Cisco CAB-SPWR-30CM – 30cm Stack Power Cable Full Description
The Cisco CAB-SPWR-30CM is a 30 cm StackPower cable designed for Cisco Catalyst switches that support StackPower technology. It allows multiple switches to share power supplies by connecting their StackPower ports together, creating a common power pool across the stack. This improves power redundancy, load balancing, and overall energy efficiency in enterprise networks.
With its compact 30 cm (0.3 m / 1 ft) length, the cable is ideal for connecting switches that are installed directly next to each other in the same rack. It helps maintain a clean cable layout while ensuring reliable power distribution across stacked switches.
The cable uses Cisco’s proprietary StackPower connectors and supports both power sharing and redundancy modes, allowing switches to continue operating even if one power supply fails.
Key Features
- 30 cm Compact Design – Perfect for connecting adjacent switches in a rack.
- StackPower Technology – Combines multiple power supplies into a shared power pool.
- Power Redundancy – If one PSU fails, other switches can provide power.
- Efficient Power Utilization – Allows unused power from one switch to support another.
- High Reliability – Designed for enterprise network environments.
- Male-to-Male StackPower Connector – Direct switch-to-switch connection.
- Supports up to 3750W Power Transfer across stacked switches.
How to Install Cisco CAB-SPWR-30CM
Step 1 – Power Off Switches
Turn off all switches before installing the cable to ensure safe installation.
Step 2 – Locate StackPower Ports
Find the StackPower ports on the rear side of the Cisco Catalyst switches.
Step 3 – Connect the First End
Insert one end of the CAB-SPWR-30CM cable into the StackPower port of the first switch.
Step 4 – Connect the Second Switch
Attach the other end of the cable to the StackPower port of the second switch.
Step 5 – Create Power Stack
Continue connecting switches to create a power stack topology (ring or chain).
Step 6 – Power On Devices
Turn on all switches and verify the StackPower status through CLI.
Step 7 – Verify Configuration
Use the command: show stack-power
to confirm the power stack is working correctly.
