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 Celestica is not covered by your warranty. Read and follow the safety instructions that came with the product.
Warning: Always comply with all electrostatic and thermal guidelines to prevent bodily injury and ensure a properly functioning system when performing hot-plug operations.
Note: Some power supply units are hot-swappable. A single power supply unit can be removed from a powered-on enclosure for a maximum period of 10 minutes. Beyond that time, the enclosure may automatically shut down to prevent damage.
