Checkpoint
codes
(trained
service
technicians
only)
A
checkpoint
code
identifies
the
check
that
was
occurring
when
the
server
stopped;
it
does
not
provide
error
codes
or
suggest
replacement
components.
Checkpoint
codes
are
shown
on
the
checkpoint
display,
which
is
on
the
I/O
board.
By
using
the
checkpoint
display,
you
do
not
have
to
wait
for
the
video
to
initialize
each
time
you
restart
the
server.
There
are
two
types
of
checkpoint
codes:
CPLD
hardware
checkpoint
codes
and
BIOS
checkpoint
codes.
The
BIOS
checkpoint
codes
might
change
when
the
BIOS
code
is
updated.

codes
