PA-7000 Series Firewall Module and Interface Card Information
The PA-7000 Series firewalls are modular systems and
requires a minimum set of front slot cards. The required cards include
the Switch Management Card (SMC), Log Processing Card (LPC) or Log
Forwarding Card (LFC), and at least one Network Processing Card
(NPC). To expand port density and throughput, you can install a
total of six NPCs in the PA-7050 firewall and ten NPCs in the PA-7080 firewall.
For details on installing front slot cards, see Install
the Mandatory PA-7000 Series Firewall Front Slot Cards.
Although all front slot cards have protection to prevent damage
if they are installed or removed when the chassis is powered on,
only the NPCs are intended to be hot‑swapped.
