    Cardcage configuration tables
    -----------------------------

   How to use the cardcage configuration tables:

   Boards are listed in order of priority, from top to bottom. If two
boards would prefer to be installed in the same slot, whichever board is
toward the top of the table wins, unless the lower board cannot be
installed in any other slot.

   Many boards can be installed in any of several slots. The most
desirable slot is indicated with "A", the second most desirable with
"B", and so on.

   Note that many boards are unfortunately not listed. Also note that
these are only the official Sun-recommended board orders (except where
specifically noted); in many cases boards will work in other slots.
Consult the listings for the individual boards. Note that memory boards
usually need to be in the recommended positions, since there is usually
a special memory bus in the backplane to which all memory boards must
connect.

   Note that the configurations below represent the cardcage tables
dated 6/8/88. Sometimes there are major changes in preferred slots
between cardcage table revisions. If you think you need an older version
(5/13/87 is available), send me email (remind me that 5/13/87 is in
revision 1.1 of part 7, please).

VME

   Note that VME cards frequently have "springfingers" on their rear
edges, metal strips that are installed between the edge of the PC board
and the outer panel to reduce RFI emissions, with serrated metal
"fingers" protruding from either side of the strip. If a board with
springfingers is installed next to a board without springfingers, there
must be a plastic insulator shield over the fingers on the side toward
the fingerless board, to prevent possible shorting of component leads to
the springfingers.

   VME cardcages (except for the 2/50 and the 3/75) also have jumpers on
the backplane itself, one set per slot, which must be set appropriately
for the board in the corresponding slot. These jumpers are marked Px0y,
where x is the number of the slot and y is the number of the jumper.
Jumpers Px00, Px01, and Px02 must always be installed in normal use.
Jumpers Px03 (BG3) and Px04 (IACK) are installed according to the board
in the slot, and always installed for empty slots. Note that 2/130 and
2/160 systems shipped before 11/1/85 did not have these jumpers
installed by default. The highest-numbered slot is usually (always?)
missing Px04. Note that the jumpers are usually (always?) on the
opposite side of the backplane from the VME connectors and are usually
(always?) accessed via a panel in the front of the machine.

        ~~ The 501-1383 TAAC-1 consumes three spaces (slots 10, 11, and

           not exist).


IMPORTANT NOTE ABOUT ALM AND MCP PRODUCTS

   The 501-1203 ALM-2 shares VME vector interrupt assignments with the
501-1157 (-1165 also?) ALM-1 and the 501-1221 MCP. The ALM-2 also shares
VME address space with the MCP. There may also be a problem with
physical space in the chassis.

   If three ALM-1s with their associated MUX boxes are already
installed, there is no room to mount the ALM-2's Device Connector
Assembly (DCA). Fortunately, it is possible to mount the DCA to the
wall, floor, or anywhere else convenient.

   The ALM-2 and the MCP have exactly the same vector interrupt
assignments. The ALM-1 has vector interrupt assignments that occupy the
same range but are in the opposite order, as shown below:

        board number    device entry    ALM-1 vector    ALM-2/MCP vector
        ------------    ------------    ------------    ----------------
            1st              0              0x88            0x8B
            2nd              1              0x89            0x8A
            3rd              2              0x8A            0x89
            4th              3              0x8B            0x88

   To avoid conflicts, follow these rules:

   1) No more than four ALM-1, ALM-2, or MCP boards total may be
installed in a single cardcage.

   2) When installing ALM-2s or MCPs, the boards must be installed in
the proper address order, counting all boards of either type previously
installed. This ensures that no ALM-2s or MCPs will attempt to use the
same vector interrupt. For example, if an ALM-2 is installed and you
wish to install an MCP, it must be installed as the *second* MCP, not
the first. If it is installed as the first, it will attempt to use the
same vector interrupt as the existing ALM-2.

   3) Because the ALM-1 vector interrupt assignments are the reverse of
the others, any ALM-1 boards must be installed in their normal order,
counting *only* ALM-1s. This ensures that as long as no more than four
boards total of any of these kinds are installed, the ALM-1s will never
use the same part of the range as the ALM-2s and MCPs.

   4) Additionally, the ALM-2 and MCP occupy identical addresses in the VME
address space, and both use /dev entries of mcp0 through mcp3. Each
additional board installed uses the next available entry, regardless of
the type (ALM-2 or MCP, but not ALM-1) of the boards installed
previously. The addresses must also be set (via jumpers or switches?) on
the boards -- as stated in rule 2, the board must be installed counting
all boards of either type previously installed.

   5) For deskside systems that support the ALM-1, only one such board
may coexist in the cardcage with ALM-2 and/or MCP boards.
