MATRIX CHASSIS

The matrix chassis is a metal rectangular box which measures six rack
units high and 19-inches wide (26.9 cm x 48.3 cm). It has slots for 2
CPU cards, 9 port/expansion circuit cards, 8 interface circuit cards,
and 2 power supplies.
RJ-45 and fiber-optic connectors are located on removable plates on
the rear of the chassis. These connect the circuit cards to intercom
devices and media such as panels, interfaces, 4-wire audio
equipment, wireless equipment and fiber-optic cables.

CIRCUIT CARDS

The matrix holds three types of circuit cards: CPU cards, port cards,
and interface cards. The cards slide vertically into the front of the
matrix and connect to the matrix's backplane.

CPU Card

The CPU card is the master configuration card in the Eclipse Median
system. It provides the serial data and Ethernet connection to the
connected PC computer. The CPU card also coordinates the data flow
between the other cards in the system, allowing them to communicate
with each other. The computer memory chip which stores four
complete system configurations is located on the CPU card, so that a
selected configuration can be retrieved and activated directly from the
card.
Like the other cards in the system, the CPU card fits in the Eclipse
Median matrix. The card fits vertically in a six rack unit (6 RU) space
and connects to the matrix's backplane.
One CPU card is required for each Eclipse Median system. Two cards
can be installed to provide redundancy in the case of outages or repair
needs.
