MX960 High-Voltage Second-Generation Universal (HVAC/HVDC) Power Supply Description

The MX960 can be powered by four high-voltage second-generation universal power supplies (MX960-PSM-HV). The MX960-PSM-HV supports high-voltage alternating current (HVAC), or high-voltage direct current (HVDC.) The MX960-PSM-HV power supplies must be installed in adjacent slots in the chassis. The MX960-PSM-HV (HVAC/HVDC) power supply has one power inlet on front panel of the power supply rated at 30 A. The inlet requires a dedicated 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 High-Voltage Second-Generation Universal (MX960-PSM-HV) Power Cord Specifications for the MX960 Router for more details.

The MX960-PSM-HV (HVAC/HVDC) power supply configurations are zoned meaning that certain components in the MX960 chassis are powered by specific power supplies.

Figure 1 and Figure 2 illustrates MX960-PSM-HV (HVAC/HVDC) power supplies for the MX960.
