Lenovo 81Y7100 Power/Signal Cable is a dual-purpose interconnect designed for ThinkSystem server environments, supporting both power delivery and signal transmission in a single integrated assembly. The cable accommodates mixed-use deployments where separate power and data pathways streamline rack cabling. Compatible with Lenovo ThinkSystem x3250 M5, x3550 M5, and related generation servers, it integrates with standard 19-inch rack infrastructure and modular power distribution units. Typical applications include primary system interconnects, hot-swap module connections, and auxiliary power/signal routing in blade enclosures or dense server configurations. The assembly supports standard enterprise operating currents and signal frequencies without performance degradation over extended cable runs.
