Temp Alarm
The red “temp” alarm light switches on to indicate one or both of the
following:
• The active CPU card has detected a temperature in the matrix above
a threshold.
• 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.
