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.
Fan-On Indicator
Two fans deliver forced air cooling to the matrix’s power supplies. The
primary fan runs continuously. If a temperature exceeding a threshold
is detected in a power supply and extra cooling is required, a second
fan switches on to increase the air flow. The “fan-on” alarm light
illuminates red to indicate that the second fan is on.
POWER SUPPLY LIGHTS
The green power-supply lights illuminate to indicate that the power
supplies are receiving +12 V, –12 V, +5 V, and 3.3 V power.
