Power supply

Red

When the LED is off, it signals that the DC output voltage are within

 

activity

 

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.

 

 

 

 

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 2-21shows the common input ranges for reference only.

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 2-29—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.
