Installing the power supply module

4.	If a replacement power supply is not being installed immediately, close the
	fan assembly door and turn the left and right knurled knobs ¼-turn clockwise.

CEnsure that you close and secure the fan assembly door when you have finished this maintenance procedure. The Matrix 12800 may overheat otherwise.

5.	If a replacement power supply is not being installed immediately, close the
	front door.

NThe power supply modules are hot-swappable. You do not need to power down the switcher to install a power supply.

Install a power supply module as follows:

1.	If necessary, open the front door.
2.	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.
3.	Orient the power supply module to be installed with the LEDs to the right
	and near the bottom (figure 6-5).
4.	Identify the correct position to install the power supply module. Align the
	flanges on the power supply module with the top and bottom power supply
	guides. Gently slide the power supply module into the power distribution
	enclosure until the module meets resistance.
5.	Push down on the thumb detent, and firmly push the power supply module
	the rest of the way into the power distribution enclosure until the power

supply module is properly seated on the power distribution plane. If the switcher is powered up, observe that the two LEDs light. Release the thumb detent.

CEnsure that you close the fan assembly door when you have finished this maintenance procedure. The Matrix 12800 may overheat otherwise.

6.	Lower the fan assembly door to vertical and turn the left and right knurled
	knobs ¼-turn clockwise.
7.	Close the front door.

NIf you are upgrading the matrix switcher from a configuration with two power supplies to a configuration with four power supplies (adding redundancy), you also need to plug in the redundant IEC power cord on the rear panel.

8. If power supplies were installed to add redundancy to the switcher, plug a standard IEC power cord between the rear panel Redundant AC Power Input connector and either an uninterruptible 100 to 240VAC, 50 Hz or 60 Hz power source or a power source that is completely independent from the primary power source.
