–48 VDC Power System Input for Cisco ASR 1002 Router
The –48 VDC power supply operates within specification from –40.5VDC to –72VDC continuously once the
power supply –48 VDC input turn on threshold of –43.5 V has been reached. The following table shows the

Description
LED illuminates green to signal
that the –48 VDC power supply
input voltage is greater
than–43.5VDC at turn-on and
remains green down to
–39VDC.
The LED illuminates amber
when the input voltage (falls
below –39VDC) and indicates
that there is still a voltage
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.
The LED illuminates s green
when all fans are operational.
The LED illuminates red when
a fan failure is detected.
When the LED is off, it signals
that the –48 VDC 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.
When you turn the power
supply on, the red LED
illuminates for two to three
seconds to test LED operation
before going off.
