MS630-CA Technical Information for MicroVAX 11based systems

DESCRIPTION OF MS630-CA MEMORY MODULE

The MS630-CA memory module, shown in Figure 1, is a standard, quad-height memory module that
contains 8 megabytes of MOS memory storage. It employs 256K x 1-Bit Dynamic RAMs (DRAMS)
in a ZIP (Zig Zag In-line Package) configuration. This packaging allows a two-fold increase (over
conventional DRAM DIP packaging) in the number of DRAMs that can be mounted on the circuit
board. The 8 megabyte array consists of eight blanks, with thirty-six 256K x 1 DRAMs in each bank.
The MS630-CA is a parity memory, and does not perform any error correction. Since parity is
generated. on-board, via parity control logic in the board's data transceivers, errors are detected onboard and reported to the K:A630CPU module ..
The MS630-CA provides the same features and performance (except for capacity) as the MS630-BA
and -AA modules. The MS630 can be used in any combination with other MS630 memory modules,
which provides flexibility in terms of memory configuration for the MicroVAX II. The maximum
physical address space of the MicroVAX II is 16 megabytes. There is one configuration where 17
Mbytes (two MS630-CA modules and the megabyte from the CPU module). Under this configuration,
the megabyte of memory on the KA630-A CPU module is not used.

NOTE:
The PQL_DWSDEFAULT SYSGEN parameter is set incorrectly for most 16 MB MicroVAX II
systems, and will cause the following error message to be displayed every time these systems
are booted: %SYSBOOT _W _WS, default and quota raised to PHD + MINWSCNT. There is
no harm caused due to the low SYSGEN parameter value, and the customer can work around
the error message by raising the value of the PQL DWSDEFAULT SYSGEN parameter. This
parameter will be modified in a futUre release of MicroVMS.
NOTE:
When using the "SHOW MEMORY" utility under MicroVMS, a "BAD PAGE" is indicated
whenever one or two 8 Mbyte memory modules are used in the system. A "PAGE" in
this instance refers to a 512 byte block. When the total system memory equals 13 Mbytes
(one MS630-CA memory module installed), one "BAD PAGE" will appear in response to
the "SHOW MEMORY" command. When the total system memory equals 16 Mbytes (two
MS630-CA memory modules installed), two "Bad Pages (1024 bytes) will be indicated. The

MOM diagnostic used to test the MS630-CA will not indicate these pages as "BAD", but
rather indicates that these pages are "IN-USE" for supporting the console program (thus,
they are not tested by MOM).

INTERCONNECT INFORMATION

The MS630-CA modules interface with the KA630-A CPU through the Micro VAX local memory interconnect in the CD rows of slots 1 through 3 of the backplane, and through a 50-pin cable. This
cable is installed between Jl of the KA630-A CPU and the corresponding connector on one or both
MS630 modules.

ADDRESS, VECTOR, AND SWITCH SETTINGS

No hardware ~ettings are necessary on MS630 memory modules. Memory module addresses are
automatically determined by their position in the backplane.
CAUTION:
MS630-BA and ~BB modules can only be installed in slots 2 or 3. They must NOT be installed
in Q22-Bus slots. MS630-AA modules can only be installed in the CD rows of slots 2 or 3.

CURRENT AND POWER VALUES FOR THE MS630-CA
NOTE:
This section provides the current and power values to be used when configuring a system
which includes the MS630-CA. For information on the values for other components in a
Micro VAX II system, refer to Table 5-4 of the Micro VAX System Maintenance Guide (AZGM3AB-MN).
.

The MS630-CA module draws 2.11 amps of current at + 5V, for a total power consumption of 10.55
watts. The module draws no current at + 12V, nor does it present any AC or DC bus loads.

MOM Tests, Utilities, and Error Messages
Customer Tests

FUNCTIONAL VERIFY-checks bitmap created during power-up diagnostics, fails if bitmap
shows any missing pages.

EXERCISER-Copies bitmap generated during power-up, turns off the interrupt, and turns the bit
for a particular page of memory off, turns interrupt back on, and then exercises the corresponding
memory page. Performs pattern check and check for soft parity error. All accesses to memory
are done through the Q22-bus mapping regIster. When testing for a particular page is completed,
the bit in the bitmap corresponding· to that page is returned to the on position. This procedure
is repeated for each bit in the map.
NOTE:
The exerciser should take no more than 1 minute per megabyte of memory.

Service Tests

NOTE:
All the tests listed in the Customer Tests section above are also available in Service Tests.

8.3

Utilities

NOTE:
Utilities are available only with the Service Version of MOM.

UTILITY #l-performs the same check as the functional verify test, but prints out memory map,
including bad areas, instead of passing or failing.

UTILITY H2-Destroys contents of memory, and performs endless stand-alone memory test (the
same tests as in the power-up diagnostics). Prints summary of test results on 1st, 10th, 20th,
passes, etc.
NOTE:

Once this test is performed, anything needed in system memory (MOM, the operating system, etc.) will have to be rebooted.

When an R054 drive is used as a single fixed-disk drive in a BA23 enclosure, it should be configured
to respond to drive select line 3 (053). This will make the drive ROO.
When R054 drive is used in a BA123 enclosure, drive numbering is determined by the choice of
connectors used on the M9058 distribution board. Provided the M9058 board is set to factory configuraton, jumpers on the R054 drive has no effect.

Current and Power Values for the RD54
NOTE:
This section provides the current and power values to be used when configuring a system
which includes the R054. For information on the values for other components in a Micro VAX
II system, refer to Table 5-4 of the MicroVAX System Maintenance Guide (AZ-GM3AB-MN).

The R054 disk drive draws 1.7 amps at + 5V and 1.57 amps at + 12V, for a total power consumption
of 27.34 watts.
