The
following
sections discuss reading and
interpreting the
LED
indicators
on
interface
and
controller cards
CSC-1R and CSC-2R Token
Ring
Cards LED
Ondicators
Along the
front
edge of the
CSC-1R and
CSC-2R
card
are
ten
status
LEDs
nine red
and one green
The
order of the
LEDs
is
left to right
when
looking at the
front edge of
the
card See
Figure
B-i
Although
only the
CSC-1R
is
shown
both
the
CSC-1R
and
CSC-2R
cards
have
the same
LED
configuration
Card-numbering
switches
oooooooooo
The
red
LED
on
the
far left
end
of the
bank
of
LEDs
is the
Power-On
LED
No
The
next
LED
is
the green Processor
LED
No
The
remaining eight
LEDs
through
10
are
all
red At system
boot these eight
LEDs
will change
state to
indicate
that
the
CSC-2R
card
is being initialized
The
seven
initialization states
of
LEDs
through
10
are
shown
in Table
B-i
In the
first
initialization
state all eight status
LEDs
through
10
are
on
During
the next four states
LEDs
through
10
will
be on
while
LEDs
through
consecutively
will turn
on
then off States
and
will
indicate
successful
initialization
The
first
seven
LED
states display consecutively
at
system
boot
If problem occurs
during
this
initialization
the
state that the
LEDs
were
in
when
the problem
occurred
will flash on
and
off
When
the port
inserts onto
the ring
LEDs
through
10
will flash series of patterns too
fast to
see
Following this
LEDs
through
iO
will
strobe back and
forth
to
indicate correct operation The
speed
of
this
strobing is
in inverse proportion
to
the
volume
of data
traffic
the
heavier the
traffic
the
slower the strobing
and
so forth Either
way the
strobing of these
LEDs
is
the key indicator for the
proper operation of the
CSC-1R
and
CSC-2R
