LED Light Sequences
When a Switch Card is inserted into the Rack, the card displays a sequence of
LED lights. The proper startup sequence includes a set of fast red blinks,
followed by 3 green blinks, 4 yellow blinks, followed by 3 sets of 8 yellow
blinks. Once the Switch Card has completely restarted, the flashes or blinks
indicate the status of a different item.
