Table 2 describes the DC power supply LEDs on the Cisco ASR 1002-F Router.
Table 2 Cisco ASR 1002-F Router DC Power Supply LEDs
To connect the DC power supply to a Cisco ASR 1002-F Router, follow these steps:
Step 1 At the rear of the router, check that the power switch is in the Standby position on the power supply.
Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site.
Typically, green or green/yellow is used for ground. Make certain the lead color coding you choose for the DC-input
power supply matches the lead color coding used at the DC power source.
Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Statement 1046
LED Label LED Color Description
INPUT OK Power supply activity Green Signals that the DC power supply input voltage is greater
than –43.5VDC at turn-on and remains green down to
–39VDC.
Amber The power supply turns off due to low input voltage
(falls below –39VDC) and indicates that there is still a
voltage present (voltage on the terminal block). The LED
remains amber and is active to around 20V +/- 5V. The
LED is not illuminated if the input is below 15V.
FAN OK Power supply fan activity Green All fans are operational.
Red A fan failure is detected.
OUTPUT FAIL Power supply activity Red Output voltages below the minimum or above the
maximum limits 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.
Off DC output voltages are within the normal operating
range.
