• Monitor the LED labeled OK on the cra interface as soon as a line card is seated in an operang
switch.
The Roung Engine downloads the line card soware to it under two condions: the line card is
present when the Roung Engine boots Junos OS, and the line card is installed and requested online
through the CLI or the buon on the front panel. The line card then runs diagnoscs, during which
the OK LED blinks. When the line card is online and funconing 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 ght.
• Check the OK/FAIL LED on the line card and OK and FAIL line card LEDs on the cra interface.
When the line card is online and funconing 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 funconing
normally:
user@switch> show chassis fpc

NOTE: The show chassis fpc command displays the status of the line cards.
For more detailed output, add the detail opon. The following example does not specify a slot
number, which is oponal:
