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. The
amber
(XP) or
red
(Power-One) 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:
The PSU1 fail light only works if the first power supply is plugged into the matrix’s midplane
from inside the matrix.
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 first power supply unit is operating correctly, the
red
PSU2 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
PSU2 light
switches on. The
amber
(XP) or
red
(Power-One) 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:
The PSU2 fail light only works if the first power supply is plugged into the matrix’s midplane
from inside the matrix.
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 alarm light
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.
5.7.5 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.
