CCTV Matrix Switch Power Supply
The Power Supply has only fuses that can be serviced. The integrity of these fuses can be visually
verified by observing the LEDs located next to each fuse holder on the front of the Power Supply. If the
LED associated with a fuse is not illuminated then the fuse needs replacing or the power supply is
defective. If replacing the fuse does not correct the problem or the fuse continually blows then the power
supply should be replaced. The Power Supply is of single piece construction and slides in to the Chassis
(to the far right) like a circuit card, however it is secured from the back of the chassis by four (4) screws
located around the AC Input receptacle.
