Cisco CAB-SPWR-150CM-RF StackPower Cable 1.5m

The Cisco CAB-SPWR-150CM-RF is a specialized 1.5-meter StackPower cable engineered to facilitate reliable power interconnection between compatible Cisco Catalyst 3750X series switches. This high-quality cable is designed to enable stable power sharing and redundancy within a switch stack, ensuring that your network infrastructure remains operational and efficient. By allowing switches to pool their power supplies, this cable helps maintain continuous operation in demanding enterprise-grade networking environments.

Advantages

This cable provides a robust and flexible connection that carries both power and essential data signals, creating a reliable communication channel between switches in a power stack. Its design features keyed connectors with color-coded bands, which significantly simplifies the installation process and helps prevent incorrect connections. The cable is built to withstand the requirements of professional networking setups, offering a durable solution for managing power distribution across multiple units.

Suitable for

• Connecting Cisco Catalyst 3750X series switches in a power stack
• Interconnecting switches with an external power system (XPS)
• Establishing power redundancy in enterprise network racks

When it may not be suitable

This cable is specifically designed for use with the Cisco Catalyst 3750X series and certain XPS units. It is not compatible with other switch series or hardware that does not support the proprietary StackPower technology. Attempting to use this cable with incompatible equipment may result in connection failure or hardware damage.

Key specifications

• Length: 1.5 meters
• Connector type: Straight male to straight male
• Color: Black
• Compatibility: Cisco Catalyst 3750X series switches and compatible XPS units
• Function: Power and data signal transmission for StackPower systems

How to use

To install the cable, identify the color-coded bands on the connectors. The cable features specific color indicators to ensure proper orientation. For StackPower configurations, ensure the connector with the green band is inserted into the appropriate port on the Catalyst 3750X switch, while the yellow-banded end can be connected to either a switch or an XPS unit. Always ensure the equipment is powered down or follow your specific switch documentation guidelines before connecting or disconnecting power cables to avoid electrical hazards.

What to consider before purchase

• Verify that your specific switch model is part of the Catalyst 3750X series
• Check the required cable length for your rack configuration to ensure 1.5 meters is sufficient
• Confirm whether you are connecting to another switch or an external power system to ensure the correct cable type is selected

Usage recommendations

Always verify the color-coded bands on the cable ends before insertion to ensure the correct port is utilized. The blue-banded connector is strictly for Catalyst 3750X switches, while the yellow-banded connector is versatile for both switches and XPS units.
