Netwerkkabel Cisco 3750X Stack InfiniBand/glasvezelkabel 0,3 m zwart

The Cisco 3750X Stack power/data cable (0.3 m, black) is a short, flexible cable that carries power and a data signal to provide a communications channel among switches in a StackPower configuration. It is compatible with Cisco Catalyst 3750-X and 3560-X series switches and with an external power switch (XPS). The cable ends are color-banded to indicate correct mating: StackPower cables use green and yellow bands, while XPS cables use red and yellow (with additional green/blue identification on some connectors). The cable supports stacking power connections alongside the data signalling needed to coordinate power sharing among stacked switches.

Advantages

The cable combines power and signalling conductors in a single, flexible jacket, simplifying cable routing in racks and reducing the number of separate power leads. Color-coded ends reduce the risk of incorrect connections when linking Catalyst 3750-X/3560-X switches and XPS units. Its short 0.3 m length is suitable for close-proximity connections inside racks or between adjacent devices.

Suitable for

• Connecting Cisco Catalyst 3750-X switches into a StackPower chain
• Connecting Catalyst 3750-X or 3560-X switches to an XPS unit
• Short-distance power and signalling links in rack-mounted switch deployments

How to use

Identify the cable type and the colour bands on each connector before installation. For StackPower use, plug the connector with the blue/green identification into the Catalyst 3750-X switch and the connector with the yellow band into the adjacent Catalyst 3750-X or XPS as required. For XPS-specific cables, ensure the connector with the red band mates with the XPS. Route the cable inside the rack to avoid sharp bends and secure it to prevent strain on the connectors. Verify physical seating and then power on devices following Cisco stacking and power guidelines.

Recommendations

Use the cable only for the intended StackPower/XPS interconnect on supported Catalyst 3750-X/3560-X switches and XPS units. Avoid excessive bending or tension, and follow Cisco’s documentation for stacking and power-supply combinations to ensure safe and reliable operation.
