Power-cord
connector:
Connect
the
power
cord
to
this
connector.
AC
power
LED:
Each
hot-swap
power
supply
has
an
ac
power
LED
and
a
dc
power
LED.
When
the
ac
power
LED
is
lit,
it
indicates
that
sufficient
power
is
coming
into
the
power
supply
through
the
power
cord.
During
typical
operation,
both
the
ac
and
dc
power
LEDs
are
lit.
For
any
other
combination
of
LEDs,
see
the
Problem
Determination
and
Service
Guide
on
the
IBM
System
x
Documentation
CD.
DC
power
LED:
Each
hot-swap
power
supply
has
a
dc
power
LED
and
an
ac
power
LED.
When
the
dc
power
LED
is
lit,
it
indicates
that
the
power
supply
is
supplying
adequate
DC
power
to
the
system.
During
typical
operation,
both
the
ac
and
dc
power
LEDs
are
lit.
For
any
other
combination
of
LEDs,
see
the
Problem
Determination
and
Service
Guide
on
the
IBM
System
