Cisco ASR 1002 Router Power Supplies
This section describes how to connect the –48 VDC power supply in the Cisco ASR 1002 Router.
Note
The color coding of the –48 VDC input power supply leads depends on the color coding of the –48 VDC
power source at your site. Typically, green or green/yellow is used for ground. Make certain the lead
color coding you choose for the –48 VDC input power supply matches lead color coding used at the –48
VDC power source.
Warning
When you install the unit, the ground connection must always be made first and disconnected last.
Statement 1046

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.
Led illuminates red to indicate that the –48 VDC output is out of the
specified range.
When you turn the power supply on, the red LED illuminates for two
to three seconds to test LED operation before going off.
