EqualLogic PS6510 - replaced failed disk but alarm LED still showing on the front?

I had a failed disk on my PS6510X array, which got replaced after placing a ticket through Dell. In my Group Manager GUI I can see the new disk has been marked as a spare, and there are no outstanding alerts/alarms. This is what I expected. However on the front of the array itself I have an orange LED and the text still says that the disk is faulty. This is the same text that displayed before it was replaced. It's like it hasn't been reset. So the GUI says all is ok but the lights say otherwise. What gives? Is there some way to "reset" the LED/text without bouncing the SAN?
