Connecting the –48 VDC Input Power to the Cisco ASR 1002-X Router
5 Fan
The following table describes the LEDs on the Cisco ASR 1002-X Router –48 VDC power supply.

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. Ensure the lead color coding
you choose for the –48 VDC input power supply matches the LED color coding used at the –48 VDC power
source.
Danger When you install the unit, the ground connection must always be made first and disconnected last. Statement

Color Description
Green LED turns green to signal that the –48 VDC power supply input voltage is greater
than 43.5VDC at start and remains green down to 39VDC.
Amber The LED turns amber if the power supply turns off due to low input voltage (falls
below 39VDC) and indicates that there is still a hazard present (voltage on the
terminal block). The LED remains amber and is active till around 20 V +/-5 V. The
LED is not illuminated if the input is below 15 V.
Green The LED turns s green when all the fans are operational.
Red The LED turns red when a fan failure is detected.
Red When the LED is off, it signals that the –48 VDC output voltage is 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.
The Led turns red to indicate that the –48 VDC output is out of the specified range.
When you turn the power supply on, the LED turns red for 2 to 3 seconds to test
the LED operation before going off.
At the rear of the router, check that the power supply Standby switch is in the Standby (see
Cisco ASR 1002-X Router –48 VDC Power Supply Terminal Block Cable Connections, on page 35
position.
Ensure that the negative and positive leads are disconnected from the site power source.
Using a wire stripper, strip approximately 0.55 inch (1.39 cm) from the negative, positive, and ground
lead.
