Solution 1017647.1 : Sun Fire[TM] 12K/15K/E20K/E25K: incorrect character shown on SC's LED display

Applies to:

Sun Fire 15K Server
Sun Fire 12K Server
Sun Fire E20K Server
Sun Fire E25K Server
All Platforms

Goal

A field engineer discovered a "6" or a "b" on an System Controller's LED display.
Realizing this wasn't the normal state, he requested the resolution center to research this. The normal state of this LED display is "0" once the post and boot have completed.

Solution

If a CP1500 board is not updated to the proper Open Boot Prom (OBP) and SSCPOST version, then it will not respond properly as a F15K System Controller, but will have the characteristics of an off-the-shelf CP1500 board used in other Sun[TM] systems.

The proper OBP version (nSCOBPimg) for the CP1500 is 3.14.6, while the post firmware version (SSCPOST) is available in document:

Document 1003372.1: Fire[TM] 12K/15K/E20K/E25K servers: Firmware Revisions

Also note that the parameter post-on-sir was not available without the proper OBP version; check:

Document 1003552.1: Sun Fire[TM] 12K/15K/E20K/E25K: SC POST results: 'Power On Selftest not run on last reset'

SC display CP1500 board status:

LED Value       Description
---------       -----------
d               POST invoked
0               Normal operating system conditions
1               Initialize system BSS
2               Ecache tests
3               All basic tests for CPU, MMU and cache
4               Memory probe and initialization, all FPU basic, memory tests
5               All basic CPU I/O tests
6               All advanced CPU tests and all CPU error reporting tests
7               All advanced CPU I/O tests
8               All basic PCI I/O tests
9               All basic I2C,PCI-to-PCI Bridge, Symbios 875 SCSI controller
P               POST exits with status equal to pass
F               POST exits with status equal to fail
H-E-L-P         If SPOST fails and the system is waiting at the "ok" prompt, then the characters H,E,L and P are displayed in sequence at repeated intervals. A similar display is generated if boot fails and the system remains at the "ok" prompt for about two minutes

NOTE: The character "b" is normal output for a CP1500 used in other Sun platforms: the 7-segment LED should display a lower case "b" (for booted).
From OEM manual: "b Solaris boot has taken place"
