    M10i Router Redundant Power Supplies

    The M10i router uses either AC or DC power. You can install up to four load-sharing power supplies at the bottom rear of the chassis. Figure 1 shows the M10i router power supplies and where they are installed in the chassis.

    The AC power supplies are fully redundant. If one power supply fails or is removed, the remaining power supplies instantly assume the entire electrical load. Two power supplies can provide full power for as long as the router is operational. Three power supplies are required for redundancy. Power supplies must be present in slots P/S 0 and P/S 1 for the router to operate.

    The DC power supplies are fully redundant. The DC power supplies in slots P/S 0 and P/S 1 can provide full power to the router. Likewise, the DC power supplies in slots P/S 2 and P/S 3 can also provide full power. The DC power supplies in slots P/S 2 and P/S 3 jointly serve as the backup to the DC power supplies in slots P/S 0 and P/S 1. Power supplies must be present in slots P/S 0 and P/S 1 for the router to operate.

    Note: AC and DC power supplies are required in slots P/S 0 and P/S 1 for the router to operate.

    The DC power supplies in slots P/S 0 and P/S 1 must be powered by dedicated power feeds derived from feed A, and the DC power supplies in slots P/S 2 and P/S 3 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
