4.1.1 Locating the Eclipse HX-Omega, Eclipse HX-Median and

Eclipse HX-Delta

The Eclipse HX-Omega and Eclipse HX-Median matrix frames each require six vertical

rack units (6RU) (10.5 inches or 267 mm) in a standard Electronics Industry Association 19-

inch wide (48.26 cm) rack. The Eclipse HX-Delta matrix frame requires three vertical rack

units (3RU) (5.25 inches or 134 mm) in the same 19-inch rack.

Cooling the Omega / Median matrix frame

Each matrix has two power supplies (one for redundancy). 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 LED on the front of the alarm module illuminates red to indicate that the

secondary fan is on. The red fan-fail alarm LED illuminates when either fan stops rotating

correctly. These alarm LEDs allow the system operator to identify and correct the alarm

conditions.

For more information, see the:

• Eclipse HX-Omega User Guide.

• Eclipse HX-Median User Guide

Environmental information:

• The air flow through a 6RU matrix frame from the bottom to the top must be

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 matrix frame to prevent over-heating.

• If the matrix is mounted in a portable case this air flow must not be impeded.

Cooling the Delta matrix frame

Each matrix has two external power supplies (one for redundancy). A modular removable

fan/alarm module at the front of the unit has two fans that deliver forced air cooling. Both

fans run continuously, but as the temperature increases, their speed increases to boost the

air flow in the matrix.

The fan fail alarm LEDs illuminate if the corresponding fan stops rotating correctly. These

alarm LEDs allow the system operator to identify and correct the alarm conditions.

For more information, see the

• Eclipse HX-Delta User Guide

Environmental information:

• The air flow through an Eclipse HX-Delta, left to right, must not be impeded. The

airflow in a standard 19-inch (48.26cm) rack should be sufficient. If the matrix is

mounted in a portable case, ensure that the air flow is not impeded.
