Troubleshooting The Dc-Input Power Subsystem; Troubleshooting A Dc Power Module - Cisco ASR 9001 Hardware Installation Manual

Troubleshooting the Installation
Procedure
Step 1 Make sure the power module is seated properly by ejecting and reseating the power module. Verify that:
• Latch on the ejector lever is locked securely.
• Power switch on the front panel is set to the ON position.
Step 2 Make sure the router is powered on and that all power cords are connected properly. Verify that:
• Power cables are securely attached to their power module terminal studs.
• Power cords at the power source end are securely plugged into their own AC power outlets.
• Source AC circuit breaker is switched on.
Step 3 Check the power supply status LED indicators:
• OK (green) Power LED—Indicates that the input AC power is OK.
If the OK LED is blinking, AC power input is operating normally, and the source AC input voltage of 100 to
240 VAC is within the nominal operating range.
• FAIL (amber) LED—Indicates the power supply failure, includes over voltage, over current, over
If the FAIL LED is blinking, it indicates alarm condition or power supply warning events, while the power
supply continues to operate; this includes high temperature, high power, or slow fan conditions. Make sure
that each power cord is connected to a dedicated AC power source. Verify that each AC power source is
operating in the nominal range of 100 to 240 VAC and is supplying a minimum service of 15 A, North America
(or 10 A, international).

Troubleshooting the DC-Input Power Subsystem

DC-input power supplies are monitored for internal temperature, voltage, and current load by the RP. If the
router detects an extreme condition, it generates an alarm and logs the appropriate warning messages on the
console.
The above figure shows the status indicators for the power module. The indicator definitions are provided
after the figure.
