Installing a Redundant Power Supply
To install a redundant power supply in a Matrix 100, disconnect the power
source, remove the Matrix from its rack mount, and place it on a clean
workspace. Refer to page 4-2 to remove the cover. With the cabinet open, do
the following:
1. Mount the new power supply on the four bolts projecting up from the bottom of
the cabinet and secure it with four nuts. This position is parallel to that of the
primary power supply. (See dotted lines in picture.)
2. Connect the two twisted power cables from the second IEC connector to the
inputs on the new power supply boards. See dotted lines in picture below.
3. Connect the two black power output connectors (6-pin) to the two vacant
power connectors on the main controller board, next to the connectors from
the primary supply.
4. Check the mounting and connections by comparing them with those for the
primary supply.
_________ Be sure that the striped green Ground wires are connected as shown to the left.

5. Put the Matrix 100 back together and connect both AC power sources.
6. To check the operation of the redundant supply, turn the AC switch Off. The
Matrix should function normally using the redundant power supply and the
Power LED should blink. If using an RS-232 interface, the Matrix Status
Bytes will indicate this change in condition.

Like the Primary power supply, the Redundant supply has a 4-amp, fast-blo fuse
at the AC input of each board (inside the matrix).
