EMC DS-16B manual Error Message Formats, Front Panel, Feb 12

Error Messages

Error Message Formats

		There are two error message formats depending on whether you are
		gathering information from the front panel or via Telnet. The front
		panel shows an abbreviated message and via Telnet displays the
		entire error message.
		In all cases, the last error encountered is the first error displayed. Up
		to 32 messages are held in a buffer. If the 32 message limit is
		exceeded, the messages are overwritten in a first in, first out
		sequence.
		Error messages are stored in volatile RAM and are lost whenever power is
		removed from the switch. Access the error message log to view error
		messages before removing power.
Front Panel		The switch’s front panel displays error messages, as shown:
Message Formats
			Feb 12 08:48:29
			DIAG-REGERR_UNRST-1
		The first line includes the error’s date and time. The beginning of
		each second line on the front panel display starts with the module
		name (Diag), error name (REGERR_UNRST), and the severity level
	(1).
		The possible values are:
		•	1-critical
		•	2-error
		•	3-warning
		•	4-informational
		•	5-debug

If the same error occurs within the same module (for example, DIAG-REGERR_UNRST) but on different ports, the number of occurrences for that message is incremented in brackets (up to 999), and the error number is not incremented (that is, this error, though it may occur 999 times, occupies one message in the 32-message buffer.
