The failure or removal of a system module (I/O card)

Check and confirm the status of the affected card:

• DDCLI (SSH) # system show hardware
  • A failed or removed card slot reported as '(empty)' 
  • Example:
    

    sysadmin@DD# sys show hardware
    Slot   Vendor   Device                            Ports

    • This example show slot 7 as (empty) as the card in that slot had failed.

• • This output can be compared to Auto-Support to determine the missing card if all slots are not populated.

If the card was removed accidentally:

• Power off the DD unit, DDCLI (SSH): 

  • # system poweroff

• Reinstall the card as needed
• Power the system back on.

If the card is suspected to be faulty or failed, contact your Support Provider to investigate and arrange a repair or replacement.
