Chapter 16: Troubleshooting T640 Router Hardware Components Troubleshooting the T640 Power System Problem The following alarms, LEDs, and other conditions indicate a problem with the power system: · If all power supplies have failed, the system temperature might have exceeded the threshold, causing the system to shut down. The following indicate a problem on a two-input 160-A DC power supply: · · · The DC OK and CB OK LEDs are off. If the yellow CB TRIP LED lights but the power supply is not going through a startup test, the power supply detects a fault (the power supply fails, does not have sufficient airflow, or is not properly inserted). The yellow OVER TEMP LED lights when the power supply is not receiving enough airflow to maintain proper temperature. · · The following indicate a problem on a three-input 240-A DC power supply or four-input 240-A DC power supply: · · The blue DC OK LED is off. If the blue DC OK LED blinks but is not going through a startup test, the power supply detects a fault (the power supply fails, does not have sufficient airflow, or is not properly inserted). The yellow OVER TEMP LED lights when the power supply is not receiving enough airflow to maintain proper temperature. The INPUT PRESENT LED is off, indicating that the input is not receiving source DC power. If the INPUT PRESENT LED is lit but the CB ON LED is off, it indicates that the circuit breaker is off. · · · · The following indicate a problem on a three-phase delta or wye AC power supply: · · · The green AC OK LED is off when the power supply is not receiving source AC power. If the blue DC OK LED blinks but is not going through a startup test, the power supply detects a fault (the power supply fails, does not have sufficient airflow, or is not properly inserted). The yellow OVER TEMP LED lights when the power supply is not receiving enough airflow to maintain proper temperature. · Copyright © 2010, Juniper Networks, Inc. 171 T640 Core Router Hardware Guide During normal operation: · · The blue DC OK LEDs light to indicate that the power supplies are functioning normally. The green CB ON and the blue DC OK LEDs on each two-input 160-A DC power supply faceplate are on, indicating that the power source is good and the power supplies are functional. For a three-input 240-A DC power supply or four-input 240-A DC power supply: · · The green INPUT PRESENT and the blue DC OK LEDs are on, the power source is good and the power supplies are functional. Each INPUT PRESENT LED is lit, indicating that the input is receiving source DC power. The CB ON LED is lit, indicating that the circuit breaker is on. · · · For a three-phase delta or wye AC power supply: · The green AC OK LED is lit, indicating that the power supply is receiving source AC power. The blue DC OK LED is lit, indicating that the power supply is functioning normally. · Solution To troubleshoot the T640 power system: 1. If the OVER TEMP LED on one of the power supplies lights, check the fans and air filters in the chassis to be sure they are functioning and providing sufficient airflow. 2. [. . . ] Remove the cables that connect to all external devices. Remove all Field Replaceable Units (FRUs) from the router. Remove the router from the rack: · If you are using a mechanical lift, place the lift platform under the router, unscrew and remove the mounting screws from the rack, and move the router to the shipping crate. If you are not using a mechanical lift and the router weight is fully supported by a shelf or another router, unscrew and remove the mounting screws from the rack. [. . . ]
