how to install Supermicro 1000W/1600W 1U Redundant Power Supply (PWS-1K62A-1R)

• Power down and prepare: Shut down the server and disconnect all power cables. If possible, enable maintenance mode in the server’s management interface to prevent unintended wakeups.
• Access the PSU bay: Remove the chassis cover or access panel that provides entry to the PSU bay. Ensure you are grounded to prevent static damage to sensitive components.
• Remove the existing unit (if replacing): If replacing an existing supply, disconnect its cables, release any retention latches, and slide the unit out carefully. Note the orientation and connector positions for reference.
• Install the new PSU: Align the PWS-1K62A-1R with the chassis rails and slide it into the PSU bay until it seats firmly. Engage any retention mechanisms to secure the unit in place.
• Connect power and management cables: Attach the appropriate power input cables to the PSU and connect the PMBus or management cables to the server management controller if required. Route cables neatly to avoid obstructing fans and other components.
• Configure redundancy and test: If your deployment uses standby redundancy, ensure the second PSU is recognized by the system and configured for automatic failover. Power on the server and verify that the PSU is detected, fans are functioning, and power rails are within expected ranges. Use the PMBus interface to verify monitoring data and, if applicable, test a simulated fault to confirm failover behavior.
