• Verify that the source circuit breaker has the proper current rating. Each power supply
must be connected to a separate source circuit breaker.
• Verify that the AC power cord or DC power cables from the power source to the switch
are not damaged. If the insulation is cracked or broken, immediately replace the cord
or cable.
• Connect the power supply to a different power source with a new power cord or power
cables. If the power supply status LEDs indicate that the power supply is not operating
normally, the power supply is the source of the problem. Replace the power supply
with a spare.

Troubleshooting Line Cards in EX9200 Switches
Problem Description: Line card is not functioning normally.
Solution • Monitor the LED labeled OK on the craft interface as soon as a line card is seated in an
operating switch.
The Routing Engine downloads the line card software to it under two conditions: the
line card is present when the Routing Engine boots Junos OS, and the line card is
installed and requested online through the CLI or the button on the front panel. The
line card then runs diagnostics, during which the OK LED blinks. When the line card is
online and functioning normally, the OK LED is lit green steadily.
• Make sure the line card is properly seated in the midplane. Check that each ejector
handle has been turned clockwise and is tight.
• Check the OK/FAIL LED on the line card and OK and FAIL line card LEDs on the craft
interface. When the line card is online and functioning normally, the OK LED is lit green
steadily.
• Issue the show chassis fpc command to check the status of installed line cards. As
shown in the sample output, the value Online in the column labeled State indicates
that the line card is functioning normally:
