Do a "list config soft". It will tell you the date and time of the last translations saved on the backup media. If the date and/or time differ it will pull an alarm, the switch compares the two and if there is a difference it will alarm. You will probably have to do a "save trans" on the active spe, switch to the offline spe and do a "save trans" again. This should clear the alarm. After you are done do a "list config soft" and check the dates and times. They should match now. Hope this helps.
