43W8671 IBM I/O Board Shuttle Assembly, System x3850 M2/x3950 M2 (7141)

43W8671 is the I/O board shuttle assembly for the IBM System x3850 M2 and System x3950 M2 machine type 7141. Types 7233 and 7234 take a different assembly, 44E4485; match the machine type before choosing between them.

On the I/O board side of the server, IBM's service parts include a cable kit that joins the Remote Supervisor Adapter II, SAS power, hot-swap PCI switch, dual USB ports, media interposer card, SAS 4x signal and front panel with light path diagnostics to the I/O board, plus a separate rear I/O shuttle, 44E4582. The ServeRAID-MR10k SAS controller installs only in the dedicated slot on the I/O board, with no cabling to the server and no rerouting of the SAS cables.

The SAS power, SAS 4x signal and operator information panel cables connect to the I/O board. When the server reports error 162 (device configuration error) or 163 (real-time clock error), the service steps include reseating the I/O board shuttle assembly and then replacing the parts one at a time, in the order shown, restarting the server each time.

The server is 4U high with seven PCI Express x8 half-length slots, five of them non-hot-swap and two hot-swap. It has six USB 2.0 ports, a Broadcom 5709 dual Gigabit Ethernet controller, a serial connector, SMP Expansion Ports, a baseboard management controller and a Remote Supervisor Adapter II. Other x3850 M2 service parts are listed under IBM Misc.
