Replacement procedures

When replacing FRUs while the switch is running, be aware of electrical safety hazards.
The switch uses a modular, hot-swappable architecture, and supports FRUs. You can replace any of FRUs
when the switch is running.

Replacing a power supply

Follow the procedures shown in
bodily injury.
Power modules on a 10500 switch must be the same model. When the replacement power modules and
the power modules that are operating correctly are not the same model, power off the switch and
remove all power modules before replacement.
Add a circuit breaker to the power line for each power supply. Before replacing a power supply, turn off
its circuit breaker.
The power supply might be of high temperature. Remove it with caution.
To install the removed power supply to the chassis again, install it after the status LED on it is off.
After removing the power supply, if you do not install a new power supply, install a blank filler panel.
