Installing a Redundant (second) Power Supply
To install a redundant power supply in a Matrix 200, disconnect the power
source, remove the Matrix from its rack mount, and place it on a clean
workspace. Refer to page 2-2 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 to the two vacant connectors
on the main controller board - next to the connectors from the primary power
supply.
4. Check the mounting and connections by comparing them with those for the
primary power supply.
5. Put the Matrix 200 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. If using an
RS-232/RS-422 interface, the Matrix Status Bytes will indicate this condition.
Before Installing I/O Modules
Before adding an I/O Module to an existing Matrix 200, you must know the
revision status of the Matrix. Page A-1 has a list of option kits and their part
numbers. It also explains what upgrades may be required before adding
modules.
_______ If the serial number has an “A” after it, the Matrix is ready for an Audio Module.
If the unit does not meet these requirements, go to the appropriate procedure to
bring it up to date and then do the Audio Installation.
Like the primary
power supply, the
redundant supply
has a 2-amp, fast-
blo fuse at the AC
input of each
board.
