Status LEDs of a fabric in a Passport 20000

241-1501-200 5.2S2
For normal operation, the rectangular LED is solid green. See the figure
"Location of fabric status LEDs in a Passport 20000" (page 355).
In a startup mode after installation and powering up, the LEDs cycle from
solid red to solid green even if the firmware has not yet been loaded.
When the LED is red, the fabric status is one of the following:
• on the fabric the captive screw of the lever has not been fastened, which
depresses a switch to reset the fabric
• has failed and has automatically been disabled by the system
• has partially failed (may be green instead)
• is unseated
• is being reset
• is being initialized
When the LED is green, the fabric status is one of the following:
• is locked by force in software (unlike a CP or an FP)
• has failed partially and cannot transmit data
After normal operation when the LED is not green, do "What to do when a lit
red LED is detected" (page 344) or "What to do when a lit amber LED is
detected" (page 345).
