6. Check the LEDs on the SFB faceplate to verify that it is functioning normally.
•
The green OK/FAIL LED should light steadily a few minutes after the SFB is installed.
•
If the OK/FAIL LED is red, remove and install the SFB again. If the OK/FAIL LED still lights steadily,
the SFB is not functioning properly. Contact your customer support representative. See “Contacting
Customer Support” on page 705.
7. Check the status of the SFB by using the show chassis environment sfb command:
user@host> show chassis environment sfb
