ECLIPSE OMEGA MATRIX INSTRUCTION MANUAL
2-13
• One of two CPU cards has been removed from the matrix. (Note that this
feature only operates if there are two CPU cards installed in the matrix. If
there is only one CPU card, the Temp alarm light does not switch on if the
card is removed.)
Fan-Fail Alarm
The red fan-fail alarm light illuminates when either fan in the power-supply
module stops rotating correctly.
PSU1 Fail
When the first power supply unit is operating correctly, the red PSU1 light stays
off, while the four green power supply lights (+12V, +5V, +3.3V, -12V) stay on
continuously.
If a DC output or AC input to the first power supply drops too low, the red
PSU1 light switches on to warn you. (The amber light on the power supply unit
itself also switches on to indicate the same condition.) One of the green power
supply lights may then switch off to help indicate the source of the trouble.
Note that the PSU1 fail light only works if the first power supply is plugged into
the matrix’s midplane from inside the matrix.
Note: A temperature sensor inside the power supply senses if the power supply
overheats, and switches on the second matrix cooling fan. The red “Temp”
light switches on to indicate that the active CPU card, not a power supply,
has overheated.
PSU2 Fail
When the second power supply unit is operating correctly, the red PSU2 light is
off, while the four green power supply lights (+12V, +5V, +3.3V, -12V) are on
continuously.
When a DC output or AC input to the second power supply drops too low, the
red PSU2 light switches on to warn you. (The amber light on the power supply
unit itself also switches on to indicate the same condition.) One of the green
power supply lights may then switch off to help indicate the source of the
trouble.
Note that the PSU2 fail light only works if the second power supply is plugged
into the matrix’s midplane from inside the matrix.
Note: A temperature sensor inside the power supply senses if the power supply
overheats, and switches on the second matrix cooling fan. The red “Temp”
light switches on to indicate that the active CPU card, not a power supply,
has overheated.
