Power Supplies for the Cisco ASR 1004 Router
DC Power System Input for Cisco ASR 1004
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 2-18
shows
the common input ranges for
reference
only.
AC/DC Power System Output for Cisco ASR 1004
The power supply output tolerance is defined in
Table 2-19
under all combinations of line variation.
Total system consumption per power supply should not exceed 735 W.
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.
