Replacing a power supply
This section describes the precautions and procedures for replacing a power supply.
Replacement precautions
Before you replace a power supply, read the following precautions carefully:
•
Strictly follow the procedures shown in Figure 1 and Figure 2 to replace a power supply to avoid
device damage or bodily injury.
•
Power supplies on a router must be the same model. The model of the replacement power
supply must be the same as the model of the power supplies that are operating correctly. If not,
disconnect the power supply and remove all power supplies 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 the
power supply is off.
•
After removing the power supply, if you do not install a new power supply, install a filler panel.
