Power on detected errors
This section describes core utilities board (CUB) LED errors from
highest to lowest priority detected at power on. The Attention LED on
the core utilities board (CUB) turns on, and the Attention light bar on
the front of the node flashes to indicate the presence of an error code
listed in Table 15. Additionally, only the highest priority error is
displayed. Once remedied, an error that is cleared may expose a lesser
priority error.
Errors are listed in sequence from the highest to lowest priority.
Errors from LED hex code 00 through hex code 67 shut the system down,
and errors from hex-code 68 through 73 leave the system up.
