D
VOX Lights
When lit a VOX light indicates that the audio level on a connected device,
such as an intercom panel or interface, has exceeded a preset threshold. The
threshold audio level is set through the EHX application.
Each of the port card’s 16 green VOX lights corresponds to one of 16 rear-
panel connectors or “ports” to which audio devices (intercom panels or
interfaces) can be connected.
E
Frame Data Light
The green frame data light flashes (1: 1 0.5Hz) to indicate successful
communication between the port card and the CPU card.
Status Light
The red status light illuminates to indicate a failure in communication
between the port card and the CPU card.

5.7 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 power 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.
