Cisco C3KX-PS-BLANK Power Supply Blank | Catalyst 3560-X Accessory UK

Cisco C3KX-PS-BLANK is a Power Supply Blank for Catalyst 3560-X and 3750-X switches. Maintains airflow, protects internal components, and supports reliable enterprise network performance. 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.

Why the blank matters. A blank is not an optional extra. A chassis is cooled by air drawn through a continuous path, and an empty slot lets that air escape where it is not wanted, so the boards that are fitted run hotter than they should. Slots left open long enough will show up as thermal alarms or a shutdown that looks like a board fault. Blanks are the first thing discarded during a rebuild and the hardest to source afterwards, which is why they are worth ordering with the chassis rather than after it.
