Neither R(un) nor F(ault) LEDs
are ON
The SM810/SM811/SM812 board is in the
process of being restarted or configured. Allow
time for this to finalize.
If the condition persists, and no other unit LED on
the CEX-Bus is lit:
• Check the Log File
• Check the CEX-Bus fuse inside the CPU unit.
• Initiate a reset signal (INIT) from the CPU
unit.
• Replace the SM810/SM811/SM812 unit.
F(ault) LED is ON Unit error. Replace the SM810/SM811/SM812
unit.
PRIM LED is flashing Unit error. Replace the SM810/SM811/SM812
unit.
PRIM LED is OFF in single
configuration.
Unit error. Replace the SM810/SM811/SM812
unit.
SYNC LED is flashing Upgrade in progress. When the LED is blinking
with a symmetric pattern, allow time for this to
finalize. If the LED is blinking with a 3 blinks and a
pause sequence, the SM811/SM812 is ready for
acknowledgment of SIL3 hot insert, see SM811
and TP868 on page 300 and see SM812 and
TP868 on page 306. If the condition persists for a
longer time, replace the SM811/SM812 unit.

The PM8xx is transmitting and the
Tx1/Tx2 LEDs are flashing, but
the connected device is not
receiving data.
OR
The connected device is
transmitting, but the Rx1/Rx2
LEDs are not flashing.
• Check that the communication
interface cable is connected.
• Check the hand-shake signals.
The Tx/Rx signals are flashing
concurrently with
transmission, but the messages
are not being received correctly
by the connected device.
• Check that the baud rate, parity, and
number of data and stop bits are as
specified for the connected device.
• Check that the handshake procedures
are as specified at both ends.
• Check that the driver routines are
adequate, both in the controller and
the connected device.
• Disconnect power to the controller,
wait a moment and then power-up
again.
• Halt the program and initiate a reset
signal (INIT) from the PM8xx
processor unit.
CI853 supports hot swap.

The CI854/CI854A/CI854B board is in the process
of being restarted or configured. Allow time for this
to finalize.
If the condition persists, and all other units on the
CEX-bus have non-illuminated LEDs:
• Check that a valid HW configuration including
the CI854 is downloaded to the controller.
• Check the CEX-bus fuse inside the PM8xx
processor unit.
• Initiate a reset signal (INIT) from the PM8xx
processor unit.
• Replace the CI854/CI854A/CI854B unit.
F(ault) LED is ON Check that the CI854 board is in the process of
being restarted. Allow time for this to finalize.
Check that there is no configuration fault reported
from CI854/CI854A/CI854B in CBM.
If the status remains initiate a reset signal (INIT)
from the PM8xx processor unit. If the status still
remains after the reset replace the
CI854/CI854A/CI854B unit.
RxA LED is OFF No communication on Line A.
• Check that slaves are configured and
connected to this line.
• If redundant slaves are used check that the
redundancy is working properly. The backup
slave has to answer to the life list requests
sent by the master.
• Check all cables and connectors for damage
and loose or poor connections.
