Power Supplies for the Cisco ASR 1002 Router
–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.
Table 2-23
shows
the common input ranges for
reference
only. The –48 VDC power input connector is a Euro-style
terminal block that accepts three wires, one positive, one negative, and one grounding wire.
–48 VDC Power System Output for Cisco ASR 1002 Router
The –48 VDC power supply output tolerance is defined in
Table 2-24
under all combinations of –48
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.
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.
OUTPUT FAIL
Power supply
activity
Red
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.
