1.
Perform
this
procedure
by
selecting
Manual

2.
Record
all
of
the
SRC
data

3.
Power
off
the
system
from
the
control
panel.
Check
the
cables
and
connections
between
the
System
Unit,
the
load
source
IOP
and
the
load-source
device.
Reseat
cables
where
possible.
Power
on
the
system.
Does
the
same
SRC
occur?
v
Yes
:
Continue
with
the
next
step.
v
No
:
Follow
the
service
actions
for
the
new
SRC.

is
the
first
word
in
the
control
panel
function

If
word
7
is
non-zero,
it
is
the
DSA
of
the
IOP
being
used
when
the
error
occurred
(IIIIIIII).
If
word
8
is
non-zero,
it
is
the
device
unit
address
of
the
load
source
device
being
used
when
the
error
occurred
(DDDDDDDD).
If
word
9
is
non-zero,
it
is
the
ID
