Replacing Power System Components

The power cords on all Services Routers are replaceable.

You can add a second power supply to the J6350 Services Router that is of the same type as the first (either AC or DC). The power supplies are located at the right rear of the chassis (see Figure 15 on page 28 and Figure 17 on page 29). Each J6350 power supply provides power to all components in the router. The J6350 power supplies are fully redundant. If one power supply fails or is removed, the remaining power supply instantly assumes the entire electrical load. One power supply can provide full power for as long as the router is operational.

Each J6350 power supply is hot-insertable and hot-removable.

CAUTION: Do not leave a power supply slot empty for more than a short time while the Services Router is operational. The power supply or a blank power supply panel must remain in the chassis for proper airflow.
