Diagnosing Power Supply Problems

The Eclipse HX-Median has two Euro Cassette power supply units. One power supply unit can power an entire matrix. The second unit provides a backup in case of an equipment failure.

Eclipse HX-Median matrices may be fitted with XP (part 740101Z) or Power-One (part 720379Z) power supply units, depending on the date of manufacture. Each cassette has two status lights located on the power supply unit in the upper left corner.

The green light stays on continuously to indicate that the unit is receiving appropriate power. The amber (XP unit) or red (Power-One) light goes on when a DC output or AC input falls too low.

The different types of power supply units must not be mixed in an Eclipse HX-Omega matrix; if one of the pair of power supplies is replaced it must be replaced with the same type of power supply unit. If this is not possible both power supplies must be replaced with power supply units of the same type.

Power-One/Bel Fusepower supplies are identified by the part number on the front of the unit; XP units do not have a part number on the front of the unit.

The front panel alarm lights, power supply lights, and reset button are shown in Figure 24.

An alarm source triggers the red main alarm light and also one of the additional six red alarm lights, allowing the system operator to identify or correct alarm conditions before they affect the operation of the matrix.

Each of the four green power supply lights stays on continuously to show that the power supplies are receiving sufficient AC current. When one of these lights switches off, the power supplies must be replaced or repaired.

Under normal operating conditions, the red front-panel alarm lights stay off, while the green power supply lights stay on continuously.

Notes: The XP type power supplies (part 740101Z) may need to be adjusted if E-QUE, E-FIB, IVC-32 or LMC-64 interface cards are installed. For more information, see the Eclipse HX Upgrade Guide.
  Power-One/Bel Fusepower supply units (part 720379Z) should not be adjusted.
