All power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own internal

cooling system.

Unlike systems with previous MX960 AC supplies, the systems with MX Series high-capacity power supplies

are zoned. No current sharing between power supplies is needed with the upgraded system because the

redundancy changes from 3+1 per system to 1+1 per zone. For MX960 AC configurations, two zones are

present. Two adjacent power supplies need to be installed in the chassis with two feeds attached.

Two AC power cables are required when installing the high-capacity AC power supplies

or high-capacity second-generation AC power supplies.

Routers configured with DC power supplies are shipped with a blank panel installed over

the power distribution modules. Routers configured with normal-capacity AC power supplies

power supplies and the high-capacity second-generation AC power supplies also have a blank

panel installed over the power distribution modules.
