Cisco CAB‑SPWR‑30CM – 30 cm StackPower Cable overview:

The Cisco CAB‑SPWR‑30CM is a 30 cm StackPower interconnect cable used to link compatible Cisco Catalyst switches so they can share and balance power supplies across a stack. It creates a common power pool, improving redundancy and efficiency in enterprise network environments.

✅ Key Features

•  30 cm Cable Length – Compact size for side‑by‑side switch stacking in the same rack.
•  StackPower Technology – Enables multiple Catalyst switches to share power supplies, reducing the impact of a single supply failure.
•  Power Redundancy & Load Balancing – Provides backup power and optimizes distribution across the stack.
•  Durable Construction – Designed to meet Cisco quality standards and withstand enterprise network conditions.
•  Easy Installation – Hot‑pluggable cable that inserts directly into the StackPower ports on supported switches.
•  Tidy Rack Install – Short length helps keep cabling neat and minimizes clutter.

How to Install Cisco CAB‑SPWR‑30CM

Power Off or Prepare Switches

Though StackPower cables are generally hot‑pluggable, it’s safer to power off the switches before installation.

Find the StackPower Ports

On the rear of each supported Cisco Catalyst switch, locate the StackPower port.

Connect Cable Ends

Insert one end of the CAB‑SPWR‑30CM into the first switch’s StackPower port.

Attach the other end into the StackPower port of the next switch.

Create the Power Stack

Continue connecting additional switches using these cables in the proper topology (ring or star) if more than two.

Power On and Verify

Turn on all switches and verify the StackPower status via CLI commands like: show stack-power

Compatibility

The Cisco CAB‑SPWR‑30CM is designed for switches with StackPower support:

Compatible Series:

• Cisco Catalyst 3750X Series
• Cisco Catalyst 3850 Series
• Cisco Catalyst 9300 Series (StackPower enabled models)

Note:

– Due to its short length, this cable is best for switches next to each other in the same rack. Longer distances should use longer StackPower cables (like CAB‑SPWR‑150CM).

Frequently Asked Questions (FAQ)

1. What is the CAB‑SPWR‑30CM cable used for?

It connects compatible Cisco switches in a StackPower configuration so they can share power supplies and improve redundancy.

2. What is the length of this cable?

The cable is 30 cm (0.3 meters) long — ideal for close‑positioned switches.

3. What technology does it support?

It supports Cisco StackPower, which pools power supplies from multiple switches into a shared resource.

4. Does this cable carry data too?

No — StackPower cables share power only. Data stacking requires separate StackWise cables.

5. Is it hot‑pluggable?

Yes, StackPower cables can typically be installed or removed without powering down switches — though careful planning is recommended.

6. Can this cable be used between different racks?

Due to its short 30 cm length, it’s best used for adjacent switches in the same rack. Longer cables are better for distant connections.

7. Does it improve power redundancy?

Yes — StackPower allows power from one switch’s supply to support others if a supply fails.
