Cisco ASR 1002-X Router Description
Table 10-5 shows the definitions of the Cisco ASR 1002-X Router +24 VDC power supply LEDs.
Table 10-5 Cisco ASR 1002-X Router +24 VDC Power Supply LEDs
+24 VDC Power System Input for the Cisco ASR 1002-X Router
The +24 VDC power supply operates within specification between +21 VDC and +36 VDC continuously
after the power supply DC input is turned on. The power supply measures the input voltage at the power
supply terminals and turns off the supply when the input voltage reaches 19.0 V +/- 0.5 V when this low
voltage threshold is reached, the power supply does not resume operation until the input voltage reaches
20.0 V +/- 0.5 V. When the turn-on threshold of 20 V is reached, then the +24 VDC power supply meets
all specification requirements down to the low voltage threshold of 19 V (+/- tolerance).
LED Label LED Color Description
OUTPUT FAIL Power supply activity Red When the LED is off, it signals that the +24 VDC output
voltage is within the normal operating range. Output
voltage between the minimum limit and maximum limit
will not create an output fail alarm, but output voltages
below the minimum limit or above the maximum limit
will create an Output Fail alarm.
When you turn the power supply on, LED turns red for
two to three seconds to test the LED operation before
going off.
INPUT OK A bicolor LED indicates
the presence of input
voltage
Green The LED turns green to signal that voltage is > or = to 20
VDC at turn-on and the voltage reduces to 19.0VDC (+/-
0.5 V tolerance).
Amber The LED turns to amber when the input voltage is active
and is reduced to 16.0 VDC and indicates that a voltage
on the terminal block is still present. The LED remains
amber and is active until around 10 V. The LED should be
OFF below 15.8 VDC.
FAN OK A bicolor LED indicates
the power supply fan
status
Green The LED turns to green when all fans are operational.
Red The LED turns to red when a fan failure is detected.
