High-Capacity Second-Generation AC Power Supplies | 135
Understanding Input Mode Switch (DIP Switch) Settings | 136
Four types of AC power supplies can be used: normal-capacity, high-capacity, high-capacity
second-generation, and high-voltage second-generation universal power supplies (for more information
on the high-voltage second-generation universal power supplies, see MX960 High-Voltage Second-Generation
Universal Power Supply Description). Each of the high-capacity has a corresponding AC receptable located
in the MX960 chassis directly above the power supply. High-capacity second-generation have two AC
receptacles on the power supply itself. Each receptacle requires a dedicated AC power feed and a dedicated
breaker. For all power supplies the circuit breaker protection should be designed according to National
Electrical Code (NEC) or any similar local standard based on maximum drawn current of the power supply
specified in this document. See
more details.
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.
