mouse. Domestic Balls will be larger and
harder than foreign balls. Ball removal procedures differ
depending upon the manufacturer of the mouse.
Domestic balls are replaced using the twist-off method. Mouse balls are
not usually static sensitive. However, excessive handling can result in
sudden discharge. Upon completion of ball replacement, the mouse may be
used immediately. It is recommended that each replacer have a pair of
spare balls for maintaining optimum customer satisfaction and that any
customer missing his balls should suspect local personnel of
removing these necessary items.
