Cisco ASR 1000 Series Router Power Supplies
DC Power System Input for Cisco ASR 1004
The DC power supply operates within specification from –40.5VDC to –72VDC continuously once the
the power supply DC input turn on threshold of –43.5V has been reached. Table 2-20 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 2-16 under all combinations of line variation.
Total system consumption per power supply should not exceed 735 W.
Power Supplies for Cisco ASR 1002 Router
The Cisco ASR 1002 Router supports an AC or DC power supply:
• Cisco ASR 1002 Router AC Power Supply, page 2-27—The AC power supply operates between
85VAC and 264VAC. AC power input is an IEC 320-type power inlet, 15A service connector. The
AC input side contains a front panel with provisions for mounting screw, two built-in handles to
extract the power supply, three status LEDs, and fans for power supply and system cooling.
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 DC 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.
