Table 54: Cisco ASR 1002 Router – 48 VDC Power Supply LEDs
Description Color LED LED Label
LED illuminates green to signal
that the DC power supply input
voltage is greater than 43.5VDC
at turn-on and remains green
down to 39VDC. Green A bi-color LED indicates
presence of input voltage INPUT OK
The LED illuminates amber if
the power supply turns off due
to low input voltage (falls below
39VDC) and indicates that there
is still a hazard present (voltage
on the terminal block). The
LED remains amber and is
active to around 20 V +/-5 V.
The LED is not illuminated if
the input is below 15 V. Amber
The LED illuminates s green
when all fans are operational. Green A bi-color LED indicates power
supply fan status FAN OK
The LED illuminates red when
a fan failure is detected. Red
When the LED is off, it signals
that the DC output voltage are
within the normal operating
range. Output voltage between
the minimum and maximum
limits will not create an output
fail alarm, and output voltages
below the minimum or above
the maximum will create an
Output Fail alarm.
Led illuminates red to indicate
that the DC output is out of the
specified range.
When you turn the power
supply on, the red LED
illuminates for two to three
seconds to test LED operation
before going off.
Red Power supply activity OUTPUT FAIL
The output voltage alarm is declared when the output voltage is below the low end of the minimum or above
the high end of the maximum limits. When the output voltage is above the high end of the minimum or below
the low end of the maximum limits, the red state will not be activated.
