The MX960 requires special power supplies that are not interchangeable with the MX240,
MX480, or the MX2000 series routers. Two types of AC power supplies can be used:
normal-capacity or high-capacity. Each AC power supply has a corresponding AC
appliance inlet located in the MX960 chassis directly above the power supply. Additionally,
high-capacity AC power supplies have an AC appliance inlet on the power supply itself.
Each inlet requires a dedicated AC power feed and a dedicated 15 A (250 VAC) circuit
breaker. One power cord per feed is required. See

Normal-capacity and high-capacity AC power supply configurations are zoned meaning
that certain components in the MX960 chassis are powered by specific power supplies.
Normal-capacity AC power supply configurations have one overall zone that provides
power to all components in the MX960 chassis. High-capacity AC power supply
configurations have two zones that provide power to specific components in the MX960
chassis.
