Module’s network address is set to 00, an
invalid ControlNet address, or 99, an invalid
ControlNet address if you are using redundant
control. See footnote at end of table.
1. Optional – Turn chassis power supply
off.
2. Remove the module from the chassis.
3. Set the network address switches to a
unique address (01-99, or 01-98 if
redundant control)
4. Install the module in the chassis.
5. If off, turn chassis power supply on.
BPA# ERR Module detected a different slot address from
that latched in at power-up. Excessive noise on
the backplane causes this error.
Replace the chassis or module.
BPRX ERR Too many CRC errors being generated by the
multicast backplane receiver, so the backplane
multicast receivers have been shut off.
Replace the module.
BPIC
ERR
Hardware fault within the module. Replace the module.
CNIC
ERR
DUPL NODE For a redundant system this may be a temporary
condition during chassis switchover. Otherwise,
the module’s network address is the same as
another module’s on the link.
For redundant systems only. wait 10 seconds; if
the condition persists, do the following steps:
1. Turn chassis power supply off.
(Optional)
2. Remove the module from the chassis.
3. Set the network address switches to a
unique address (01-99).
4. Install the module in the chassis.
5. If off, turn chassis power supply on.
RACK ERR Cannot read backplane EEPROM, or rack/slot
address incorrect
Replace the chassis.
STOP CNB commanded to stop functioning by the
redundancy module. This occurs when a
non-redundancy compliant CNB is placed into a
redundant secondary chassis.
Remove non-redundancy compliant CNB from
redundant secondary chassis and replace with
redundancy compliant CNB.
WAIT RM CNB waiting for the redundancy module to
complete power-up.
None required.
