+24 VDC Power System Input for Cisco ASR 1002 Router

The +24 VDC power supply operates within specification between +21 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 the following table 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.
Two power supplies are used for redundant operation. System total power consumption shall never exceed
Note
rating of one power supply to maintain redundancy.

Description
LED illuminates green to signal
that voltage is > or = to 20VDC
at turn-on and down to
19.0VDC (+/- 0.5 V tolerance).
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.
The LED illuminates s green
when all fans are operational.
The LED illuminates red when
a fan failure is detected.
