It could be a PS card or
a
PS pluggable
module failure.
-If the failing font is known, use Figure
6-14 to isolate the failing module.
-Otherwise order a neN F2 logic card for
the PS2 feature, and five new pluggable
modules as well.
-Fit the new modules to the new card.
-Remove the jumper on the card if it is
present.
-Temporarily install the new F2 card and
