separate available power sources, connect each
power supply to separate input lines—the second
power source will likely be available during a failure.
Step 1
For AC-input power supplies, confirm
that the power on the power supply is off.
For DC-input power supplies, turn off the
circuit breaker to which you will connect
power, and tape the breaker switch to the
off position.
Step 2
Hold the power supply by the handle and
place your other hand underneath it.
Caution
Use two hands to remove and
install power supplies.
Step 3
Place the power supply inside the bay, and
align it to go straight into the bay.
Step 4
Push the power supply back into the bay
until its front panel is flush with the
chassis rear panel.
