M320 Power System Description

 

The M320 router uses either AC power supplies (see M320 AC Power Supplies Description), isolated DC power supplies, or nonisolated DC power supplies (see M320 DC Power Supplies Description). 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. All power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own internal cooling system.

The M320 router is configurable with:

  • Two, three, or four AC power supplies

  • Two or four DC power supplies (either isolated or nonisolated)

Caution

Mixing AC and DC power supplies is not supported and prevents the router from powering on. You must ensure that all power supplies are the same model number.
