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:
user@switch> show chassis fpc
Slot State
0 Online
1 Online
2 Online
3 Online
4 Online
5 Online
NOTE: The show chassis fpc command displays the status of the line cards.
For more detailed output, add the detail option. The following example does not specify a slot
number, which is optional:
