Troubleshooting Alarm Conditions

ICIM Alarm Conditions
If the red ALARM indicator is illuminated or is blinking, check the ICIM to
determine the cause of the alarm. Blinking = minor alarm, steady illumination =
major alarm.

Alarm Condition
Indicates that the FPGA
can be read from and
written to
Gets set when it is not
possible to read and
write the to EEPROM
in an installed OSM
(Transmitter sub-
module).
Status of +24V and –5V
power inputs.
Alarms when the 100
MHz clock does not
lock on to the 1 MHz
reference.
Alarm when 125 MHz
clock will not lock on
100 MHz clock
Transmitter sub-
module 1 is missing.
Laser 1 is near end of
life.
Laser 1 temperature is
out of spec.
Transmitter sub-
module 2 is missing.
Laser 2 is near end of
life.
Laser 2 temperature is
out of spec.
Maintenance and Troubleshooting
Indication Possible Cause
Fault Hardware failure.
Fault Ensure transmitter sub-module
is fully seated. Remove and
reinstall sub-module.
Fault Check power supplies. Make
sure the power supply module
is fully seated in chassis.
Fault Ensure processor Clk_Src has
not been accidentally set to
Slave. If in Slave mode make
sure there is a valid 1 MHz
reference present.
Fault Hardware failure.
Fault Ensure transmitter sub-module
1 is installed and fully seated.
Fault Time to replace transmitter
sub-module 1.
Fault Ensure transmitter sub-module
1 is within temperature specs
and laser has had a chance to
stabilize. Check chassis fans.
Fault Ensure transmitter sub-module
2 is installed and fully seated.
Fault Time to replace transmitter
sub-module 2.
Fault Ensure transmitter sub-module
2 is within temperature specs
and laser has had a chance to
stabilize. Check chassis fans.
