SPARCengine Ultra AXmp

Notes:

1. SPARCengine Ultra AXmp motherboard assembly is comprised of Complex A & B boards, System Control board, Compute Module, and System Base Board.
2. Four-way multiplexing.
3. Uses up to four UltraSPARC I or II 167 MHz to 300 MHz processors.
4. Operates under Solaris 2.6  HW:3 (5/98) and later
5. Support up to 2 GB memory on-board (64MB minimum).
6. Six PCI slots.
7. Autosend 10BASE-T or 100BASE-T Ethernet.
8. Ultra AXmp motherboard assembly part number, serial number, revision number (last two digits of part number), and date code (assembly period: week, year: 0798) are located on stickers on the top of the CPU Complex A Board.

Notes:

1. UltraSPARC I or II module part number and serial number are located on stickers on the side of the CPU module.
2. 1, 2, 3, or 4 CPU modules can be installed.
3. CPU modules used in a particular configuration must be the same type and have identical speed, external cache, and power.
4. CPU modules available for use with the Ultra AXmp:

Notes:

1. With multiple CPUs, first CPU to respond to OBP probe during boot process becomes master processor for system.
2. Fewer than four CPU modules in system, modules can be inserted into any of the four slots - there is no required slot assignment.
3. Two CPUs in system gives better performance by installing one module into slot in CPU Complex A and the other CPU module into one of the slots in CPU Complex B.

Notes:

1. Fans should always be on a full speed (+12V).
2. Fans must be 12 VDC, variable speed with sensor feedback to detect a failed fan.
3. Recommended fan is NMB: Model 4710NL-04W-B59 Rib type.
4. Sun recommends fans to be mounted directly to Ultra AXmp motherboard assembly chassis for best cooling action.
   Caution - Fans are not included with the motherboard assembly and must be supplied by the OEM. Failure to provide adequate cooling to the CPU modules will cause damage to these CPU modules.
5. Required fans use jumpers J1003 and J1004.
6. Optional fans use jumpers J1005 for PCI slots and J1006 for disk drives and power supply.

Notes:

1. CPU Complex A Board is part of Compute Modules.
2. Holds up to two CPU modules and has jumper (J0302) related to CPU type.
3. Architecture complies with SPARC V9 instruction set.
4. All processors must operate at same clock frequency.
5. Each processor slot is supported by a DC-to-DC converter module, located on the CPU Complex Board.
6. CPU Complex A Board Jumper Settings:

Notes:

1. CPU Complex B Board is part of Compute Module
2. Holds up to two CPU modules and has jumper (J0302) related to CPU type.
3. CPU Complex B Board Jumper Settings:

Notes:

1. Complex A/B Board Jumper, J0302, determines whether UltraSPARC I or UltraSPARC II processor is to be used.

Notes:

1. System Control Board holds up to 16 DRAM DIMMs organized as two banks.
2. Contains memory control logic and bus crossbar control logic.

Notes:

1. System Control board has two jumpers (J2301 and J2301) related to the CPU speed.
2. System Control Board Speed Jumper Settings:

Notes:

1. Compute Module contains the System Control Board which holds 8 or 16 system memory DIMMs.
2. Eight memory DIMMs in a bank; two DIMM banks for total of 16 sockets.
3. Minimum memory required 64MB; maximum memory supported 2GB.
4. 16 sockets, 2 banks, 8 DIMMs per bank.
5. DIMMs in same bank must be of same size, configuration, and speed.
6. Can mix one bank of 10-bit column address DIMMs with one bank of 11-bit column address DIMMs.
7. Sun recommends all DIMMs in a bank be from same manufacturer.
8. Uses DRAM, EDO, Buffered, 10 or 11 bit Column Address, 3.3V, 60ns or less, 72bits, 168 Pins, DIMMs.
9. Memory must be installed 8 DIMMs at a time.

Single and Dual Bank DIMM Usage (256MB DIMMs)

Notes:

1. Uses up to two 66 MHz 64-bit PCI cards and up to four 33 MHz 64-bit PCI cards.
2. Has connectors and headers for connecting Ultra AXmp motherboard assembly.
3. Jumpers J0703, J0704, and J1002 control serial port and power on/off operation.
4. Contains Ultra Port Architecture (UPA) chips and all of input/output controllers and interfaces.

1. Header Summary for SPARC engine Ultra Axmp
   

Notes:

1. Ultra-wide SCSI interface (SYM53C876) provides:
   • 68-pin UW connector on rear panel for external devices; up to 15 devices
   • 68-pin UW connector J1801 for internal devices; up to 15 devices
   • 50-pin narrow connector J1802 for internal devices; up to 7 devices
2. Ethernet 10/100 BASE-T uses RJ-45, 8-pin connector.
3. PCI Connectors provide 94-pin PCB edge connectors; accepts long or short card; supports up to 25W per slot.
4. Two UPA-to-PCI bridge chips provide four PCI buses (6 PCI slots).
   • six 64-bit PCI slots (two 66MHz, four 33MHz).
5. PCI slots 7, 8, and 9 are not used because they are covered by the Compute Module.
6. Sun keyboard/mouse interface uses:
   • Type 5 keyboard (UNIX) 320-1234, mouse X494A

7. PS/2 Keyboard interface is 6-pin DIN type connector, J0501
8. When both the Sun and PS/2 keyboards are present, the system chooses the PS/2 keyboard as system input device unless the factory default has been overridden.
9. PS/2 Mouse interface is 6-pin DIN type connector, J0502
10. Parallel port interface uses DB25S female connector on rear panel, J0601, and is IEEE compatible.
11. Serial port interface uses DB25P male, wired for TTY-A and TTY-B.
    • Need "Y" splitter cable to use TTY-B.
