PA-7050 Modules and Interface Card
Overview
This chapter describes the PA-7050 firewall modules and the interface cards that can be installed and
are serviceable. The minimum cards that must be installed to operate the PA-7050 firewall is one
Switch Management Card (SMC), one Network Processing Card (NPC), and one Log Processing Card
(LPC). You can install up to five additional NPC cards to expand port density and processing.
Important:
The left black slide latch that slides up to unlock the release lever on the NPC contains a
micro-switch that is used to power down the card for removal. Both latches (left/right) need to slide up
to remove the card, but only the left side contains the micro-switch. Do not slide the left latch up unless
you intend to power down and remove the card.
Although all front slot cards have protection to prevent damage if they are installed or removed when
the chassis is powered, only the NPC is intended to be hot-swapped during normal operation. The SMC
and LPC should only be installed/replaced when the chassis is powered off. For details on replacing
PA-7050 hardware components, see “Maintaining the Hardware” on page 43.
