Apparent module failure
If a module failure occurs, check for possible backplane connection problems.
Make sure that the module is correctly seated in the backplane connector and that
the retaining screws are securely tightened.
If a module fails during module initialization and the replacement module is the
same module type, in rare cases the new module may not initialize.
To work around this issue, follow the steps in either work around 1 or 2.
Module failure work around 1
1 Remove the faulty module.
2
Insert a module type that is different from the module type removed in
Step 1and wait for this replacement module to initialize.
The Master LED on a
module in slot 1 or slot 2 is
amber. The module has detected a
system clock generation
failure on its own circuitry. Replace the module; make sure that it is in the
correct slot.
Note: This LED has significance only for the
module in slot 1 or slot 2 that provides the
clock function for the switch.
The Fault LED is blinking
amber. A chassis failure has been
detected. From the console management station, use
the
show log
command to check the system
log for information about hardware failures.
Check the fan tray in the Passport 8000
Series chassis to make sure both fans are
running.
Check the switch power supplies; one may
have stopped functioning.
The module may have failed to read the MAC
address from the chassis backplane. If this is
the case, arrange to replace the chassis.
The Fault LED is steady
amber. The module failed its
power-on self-test. A
diagnostic or hardware failure
has been detected. Replace the module.
No LEDs are lit. A hardware failure has been
detected. Turn the switch power off and then turn it on
again.
