Controller card
The controller cards have a green LED and a red LED that are visible through holes
in the I/O cardcage door. In a BME with a redundant controller, the green LED on
the active controller flashes to indicate that it is primary. In a BME with only one
controller card, or if you pull one of the hot-swappable controller cards, both LEDs
flash to indicate that the card is the primary controller.
N
The controller cards are hot-swappable. If this BME has both primary and
redundant controller cards, either controller card can be removed without
powering down the switcher. If the BME does not have both primary and
redundant controller cards, removing the controller card shuts down the matrix.
Symptom

switcher has stopped.
The controller board
has failed.
1. Remove and reseat the controller card.
The status page
indicates that one or

card(s) has failed.
