how to install Extreme Networks 920W Power Supply

• Prepare the workspace and confirm compatibility with your Extreme Networks 5420 PoE switches. Ensure you follow your organization’s electrical safety practices and ESD precautions before handling the PSU.
• Power down the switch if your deployment requires non-hot-swappable conditions or if your design calls for a controlled maintenance window. In compatible configurations, you may proceed with hot-swapping without powering down the entire system.
• Access the PSU slot in the switch chassis. Remove any existing module by releasing the latch and carefully pulling the unit straight out, taking care not to disturb other components.
• Insert the 920W AC PoE Power Supply into the slot, aligning connectors and seating the unit firmly until the latch engages. Ensure the PSU is firmly seated and secure before proceeding.
• Connect the AC power cord to the PSU and plug the other end into a grounded electrical outlet. Route cables to promote airflow and avoid obstruction near fans or vents.
• Power on the switch (or verify the PSU if power is already supplied). Check the PSU status indicators and the switch management interface to confirm healthy operation and proper power delivery to PoE devices.
• In systems with redundant PSUs, verify that both power supplies are recognized by the switch and that failover behavior is configured according to your HA design. Monitor the management console for alerts or fault conditions.
