Stack Power Cable for Catalyst 3750-X

This 30 cm Cisco cable connects two compatible Catalyst 3750-X series switches for stack power sharing. It suits network administrators who need redundant power across a switch stack. The black cable carries a single power link between the dedicated stack-power ports on each unit.

Two Fixed Connectors Simplify Installation

The cord arrives with a connector at each end, so no field termination or extra adapters are required. Plug each end directly into the stack-power receptacle on supported 3750-X models such as the 24-port or 48-port variants. This reduces cabling time and eliminates loose connections in the rack.

30 cm Length Limits Placement Options

At 11.81 inches the cable only reaches between adjacent switches in the same rack shelf. Builds that separate stack members across multiple rack units or cabinets cannot use this spare. Verify the physical gap before ordering.

Questions about this item

Will the 30 cm stack power cable need periodic replacement?

The cable is a passive copper assembly with no moving parts or firmware, so it does not require scheduled replacement under normal use.

What is the first limit reached when the Catalyst 3750-X stack runs continuously?

The 30 cm length fixes the maximum distance between stacked switches, so physical spacing becomes the limiting factor before electrical capacity.

Does the 11.81 inch black power cord generate noticeable heat or noise during all-day operation?

As a simple power cord it produces no audible noise and only negligible warmth from normal current flow.
