PA-7080 Back Panel (DC)

The following image shows the back panel of the PA-7080 firewall (with DC power supplies installed).
The only differences between the back panel AC model and the back panel DC model is that the DC model has two DC Power Entry Modules (PEMs) instead of two AC PEMs. Each DC PEM contains two terminal strips, which connect eight wires (4 red positive and 4 black negative). The DC PEMs are field replaceable. For information on replacing a DC PEM, see Replace a PA-7080 DC PEM and for descriptions of the back panel components, see PA-7080 Back Panel (AC).
