You are ready to install the replacement power supply.

Removing a DC Power Supply

You can remove one power supply while the other one provides power to the switch.
To disconnect the power supply from its power cables, you must shut off the power from the power source
and then either disconnect a connector for the power cables or release each of three cables from the power
supply (requires a standard screw driver).
Step 1 Turn off the circuit breaker for the power feed to the power supply that you are replacing.
Be sure that the LEDs turn off on the power supply that you are removing.
Step 2
Remove the power cable from the power supply by doing the following:
• To remove an orange power cable connector from a 48-V DC power supply, do the following:
1. Push the orange plastic button on the top of the connector block inward toward the power supply.
2. Pull the connector block out of the power supply.
Step 3 Grasp the power supply handle while pressing the release latch towards the power supply handle.
Step 4 Pull the power supply out of the bay.
What to do next
You are ready to install a DC power supply in the open slot.

Installing an AC Power Supply

You can replace one power supply while the other one provides power to the switch.
Before you begin
• The power supply that you are installing must be capable of using the same airflow direction as the fan
trays installed in the same switch and it must use the same type of power source as the other power supply
installed in the same switch (do not mix AC and DC power supplies in the same switch).
