Table C-1 describes the card cage slot assignments for printed circuit boards in the SPARCserver 690MP. The table vertically lists PCB slot priority assignments in order of descending priority. Horizontal slot designations "A", "B", "C", etc., correspond to the preferred location for the specific board, with "A" being the most desirable location. If the only designation is "A", the board MUST be placed in that slot. Boards must be installed in descending order starting with the system board.
Note - If the boards are not installed in the proper order, the system may lose performance or functionality.
Note - Slots 1 through 3 are non-VME slots; that is, they are reserved for memory boards only.
Table C-1 shows slot numbering and bus locations on the SPARCserver 690MP backplane. Figure C-1 shows the backplane jumper layout on the SPARCserver 690MP and Table C-2 and Table C-2 further describe backplane jumper locations and functions.

A total of eight VME based communication boards (MCP and ALM-2) may reside in the system at one time. The board types may be mixed, with the constraint that four MCP boards maximum may be installed in the system.
The Asynchronous Line Multiplexer-2 (ALM-2) shares VME interrupt vector assignments and address space with the Multiprotocol Communication Processor (MCP). Because of these possible conflicts, and a possible physical space restriction in the Data Center Cabinet, the following must be applied when installing an ALM-2 into a card cage that also contains MCPs.
-------------------------------------------------------------------------------
Installed Board Device Address (Hex) VME Vector Interrupt Assignment -------------------------------------------------------------------------------
1st Board (ALM-2 or MCP) 0x01000000 8b
2nd Board (ALM-2 or MCP) 0x01010000 8a
3rd Board (ALM-2 or MCP) 0x01020000 89
4th Board (ALM-2 or MCP) 0x01030000 88
5th Board (ALM-2 or MCP) 0x02000000 a0
6th Board (ALM-2 or MCP) 0x02010000 a1
7th Board (ALM-2 or MCP) 0x02020000 a2
8th Board (ALM-2 or MCP) 0x02030000 a3
-------------------------------------------------------------------------------
As you can see from the table, the vector interrupt assignments of the ALM-2 and the MCP are the same. This makes the following instructions necessary.
When installing the ALM-2 or MCP, the boards must be installed in proper address order. Four VME board address positions are available that can accommodate ALM-2 or MCP board (devices 0-3). Therefore, one address position can only accommodate one board type, and any MCP or ALM-2 must be installed in the proper board device sequence.
Table C-5 Board Device Sequence
-----------------------------------
1st Board (ALM-2 or MCP) Device 0 2nd Board (ALM-2 or MCP) Device 1 3rd Board (ALM-2 or MCP) Device 2 4th Board (ALM-2 or MCP) Device 3 5th Board (ALM-2 or MCP) Device 4 6th Board (ALM-2 or MCP) Device 5 7th Board (ALM-2 or MCP) Device 6 8th Board (ALM-2 or MCP) Device 7 -----------------------------------
Note - Refer to the specific ALM-2 or MCP Configuration Procedure for information on board device addressing.
Example: If two MCP boards are already installed (1st and 2nd MCP boards) and you then want to install two ALM-2 boards, you must configure and install the two ALM-2 boards as the 3rd and 4th ALM-2 boards respectively.
ALM-2 and MCP must not be installed using identical VME addresses (board device numbers).
The ALM-2 board number (VME Address) is hardware selected on the board. If necessary, refer to the ALM-2 Installation and Configuration Manual, PN 813-1029 for information on setting/verifying the ALM-2 board address (board address selection is identical for the MCP).
ALM-2 and MCP boards occupy the identical VME address space as well as interrupt vectors, and both are known to the system board as mcpx (where x is a number 0 through 7). So, for example, if two MCP boards are already present in the card cage and you wish to add an ALM-2, the ALM-2 would be designated as mcp2 in the VME addressing (with the two MCP boards being designated mcp0 and mcp1 respectively).
