PA-800 Back-Panel

The following images show the back panel of the PA-820 and PA-850 Series firewall and the table describes each back panel component. The only difference between the back panels of the two firewalls is that the PA-820 has one fixed power supply and the PA-850 firewall has two hot-swappable power supplies (the second power supply is for redundancy).
