MAP 0340: MNTN Code 25
MNTN means that your CPSW2 enters in maintenance mode. Connect a local console to your CPSW2
and, according to the >>25 message displayed on the CPSW2, perform the action specified.
IPC Register
The IPC register test is done only on the active CPSW (not on the redundant one). In addition the
behaviour, in case of test failure, is not the same if the IPC is master or not and if there is or not the
manufacturing wrap plug.
The IPC is not master (Remote power controller has the control)
If one of the IPC register is found failing during the test the boot code does not stop but a record is
made into the error log to inform about the register in error and the bit of that register which has
been detected bad.
The IPC is master.
If only the LED register is failing the test there is only a record made into the error log.
If either the PWR enable register or the I2C data register is failing the test a record is made into
the error log and the boot code goes in maintenance mode (code = 25)
The following message are sent to the display according to the register in error.
With the PE agreement replace the CPSW2 card. Go to Chapter 5, “CE Leaving Procedure” on
page 5-1.
Symptom Explanation
MNTN is displayed on the CPSW2 alternating with a message giving information about the reason of
the error
