FAQs
What does 'hot-plug' mean?
Hot-plug means the power supply can be replaced without turning off or interrupting the system's operation.
What is the purpose of redundancy?
Redundancy provides a backup power supply, so if one fails, the other automatically takes over, preventing downtime.
How do I know if the L20 is compatible with my system?
Check your system's documentation or specifications to verify it supports hot-plug and redundant power supplies and that the L20's specifications match the system's requirements.
How often should I inspect the power supply?
It is recommended to inspect the power supply at least once a month for any visible signs of damage or wear.
Where can I find more detailed specifications?
Check the manufacturer's website or the system's documentation.
What should I do if the power supply fails?
If you have a redundant setup, the system should continue to operate. Replace the failed power supply as soon as possible. If there's no redundancy, follow the system's shutdown procedures to prevent data loss before replacing the unit.
Troubleshooting
System not powering on.
Check the power cable connection to the L20 and ensure it is securely plugged into a functioning power outlet. Verify the power supply's status indicators for any error signals. Consult the system's documentation.
Power supply fan is noisy.
Check for any obstructions near the fan. If the noise persists, it may indicate a failing fan, and the power supply might need replacing.
