IBM 17P8102 Fan Sense 3 to Fan Sense 2 Cable adapter enables thermal monitoring compatibility between IBM server generations. This cable bridges Fan Sense 3 connectors to legacy Fan Sense 2 hardware, allowing older cooling control systems to integrate with newer management infrastructure. Typical applications include mixed-generation server deployments, cabinet refreshes, and thermal system upgrades where legacy fan sensing equipment must remain in service. The cable supports standard IBM environmental monitoring protocols and integrates with RSA II and System x management interfaces. Compatibility spans IBM System x and blade server platforms that use either sensing standard. Part number 17P8102 is a passive adapter requiring no additional power or drivers.Tested and guaranteed; available via quote from G5 Network Group.
