Clear-Com HX System Frames - Manual (Page 64)

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.

Figure 21: Power supplies: Front panel lights and controls
Figure 20 illustrates the front panel alarm lights, power supply lights, and reset button. An
alarm source triggers the 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.
