Install a PA-7000 Series Firewall Network Processing Card (NPC)

You can install up to 6 NPCs in a PA-7050 firewall and up to 10 NPCs in a PA-7080 firewall to expand port density and throughput. On a PA-7050 firewall, you install NPCs in slots 1, 2, 3, 5, 6, and/or 7 and on a PA-7080 firewall, you install NPCs in slots 1, 2, 3, 4, 5, 8, 9, 10, 11, and/or 12. If you install two or more NPCs, review Configure Session Distribution on a PA-7000 Series Firewall to understand how the firewall distributes sessions and to determine the best policy to use based on your environment.
If you install an NPC in slot 1, the system configures ethernet1/1 and ethernet1/2 as a virtual wire. If you install an NPC in any other slot, the system does not apply a default configuration.
If you plan to populate all NPC slots on the firewall, ensure that you install the appropriate number of power supplies (see Determine PA-7000 Series Firewall Power Configuration Requirements).
The procedures to install NPCs in a single chassis and the procedure to install NPCs in a pair of chassis in high availability (HA) are different.
If you enable log forwarding (for syslog or WildFire for example), you must configure one port on an NPC with the type Log Port as described in Configure a Log Card Port on a PA-7000 Series Firewall.
