SRX5800 Services Gateway DC Power Supply

In the DC power configuration, the services gateway contains either two or four DC power supplies (see Figure 16), located at the lower rear of the chassis in slots PEM0 through PEM3 (left to right). You can upgrade your DC power system from two to four power supplies.

Four power supplies provide full redundancy. If a DC power supply fails, its redundant power supply takes over without interruption.

Each DC power supply has a single DC input (–48 VDC and return) that requires a dedicated 80 A (–48 VDC) circuit breaker for the maximum hardware configuration.
