If no faults occur, POST continues to execute. Upon completion of POST, the
C300 determines whether to transition to boot mode or application mode. If a
valid application image is present in the C300, then it is started in application
mode, unless the controller has been commanded to shutdown, or is
rebooted into the FAIL state.
The Status LED indicates the state of the controller's associated hardware.

The controller indicates '-bp-' on its display while it waits for a response from
the BootP Server service. The BootP Server supplies the C300 its IP
Address assignment and SNTP Server IP addresses. If no response is
received from the BootP Server in 2 minutes, the C300 will timeout.
Once the C300 receives a response from the BootP Server, '-TS-' is indicated
on the display while it waits for a response from the configured time source.
If the configured time source is not available, the controller will attempt to
connect with an alternate time source. See

Action: Verify the correct Device Index is shown on the display (#nnn) and
that there are no address errors.
Address errors - The C300 determines if any other module in the FTE
network is using the same Device Index. If another module is discovered
with the same Device Index, the C300 will not join the FTE network but
instead will enter the "no address" state and wait for a new Device Index to
be set.
If another node is discovered with the same IP Address, the controller will not
join the FTE network but instead will enter the "dup address" state and wait
for a new Device Index to be set.
Action: If the Device Index is invalid, or any address error is displayed, see
Res et Device Index and IP address of a controller
reassign the Device Index and IP addresses.
Once a valid IP Address is assigned, a redundant C300 negotiates its
redundancy role (primary/secondary) with its partner module. See Stage 10.

The C300 alternately displays its Device Index, redundancy role and
execution state on the controller's faceplate display.
Redundancy role - Question marks '????' may appear on the display to
indicate that the C300's redundancy role has not been determined. For non-
redundant controllers, the redundancy role is shown as 'nrdn.'
Execution state - If no EE databases have been retained in a primary or non-
