CTI 2572-A Installation and Operation Guide V1.3 63
8.3. Module Startup Problems
Before the module can communicate with other TCP/IP hosts, it must complete startup operations. If
the MS LED Steady Green and the NS LED is Steady Green, the module has successfully completed
startup. Otherwise, a problem has been encountered during module startup. See the table below to
determine that cause of the problem.
SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
No LEDs are illuminated. No Power to Module. Ensure that power is supplied to the rack
and that the module is securely inserted.
Defective Module. Cycle the power. If the problem persists,
contact CTI.
The module does not
execute the Lamp Check
Sequence. The bootloader software did not
start. It may be corrupted. Reset the module. If the problem persists,
contact CTI.
MS LED is Steady Red. NS
LED is flashing Red. The module application firmware is
corrupted. The module was unable
to download new firmware because
the information needed to download
the firmware cannot be obtained
from EEPROM. Start the module using DHCP after
configuring DCHP to provide the boot file
and TFTP server path. See APPENDIX E.
USING DHCP for details on configuring a
DHCP server. Once this is done, the
module will automatically download new
application firmware.
MS LED is Steady Red. NS
LED is Steady Red.
The module application software is
missing or corrupted. The module
was unable to download new
software because of one of the
following conditions:
1) the TFTP server could not be
contacted,
2) A valid software file could not be
found,
3) An unrecoverable error was
during file download.
Reset the module to retry the operation.
Observe the transient states of the NS LED.
If NS LED does not become solid green at
some time (indicating that a file download is
in progress), then server or file cannot be
located. Ensure the following:
- Module is connected to the network.
-
The TFTP server is present and can be
accessed via the network (try pinging
the server IP address).
-
The software files are installed in the
correct directory on the TFTP server.
Else, ensure that all required files are in the
correct directory. If files are missing, replace
all of the files. Also, check the network and
server loading. It is possible that heavy
loading can cause a timeout error while
downloading files.
MS is Steady Red,
NS is Off The module application software is
corrupted. A new program was
successfully downloaded but could
not be written to flash. Reset the module to retry the operation. If
this problem persists, contact CTI.
MS is Flashing Red
NS is Steady Red Unable to read the Ethernet MAC ID
from EEPROM. Reset the module to retry the operation.
If the problem persists, contact CTI.
MS is Flashing Red
NS is Flashing Red Unable to obtain the IP parameters
from EEPROM. Use CTIDiag to manually enter the IP
parameters via the serial port and reset the
module.
OR
configure a DHCP server with the required
IP information (see APPENDIX E. USING
