lights allow the system operator to identify and correct the alarm
conditions. See the Eclipse Omega Matrix Instruction Manual (part
810290Z) for more details.
Caution: It is mandatory that the air flow through an Eclipse Omega
matrix from the bottom to the top is unimpeded. If other
equipment is mounted above and below the matrix that
impedes the air flow through the matrix, it will be necessary
to leave 1 RU of empty space above and below the Eclipse
Omega matrix as over-heating will occur if this is not done. If
the matrix is mounted in a portable case this air flow must not
be impeded.
Eclipse Median Matrix
The Eclipse Median matrix requires six vertical rack units (10.5 inches
or 267 mm) in a standard Electronics Industry Association 19-inch
wide (48.26 cm) rack. There are two power supplies in each matrix. A
modular removable alarm module fitted beneath the two power
supplies has two fans that deliver forced air cooling. The primary fan
runs continuously. If the temperature in the matrix exceeds a set
threshold and extra cooling is required, a secondary fan switches on to
increase the air flow in the matrix.
The “fan-on” alarm light on the front of the alarm module illuminates
red to indicate that the secondary fan is on. The red “fan-fail” alarm
light illuminates when either fan stops rotating correctly. These alarm
lights allow the system operator to identify and correct the alarm
conditions. See the Eclipse Median Matrix Instruction Manual (part
810347Z) for more details.

Eclipse Pico Matrix
The Eclipse Pico matrix requires one vertical rack unit (1.75 in. or
44.45 mm) in a standard Electronics Industry Association 19-inch
(48.26 cm) rack. A temperature-controlled fan cools the Eclipse Pico
and forces air through the unit horizontally. An alarm light on the front
panel of the Eclipse Pico alerts the system operator when the
temperature-controlled fan activates.
