IBM 74Y3878 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y3878 is a CEC clock pass-through card, CCIN 2BBC, the Flexible Service Processor clock-distribution module fitted to IBM’s Power 780 (9179-MHB) POWER7 server. It carries the reference clock signal between the CEC (Central Electronics Complex) drawers in a multi-drawer Power 780 configuration, a function that keeps the processors across separate drawers running in lock-step. Power 780 hardware of this generation remains in active enterprise service, and a genuine spare clock pass-through card such as this one is a routine requirement for restoring inter-drawer clock synchronisation after a fault, since a failed unit can prevent a multi-drawer system from initialising correctly. Specifiers should confirm the exact machine type and drawer configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks IBM Power Systems components to support ongoing server maintenance projects. Please contact our sales team for current availability and pricing.
