tape backup device(compaq dlt 15/30) has yellow and green led's the top one is tape in use and it is usually yellow, the bottom one is unload tape and is usually green, when I go to change the tape in the morning the "tape in use" light is usually on, but lately the "unload tape light" is on in the morn, does anyone know what the proper light sequence is, or what exactly do the lights mean. prior to this and the way it should be is When the backup job is completely finished the light is always yellow until I press the unload tape button then it turns green. Any Idea's?
