IBM 74Y9391 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y9391 is an 80mm single fan assembly, a genuine cooling FRU for IBM POWER7 systems including the 9179-MHB, MHC and MHD, and the 9117-MMB, MMC, MMD and EAD models. It fits a dedicated fan bay within the system chassis, supplying part of the airflow needed to keep the processor and memory subsystems within their operating temperature range, and systems of this class are typically fitted with several such fans working together for redundancy and hot-swap serviceability. A single failed fan does not normally take a redundant system down, but replacing it promptly restores full cooling margin and avoids the increased risk of a thermal event if a second fan later fails. Genuine IBM fan assemblies of this kind are a routine requirement for maintaining an established POWER7 deployment’s cooling redundancy. Specifiers should confirm their exact system model before ordering, since fan assemblies are not universally interchangeable across the POWER7 range.
