PRELIMINARY
Reoving and Intalling the Controller Card and
Replacing the Firware
Reoving the priar or redundant controller card
N
The controller cards are hot-swappable. If this BME has redundant controller
cards, either controller card can be removed without powering down the
switcher. If the BME does not have controller card redundancy, removing the
controller card shuts down the matrix.
Remove the primary or optional redundant controller card as follows:
1. Open and remove the front door.
2. Turn the left and right knurled knobs on the fan assembly door ¼-turn
counterclockwise. Raise the door and rest it on the roof of the power
distribution enclosure.
C
Do not touch the electronic components or the connectors on the power
distribution plane or on the circuit cards without being electrically
grounded. Handle circuit cards by their edges only. ESD can damage
ICs, even if you cannot feel, see, or hear it.
3. Grasp the ejector lever on the top of the card to be removed (figure 6-11).
Pivot the ejector lever out and away from the center of the card to lever the
card out of the power distribution plane.
