Option Card Fault at Option Port CN5-A
oFA01
Option not properly connected
• Turn off the power and reconnect the option card.
• Check if the option card is properly plugged into the option port. Make sure the card is fixed properly.
• If the option is not a communication option card, try to use the card in a different option port. If the
option card works properly in a different option port, CN5-A is damaged, and the drive requires
replacement. If the error persists (oFb01 or oFC01 occur), replace the option card.

• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
