MX960 Ethernet Services Router DC Power Supply Installation Instructions
DC Power Supply
In the DC power configuration, the router contains either two or four DC power supplies (see Figure 1 on page 2), 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. The DC power supplies in slots PEM0 and PEM2 provide power to the lower fan tray, DPC slots 6 through 11, and SCB slots 1 and 2. The DC power supplies in slots PEM1 and PEM3 provide power to the upper fan tray, DPC slots 0 through 5, and SCB slot 0.
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
