IBM 39J2750 Oscillator Card, CCIN 28E4

39J2750 is IBM's oscillator card with CCIN 28E4. The POWER5 system parts catalog lists it in the processor parts table for the 9119-590 and 9119-595.

IBM marks 39J2750 as RoHS compliant and lists 39J0188 as the non-RoHS equivalent. The catalog row shows no failing function code.

In the same 590/595 group IBM lists the 60H2214 service processor card (CCIN 28DE), the 41U0371 multiplexer card (CCIN 28E6) and the 41V1642 system unit backplane (CCIN 28E1), as well as the 60H2598 and 60H2602 MCM processor kits.

Unlike several cards in that group, the oscillator card is not listed for the 9406-595, only for the two 9119 models.

IBM groups 39J2750 under processor parts for the 590 and 595 rather than under the bus parts heading, next to the MCM processor kits it serves in the same frame.

Fit check: the multiplexer card in the same frame is the 41U0371, and the service processor is the 60H2214. More 590/595 cards are on the IBM POWER5 server parts page.
