Sun Fire[tm] 12K / 15K Server: Repair Procedures

This section provides the most common repair procedures for the Sun Fire 12K / 15K. The following links are located in the Sun Fire 15K System Service Manual (806-3512).

Clustered Hardware Note: When repairing a clustered system, you should replace server components by first switching over the data services to the functioning server, halting the host to be serviced, powering down the host, and then performing the hardware procedure to replace the component. Following the procedure, the logical hosts should be switched back to the default masters.

FRU Replacement Procedure Note: Sun Fire 15K/12K failure logs must be returned with defective FRUs to ensure correct problem diagnosis and FRU repair. When returning F15K and F12K FRUs which have functionally failed, the appropriate files must be captured and sent to this alias: F15K_F12K_RMA@sun.com. See FIN I0847-1 for details.

The following table provides the page numbers for each procedure.

Component	Section	Tips

CPU Board DIMM (Slot 0)	2.3.4	A special procedure must be followed when replacing this FRU (details). Too many Memory DIMMs are being unnecessarily replaced on UltraSPARC III family of systems utilizing NG-DIMM memory (FIN I0760-1).
CPU Filler Panel (Slot 0)	2.3.5
Cables (internal) AC Power Cord Internal Cabinet Cable 48 VDC Power Cable Power Shelf I2C Cable Power Crossover Cable Fan Tray Power Cable Internal Cable Harness Set Top Cap FrameManager Cable	2.10 2.10.1 2.10.2 2.10.2.2 2.10.2.3 2.10.2.4 2.10.2.5 2.10.2.6 2.10.2.7
Centerplane Support Board	2.2.1	A special procedure must be followed when replacing this FRU (details).
DVD-ROM	2.2.6
Digital Audio Tape (DAT)	2.2.8
Disk Drive	2.2.7	On the System Control Peripheral board, the upper disk (target Id 3) connects to J2 SCSI backplane connector, and the lower disk (target Id 2) connects to J3 SCSI backplane connector.
Fan Backplane	2.7
Fan Tray	2.6	A special procedure must be followed when replacing this FRU (details). Sun Fire 15K & Sun Fire 12K Fan Tray Assemblies do not provide thermal cooling headroom for MaxCPU configurations (FCO A0196-1).
Hot-Swap PCI (hsPCI) Assembly (Slot 1)	2.3.6	A special procedure must be followed when replacing this FRU (details). Sun Fire 15K domains may panic due to problem with Schizo 2.2 ASICs on hsPCI I/O Boards (FIN I0820-1). LEDs may not light upon cold start (FIN I0826-1). Some pcisch driver panics on F15K systems are unrelated to failed hardware (FIN I0852-1). hsPCI boards having Schizo 2.2 ASICs can suffer a panic due to a timing race condition (FCO A0193-1).
I/O Filler Panel (Slot 1)	2.3.10
MaxCPU Board (Slot 1)	2.3.9	Issue with diagnosing of "send mondo" panics (FIN I0765-1)
Mechanical Components Side Panel Access Door Air Filter Kick Plate	2.12 2.12.1 2.12.2 2.12.3 2.12.4
PCI Cassette(Slot 1)	2.3.7	A special procedure must be followed when replacing this FRU (details). Some pcisch driver panics on F15K systems are unrelated to failed hardware (FIN I0852-1).
PCI Cassette Card	2.3.8	A special procedure must be followed when replacing this FRU (details). Some pcisch driver panics on F15K systems are unrelated to failed hardware (FIN I0852-1). UltraSPARC III systems may panic due to a conflict between the Schizo 2.4 ASIC and the GigaSwift Ethernet PCI Card (FIN I0874-1). PCI adapters in F12K/15K domains may intermittently fail following a reset, reboot or "setkeyswitch on" operation. (FIN I0877-1).
Power Centerplane	2.9	A special procedure must be followed when replacing this FRU (details).
Power Module	2.5	A special procedure must be followed when replacing this FRU (details).
Power Supply	2.4	A special procedure must be followed when replacing this FRU (details).
Sun Fireplane Interconnect Assembly	2.8
System Control (SC) Board	2.2.2	Sun Fire 15K System Controller should be configured with at least 2 Gbytes swap space (FIN I0748-1). All Sun Fire 15K systems running SMS 1.1 or SMS 1.2 do not have the osdTimeDeltas file in the file propagation list. If a failover occurs, this could result in a rollback of a domain's Time Of Day. Such a shift in time has unforseen effects on applications (FIN I0785-1). System Controllers (SCs) built prior to September 2002 may not be able to save a crash dump due to a misconfiguration issue (FIN I0878-1).
System Control (SC) Board cPCI Slot Installation	2.2.4
System Control (SC) CPU Board	2.2.3	A special procedure must be followed when replacing this FRU (details). When inserting a CP1500 CPU board firmware must be updated (FIN I0761-1) Mac address of SC can change when installing new CP1500 board, which will cause the system not to boot (FIN I0771-1)
System Control (SC) Peripheral Board	2.2.5	A special procedure must be followed when replacing this FRU (details).
System Expander Board	2.3.1	A special procedure must be followed when replacing this FRU (details). Due to a bug in the AXQ ASIC which resides on the System Expander Board of the F15K, a Solaris panic can occur if too many outstanding noncacheable Programmed I/O transactions are awaiting service (FIN I0763-1). Sun Fire 15K domains containing Expanders with hardware dash revision 16 or less may dstop due to bug 4505200 (FIN I0822-1). LEDs may not light upon cold start (FIN I0826-1). System Expander Boards having AXQ 6.0 ASICs may experience a deadlock condition (FCO A0192-1).
