Troubleshooting the Power Subsystem

•FAIL (amber) LED —Indicates the power supply failure, includes over voltage, over current, over temperature and fan failure conditions.

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.

Figure 4-1shows the status indicators for the power module. The indicator definitions are provided after the figure.

Troubleshooting a DC Power Module

Use this procedure to troubleshoot a DC power module if it is not operating properly.

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 cables are securely attached at the DC source end.

•Source DC circuit breaker is switched on.

Step 3 Check the power supply status LED indicators:

•OK (green) Power LED—Indicates that the input DC power is OK.

If the OK LED is blinking, DC power input is operating normally, and the source DC input voltage of –40 to –72 VDC is within the nominal operating range.

•FAIL (amber) LED —Indicates the power supply failure, includes over voltage, over current, over temperature and fan failure conditions.

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 cable is connected to a dedicated DC power source. Verify that each DC power source is operating in the nominal range of –40 to –72 VDC.
