How to install Extreme Networks 150W AC Power Supply

• Power down the chassis according to your facility’s procedures and unplug the AC input before handling the power supply to prevent electrical shock or damage.
• Identify the dedicated PSU slot in the Extreme Networks 5420 switch chassis intended for the 150W AC power supply. Confirm that you are installing the non-PoE compatible module in the correct slot to maintain proper operation.
• Remove the existing power supply (if applicable) with care, using the chassis’s standard release mechanism. Keep the removed module upright to prevent any components from touching conductive surfaces.
• Align the new 150W AC power supply with the slot rails and slide it into the chassis until it engages with a secure click. Verify that the module is seated fully and the retention mechanism is engaged to prevent accidental removal during operation.
• Reconnect the AC power cord to a properly grounded outlet and route the cord through the chassis cable management area to minimize strain and interference. Restore power to the switch and monitor the indicators for normal operation.
• Power on the switch and verify that the new PSU is detected, showing healthy status indicators and stable voltage rails. If applicable, perform a brief load test to ensure the supply maintains regulation under typical operating conditions.

Frequently asked questions

• Is this power supply compatible with PoE configurations? No. This 150W AC Power Supply is designed specifically for non-PoE 5420 switches. For PoE deployments, select the appropriate PoE-capable power supply recommended by Extreme Networks for your model and workload.
