Matrix 12800 Switchers • Upgrades and Maintenance
CAMBOARD Electronics
Slide the board out of the cardcage.
Place the removed board on an anti-static surface or in an anti-static container.
If a replacement board is not being installed immediately, close the fan
assembly door and turn the left and right knurled knobs ¼-turn clockwise.
Ensure that you close and secure the fan assembly door when you have
finished this maintenance procedure. The Matrix 12800 may overheat
otherwise.
If a replacement board is not being installed immediately, close the front door.
The controller boards are hot-swappable. You do not need to power down the
switcher to install a controller board.
If necessary, open and remove the front door.
If necessary, 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.
Do not touch the electronic components or the connectors on the power
distribution plane or on the circuit boards without being electrically
grounded. Handle boards by their edges only. ESD can damage ICs, even
if you cannot feel, see, or hear it.
Orient the board to be installed so that the connector is on top (figure 6-11).
Pivot the ejector handle out and away from the center of the board.
Identify the correct location for the board. Align the top edge of the board
with the top guide. Gently slide the board into the cardcage ensuring that the
bottom edge slides into the bottom guide. Continue sliding the board into the
guides until the ejector handle contacts the guide frame.
Gently pivot the ejector lever in and down to seat the board in the power
distribution plane.
If the board installed is a replacement, set the DIP switches on the rear edge of
the board to the same setting as the board that was removed from this
location.
Close the fan assembly door and turn the left and right knurled knobs ¼-turn
clockwise.
Ensure that you close and secure the fan assembly door when you have
finished this maintenance procedure. The Matrix 12800 may overheat
otherwise.
Close the front door.
