Cisco ASR 1002 Router Description
The Cisco ASR 1002 24 VDC power supply LEDs are defined in
Table 8-5

Cisco ASR 1002 24 VDC Power Supply LEDs
+24 VDC Power System Input for Cisco ASR 1002 Router
The +24 VDC power supply operates within specification b21 and +36 VDC continuously once
the power supply DC input is turned on. The power supply shall measure the input voltage at the
terminals of the power supply and turn off the supply when the input voltage reaches 19.0 volts +/- 0.5
volts. Once this low voltage threshold is reached, the power supply does not resume operation until the
input voltage has reached 20.0 volts +/- 0.5 volts. Once the turn-on threshold of 20 volts is reached, then
the +24 VDC power supply meets all specification requirements down to low voltage threshold of 19
volts (+/- tolerance).
+24 VDC Power System Output for Cisco ASR 1002 Router
The +24 VDC power supply output tolerance is defined in
Table 8-6
under all combinations of +24 VDC
input line variation. Total system power consumption should not exceed 470 watts or output rating of
each power supply.
Note
Two power supplies are used for redundant operation. System total power consumption shall never
exceed rating of one power supply to maintain redundancy.

Color
Description
OUTPUT FAIL
Power supply activity
Red
When the LED is off, it signals that the +24 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.
INPUT OK
A bi-color LED indicates
presence of input voltage
Green
LED illuminates green to signal that voltage is > or = to
20VDC at turn-on and down to 19.0VDC (+/- 0.5 V
tolerance).
Amber
The LED illuminates amber when the input voltage is
active down to 16.0VDC and indicates that there is still a
voltage present (voltage on the terminal block). The LED
remains amber and is active to around 10 V. The LED can
be OFF below 15.8VDC.
FAN OK
A bi-color LED indicates
power supply fan status
Green
The LED illuminates s green when all fans are
operational.
Red
The LED illuminates red when a fan failure is detected.
