Cisco C3K-PWR-750WAC Power Supply | 750W AC PSU for Catalyst Switch UK
Cisco C3K-PWR-750WAC 750W AC power supply for Catalyst 3750-E and 3560-E switches. Hot-swappable PSU for reliable enterprise networking.
Cisco C3K-PWR-750WAC is a 750W AC Power Supply for Catalyst 3750-E and 3560-E switches. Hot-swappable PSU for reliable enterprise networking. Identify it by part number rather than appearance: parts in this class frequently look the same across generations that will not work in each other’s place.
Size it for the load, not the box. The common mistake is choosing a supply that covers the chassis and forgetting everything hanging off it. On a PoE switch the powered devices draw through the same supply, and a fully loaded access switch can need several times the chassis figure. Check the input type against the rack, and match airflow direction if a second unit is going in alongside.
