A7006984 A7006984

Explanation
 System log entry only, no service action required

Response
 An HSL loop has switched to its alternate path. 
This is an informational SRC only.

Word 7 of the SRC contains the loop number in the
leftmost 4 digits.  The loop number is in hexadecimal
format. You must convert the hexadecimal loop number 
into decimal format to recognize the loop number.

This SRC can be caused by a tower on the HSL loop powering
off.

This SRC may also appear in a Serviceable Event View you are

using, with a B700 6982 or B700 6981 logged at approximately

the same time.
In that case the other SRC is reporting a failure and this
SRC
is reporting that the alternate RIO path is now being used. 
Service the other SRC if present.
