SPARCengine Ultra AXi

Ordering Note:

1. When ordering an Ultra AXi motherboard, specify which CPU module is to be used. They must be ordered simultaneously.

Notes:

1. Operates using Solaris 2.6 and later.
2. Ethernet 10/100 BASE-T Interface uses RJ-45, 8-pin connector.
3. Uses UltraSPARC II/i processors.
4. Main memory modules require 32MB minimum.
5. Internal devices use Ultra-wide SCSI interface, J1001, connector.
6. Serial number, version number, and date code are found on stickers located next to the internal SCSI connector (J1001).
7. Six 32-bit PCI slots are available, three in Bus A and three in Bus B. All slots are 33MHz, 32-bit, 5V only.
8. If the FFB2 board is used, it blocks one PCI slot, making it unusable.

Jumpers

Jumper	Settings and Results
J1401	1-2 Flash Memory Write disabled 2-3 Flash Memory Write enabled (default)
J1402	1-2 Flash Memory selected (default) 2-3 ROM Emulator selected (used for system debug only)
J1804 J1806	1-2 RS232 (default) 2-3 RS423 1-2 RS232 (default) 2-3 RS423
J1805	1-2 FAST Serial 2-3 Normal RS232 (default)

Notes:

1. Most types of PS/2 keyboards (J2501) and PS/2 (J2500) mouse devices are supported.
2. Two 3-pin connectors, J3602 and J3603, power two optional fans from the motherboard. Fans must have variable power conditions for speed control and must have TTL level signal to indicate rotation or not.
3. Only assert the push button reset, J1501, at the "OK" prompt or if maintaining the state of the disks is not critical.

Notes:

1. Memory modules are installed in pairs (two DIMMs at a time).
2. Uses DRAM, EDO, Buffered, 10 or 11-bit Column Address, 3.3V, 60ns, 72-bit, 168-pin DIMMs.
3. Both DIMMs in a pair must be of the same size.
4. Each DIMM Pair of 2 sockets must have identical DIMMs installed.
5. It is possible to have from 32MB to 1GB populated (32MB, 48MB, 64MB, 80MB, 96MB, 112MB, 128MB...up to 1GB in 16MB increments.)
6. Memory organization of 10-bit column address is supported in all DIMM Pairs.
7. Memory organization of 11-bit column is supported in DIMM Pairs 0 and 2 only.
8. Memory DIMMS (J0301-J0304, J0401-J0404)

Notes:

1. Uses Ultra-wide SCSI interface with 68-pin UW connector rear panel for external devices.
2. Parallel port uses DB25S female connector and is IEEE 1284 compatible.
3. Serial port uses DB25P male connector wired for TTY-A and TTY-B. Need "Y" splitter cable to use TTY-B.
4. Standard Ultra AXi motherboard supports the Sun type 5 keyboard and mouse.
5. Keyboard/Mouse Adapter brings signals to rear panel for PS/2 keyboard and mouse.
6. Interface connectors on the motherboard are J2500 for the PS/2 mouse header and J2501 for the keyboard header.
7. Ehternet uses twisted pair type with RJ45 connector at the rear panel.
