How to install Cisco Catalyst 4500-X 750W AC Back-to-Front Cooling Power Supply

Installing or replacing the 750W AC power supply in a Catalyst 4500-X chassis is a straightforward, non-disruptive process when performed according to best practices. Before you begin, verify that your chassis supports hot-swappable power supplies and that you have a properly rated 750W AC module ready. Follow these steps to install the power supply quickly and safely:

• Confirm compatibility and readiness: Ensure the Catalyst 4500-X chassis is the correct platform for this power supply and that you have the corresponding 750W AC unit. Check that your data center procedures permit hot-swappable replacements and that you have grounded yourself to prevent static damage.
• Identify the spare or failed PSU slot: Locate the power supply bay intended for the replacement unit. If replacing a failed PSU, confirm the indicator status on the existing module and gather the new PSU before proceeding.
• Remove the old module (if replacing): Release the retention latch and slide the existing power supply out of its slot with a straight, steady pull. Take care not to twist or force the unit, which could damage connectors or the chassis.
• Install the new PSU: Align the new 750W AC power supply with the slot and slide it in until it seats and the latch engages firmly. Ensure the connectors are fully seated and the unit is secured.
• Restore power and verify: Reconnect the AC cord(s) to the new supply, restore power to the chassis, and check the status indicators or management console to confirm the power supply is recognized as healthy and delivering power. If redundancy is configured, verify that the failover path is functioning as expected.
