MX960 Power System Overview
The MX960 router uses either AC, DC, or universal power supplies. The power supplies connect to the
midplane, which distributes the different output voltages produced by the power supplies to the router
components, depending on their voltage requirements.
The MX960 router is configurable with one of these options:
Three or four normal-capacity AC power supplies
Up to four high-capacity DC power supplies
Up to four high-capacity AC power supplies
Up to four high-capacity second-generation AC power supplies
Up to four high-voltage second-generation universal power supplies
CAUTION:
simultaneously. The first type of power supply detected by the router when initially
powered on determines the type of power supply allowed by the router. All installed
power supplies of the other type are disabled by the router. If you install a power
supply of the other type while the router is operating, the router disables the power
supply and generates an alarm.
The router cannot be powered from AC and DC power supplies
