Optional module port LED
If each Layer 2 of the 1PRI, 2PRI, or 2BRI card is judged to be connected, an
LED on the option module port turns on; as many LEDs on the option module port
as the number of the connected links turn on. The dislocation of a cable or a card
disconnects the corresponding link, which in turn causes an LED to turn off.
Note that resetting a card disconnects the corresponding Layer 2 connection but
not an LED. An LED gets turned off afterwards when the card is rebooted and
then turns back on again.
