To understand what CM_ALARM error codes mean, you need to first identify the structure
of the CM Alarm codes. A CM_ALARM code has the following structure:
Error type:
Major (1)
Minor (0)
According to the table above, the LSB (bit 0) identifies the Error Type (major alarm, if
the bit is set and minor alarm if the bit is unset). The rest of the bits (1 - 31) identify the
actual error code.
Take an example of the following error code, which was logged on a T1600:
Apr 12 08:04:10 send: red alarm set, device FPC 1, reason FPC 1 Major Errors
- Error code: 559
First, you have to convert 559 to binary; that is 1000101111. The LSB in this case is 1, which
means that this is a major alarm. After removing the LSB, you are left with 100010111,
which is equal to 279 in decimal. This is the actual error code, its meaning can be found
from the following list:
