M120 DC Power Supply Description
In the DC power configuration, the router contains two DC power supplies (see Figure 1), located in the right rear of the chassis in slots PEM0 and PEM1 (left to right). A single DC power supply provides sufficient power for a fully configured router.
Two DC power supplies share power almost equally within a fully populated system. If either power supply fails, the remaining power supply takes over without interruption.
Each DC power supply has a single DC input (–48 VDC and return) that requires a dedicated 60 A (–48 VDC) circuit breaker for the maximum router hardware configuration. .
