Table 2 describes the DC power supply LEDs on the Cisco ASR 1002 Router.
Table2 Cisco ASR 1002 Router DC Power Supply LEDs
To connect the DC power supply to a Cisco ASR 1002 Router, follow these steps:
Step 1 At the rear of the router, check that the power switch is in the standby position.

LED Label LED Color Description

INPUT OK A bi-color LED indicates
presence of input voltage
Green Signals that the DC power supply input voltage is greater
than –43.5VDC at turn-on and remains green down to
–39VDC.
Amber The power supply turns off due to low 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 20V +/-5V. The
LED is not illuminated if the input is below 15V.
FAN OK A bi-color LED indicates
power supply fan status
Green All fans are operational.
Red A fan failure is detected.
OUTPUT FAIL Power supply activity Red It is off 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.
When you turn the power supply on, the red LED
illuminates for two to three seconds to test LED
operation before going off.
