Configuration Modes - Motorola APEX1000 Installation And Operation Manual

CAUTION The response packet may also contain a gateway if the BOOTP server is on a different
network segment than the APEX1000 Ethernet interface.
Upon receipt of the BOOTP reply, the APEX1000 obtains the FOF filename
(apex1000.fof) and path. It then downloads it from the BOOTP server. The APEX1000
then parses the FOF and compares the listed source files in the FOF with those
maintained in the APEX1000 local copy of the previously used version.
•
If any listed source filename or path has changed, or if there is a force download flag
for any listed files (an F is shown at the end of the line listing the file), the listed file
is then downloaded to the APEX1000.
•
If a downloaded FOF and the APEX1000 local copy are the same and a force
download flag does not exist in that FOF, the APEX1000 does not download any
additional files. It continues booting using the values stored in non volatile memory.
•
An FOF and other downloaded files are transferred through Trivial File Transfer
Protocol (TFTP).
•
Initialization is complete when the APEX1000 finishes loading the executable
software and operating parameters, either from a new download or from memory.

Configuration Modes

The APEX1000 can be configured to use either a BOOTP or a no BOOTP request.
Typically, the APEX1000 is configured to perform a BOOTP request (this is the factory
default).
Note: When configured to not issue a BOOTP request, the APEX1000 must already
contain all files it needs in non-volatile memory. Motorola recommends that you only
configure the APEX1000 in this manner after it has been initially installed and loaded.
Configuring the APEX1000 to not issue a BOOTP request will eliminate the chance that
on a reboot, the APEX1000 will download an unwanted configuration file. This typically
occurs when the user added a Force flag to a line in the file of files and forgot to remove
the Force flag.
The APEX1000 will reboot approximately ten seconds faster.
CAUTION During the download process, undetected transmission errors can cause initialization
failure. Always retry the initialization at least once before searching for a specific fault.
