MX480 Power System Description
TheMX480 routeruses either ACor DC power supplies. The MX480 router is configurable
with two, three, or four AC power supplies or two or four DC power supplies. The power
supplies connect to the midplane, which distributesthe different output voltages produced
by the power supplies to the router components, depending on their voltage requirements.
Each power supply is cooled by its own internal cooling system.
CAUTION: The router cannot be powered from AC and DC power supplies
simultaneously.
Redundant powersupplies are hot-removable and hot-insertable,as described in “MX480
Field-Replaceable Units (FRUs)” on page 247.
CAUTION: When you remove a power supply from a router that uses a
nonredundant power supply configuration, the router might shut down
depending on your configuration.
NOTE:
Enhanced AC and DC power supplies are an upgrade for the MX480 router,
and satisfy power requirements for higher-density DPCs. When upgrading to
enhanced power supplies, always upgrade power supplies in adjacent slots.
