Jumper Settings

LOCATION	PINS	SETTING	DESCRIPTION
J4202	1-2 2-3	In In	Normal Real Time Clock (default) Clear Real Time Clock CMOS
J4204	1-3	Out	1-2=XIR 2-3=POR (default)
J4205	1-3 2-3	Out In	Flash Write Protected * Flash Write Enabled (default) *
J4206	1-2 2-3	In In	Select ROMBO Select Flash (default)
J4207	2-3 1-2	In In	Normal Flash (default) Flash Recovery
* Jumpering 1-2 has no effect because Pin-1 not connected.
The Flash PROM is write protected when: J4205 Pins 2-3 are Not jumpered, or the Keyswitch is in the Locked position
The Flash PROM is write enabled when: J4205 Pins 2-3 are jumpered, and the Keyswitch is in the Normal or Diagnostic position, and the PROM_SB_WE_N signal is software-enabled

Notes

1. The minimum operating system is Solaris 8 7/03.
2. FAB 270-6344-06 replaced 270-6344-05 on 501-6344 in July 2004.
3. 270-6344-07 was used to build 501-6344-09 in August 2004.
4. 270-6344-07 was used to build 501-6344-09 in October 2004.
5. 270-6344-07 replaced 270-6344-06 on 501-6344-10 in November 2004.
6. The 501-6900/540-6276 was released in May 2004 and inactivated in July 2004. It did not ship.
7. Motherboard 501-6910 (in assembly 540-6336) requires ALOM >=1.5.
8. Motherboard 501-7343 (in assembly 540-6682) requires ALOM >=1.5.4.
9. The 501-6344 includes OBP <4.15.1 with extended diagnostics disabled by default.
   The variable diag-level is set to min. The variable verbosity is not available.
10. The 501-6910 includes OBP >=4.15.1 with extended diagnostics enabled by default.
    The variable diag-level is set to max. The variable verbosity is set to normal.
11. The 501-7343 includes OBP >=4.16.4 with extended diagnostics enabled by default.
    The variable diag-level is set to max. The variable verbosity is set to normal.

Memory Notes

1. Bank, Rank, DIMM, and XOR Interleaving is supported.
2. UltraSPARC IIIi supports single bank and dual bank DDR DIMMs.
3. Two DIMMs of the same bank size (single or dual) and memory size form a bank.
4. The minimum requirement is two DIMMs in any Bank (B0/D0/D1 or B1/D0/D1).
5. Memory error reporting identifies a failing Bank, not a single failing DIMM.

Motherboard Notes

1. The Motherboard FRU includes Motherboard 501-6344, AC Wire Harness 530-3146, Flex Circuit Cable 530-3147, and CPU/Memory Shroud 540-5285.
2. Do NOT pull on AC Wire Harness connectors P9 or P10. The connectors attach sideways to the Motherboard and are held in place by the CPU/Memory Shroud.
3. The CPU/Memory Shroud holds Tomatillo heatsinks at U1501 and U2601 in place.
4. Master Tomatillo interfaces include the ALOM/RSM Slot, Ethernet 1, Flash PROM, I2C, ATA-100, PCI Slots 0, 1, and 3, SCSI, Serial B, Serial PROM, Smart Card Reader, TOD, and USB 0-3.
5. Slave Tomatillo interfaces include Ethernet 0, and PCI Slots 2, 4, and 5.
