Replacing a hot-swap power supply
After you replace a power supply, verify that the power-supply status indicators (AC
Power LED and DC Power LED) are on, indicating that the power supply is
operating properly.
Notes:
1. You do not need to switch off the power to the appliance to install hot-swap
power supplies.
2. When replacing a power supply, do not remove the power supply until you are
ready to install its replacement.
To replace a hot-swap power supply:
1. Remove the power supply that you want to replace.
2. Install the replacement power supply in the bay:
a. Place the handle on the power supply in the open position (that is,
perpendicular to the power supply) and slide the power supply into the
chassis.
b. Gently close the handle to seat the power supply in the bay.
3. Plug the power cord for the power supply you just installed into the power cord
connector.
4. Route the power cord through the cable-restraint bracket.
5. Plug the power cord into a properly grounded electrical outlet.
6. Verify that the DC Power LED and AC Power LED on the power supply are on,
indicating that the power supply is operating correctly.
