Environmenta Reportng
Features
The
CSC-ENVM
card
BNVM
not only provides nonvolatile
and Multibus memory
but
it
also
provides
the environmental
monitoring required for
the
chassis This card checks
input
and
exhaust
air temperatures
and
backplane-voltage
levels
If
the ambient
temperature
exceeds
given range
and
threshold or
if
intake airflow
is
restricted or if any
of the voltages
drift away from
the factory
settings
an
error is
detected
and
the
ENYM
shuts
down
all
functions
in
the chassis
The blower
will
continue
to
run
Power
is
returned
by
turning
off
the
main
breaker switch
waiting
20
to
30
seconds and
then turning
on the
main
breaker switch This
is
called toggling
