The Cisco C4KX-PWR-750AC-F= power supply is an essential investment for maintaining network uptime and reliability. Designed specifically for the Cisco Catalyst 4500-X series switches, this power supply ensures that your network equipment is provided with consistent, uninterrupted power. With its auto-ranging capability, the C4KX-PWR-750AC-F= adjusts to input voltages between 100 and 240 VAC, making it versatile and efficient for various electrical environments.

Equipped with a power factor correction (PFC) feature, the unit optimizes power consumption, leading to reduced electrical costs and enhanced power supply efficiency. The 750-watt output capacity can handle the switch’s demands even under heavy usage, ensuring that the network can support a large volume of traffic without power-related disruptions.

The compact size of 1.57 x 2.15 x 14.28 inches allows for a comfortable fit within your networking infrastructure, while a lightweight design of only 2 pounds ensures it won’t add significant bulk to your setup. Moreover, the device has a back-to-front airflow configuration, a critical feature for maintaining an optimal operating temperature. The airflow direction is clearly indicated by a blue color-coded release lever, which helps prevent incorrect installation and promotes efficient cooling.

Incorporated FAIL and OK LEDs provide quick, visual confirmation of the power supply’s status, enabling rapid troubleshooting should any power issues arise. The presence of a retention clip ensures secure attachment within the switch chassis, reducing the risk of accidental disconnection or movement.

In summary, choosing the C4KX-PWR-750AC-F= power supply for your Cisco Catalyst 4500-X series switch means investing in a power unit that promises efficiency, reliability, and ease of maintenance—a sound decision for any business’s network infrastructure.
