Power supply units
Your system supports two hot-swappable power supply units (PSUs) in 1+1 redundant or 2+0 non-redundant configurations.
CAUTION: Unsupported PSU configurations can result in a PSU mismatch condition and failure to power on.
NOTE: Ensure all PSUs are of the same rated output capacity, generation, and input voltage.
NOTE: Unsupported PSU configurations are two or more PSUs that do not share the same supported model, rated output
capacity, generation, or input voltage.
NOTE: The PSUs have internal fans that provide thermal cooling to these units. A PSU must be replaced if an internal fan
failure occurs.
Removing a power supply unit
Prerequisites
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by
your warranty. Read and follow the safety instructions that are shipped with your product.
CAUTION: Ensure that a power supply unit (PSU) is not operational at the time of its removal. Check the PSU
redundancy configuration before removing a PSU.
NOTE: The PSUs are hot-swappable. Remove and replace only one PSU at a time in a system that is turned on.
NOTE: You must remove a PSU to replace a faulty PSU, service other components of the system, or to reduce chassis
weight when installing the enclosure in the rack.
NOTE: To switch to a new PSU rated output capacity, generation, or input voltage, you must first power down the chassis
before changing the PSU configuration.
Ensure that you read the Safety instructions on page 33.
Steps
1. Disconnect the power cable from the power source and from the PSU that you intend to remove.
2. Press the release latch and slide the PSU out of the chassis.
