Replace a PA-5450 Data Processor Card (DPC)

Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator clip from the banana clip on the other end of the ESD grounding cable. Plug the banana clip end into one of the ESD ports located on the front of the appliance before handling ESD sensitive hardware. For details on the ESD port location, see PA-5450 Front Panel.
Push the front tabs on the DPC towards the center, prompting a click. This will cause ejector handles on the front of the card to rotate outward and unlock the card.
Grip the front ejector handles and gently pull the card out of its slot.
The below image shows a Management Processor Card (MPC); however, the procedure to install the DPC is the same.

With your replacement DPC in hand, rotate the card and align it with the front of the appliance so that the Palo Alto Networks logo is readable at the top of the card.
Gently push the replacement DPC into slot 2, 3, 4 ,5 or 6 until the card reaches the end of the slot. Push on both ejector handles until they lock the card into place.
