1.2
There are two main differences between modules used in a BA200-series
enclosure and those used in other system enclosures:
• Modules that connect to external devices have bulkhead handles with
the I/O connector on the handle. The handles replace the insert panels
and internal cabling found
in BA23 and BA123 enclosures. This design
is easier to
maintain since it eliminates problems caused by faulty
internal cabling.
• Modules that do not have external I/O connections (such as memory
modules) have blank bulkhead covers.
The module handles
and blank covers form an electrical noise seal that
complies with requirements for electromagnetic interference (EMI) by
(1) keeping radio frequency interference generated by the system in the
enclosure, and (2) keeping external radio frequencies from entering the
enclosure. The module handles and blankcovers also help guarantee proper
airflow.
Each handle or cover
has two captive quarter-turn Phillips screws to hold
the module in the card cage. Module handles also have release levers to
help install or remove
the module from the card cage.
There four basic types of handles
and covers used for BA200-series
compatible modules (Figure 1-5):
single-width flush handle
single-width recessed handle
single-width blank covers
dual-width blank covers
Between Flush and Recessed Handles
When you use a flush-handle module next to a recessed-handle module, you
must install a metal filler plate (Figure 1-5) between the modules. Without
the filler plate, circuitry on a flush-handle module adjacent to the recessed-
handle module is exposed. The filler plate
(part number 70-2450~1) has
four sets of finger stock that provide an effective chassis ground between
the handles. Flush handles and covers have screw holes at the top and
bottom ofeach side for the installation of this filler plate.

Some modules have special configurations, such as the dual-width panel
with I/O connector for
the KA630 and KA640 CPUs. Table 1-1 describes
common variations.

• Covers a standard Q22-bus module that does
not have external 110 connectors (for exam·
pie, a TQK50).
• Covers an unused slot (slots 2 through 10).
If you install this type of cover nextto a module with a re-
cessed handle, you must add a metal filler plate to main·
tain FCC compliance. See Section 1.2.
Covers backplane slots
11 and 12. The cover has a cutout
at the top for routing cables from (1) an RQDX3 in slot
12,
and (2) a TQK50 module to the mass storage de-
vices mounted above
the card cage.
Used on modules designed for a BA200-series enclo-
sure. The handle is riveted to the module. This style
is
the preferred handle for all BA213 modules with exter-
nal I/O connectors. The CXA16 and CXY08 communi·
cation modules use this type of handle.
Used when a recessed handle would interfere with the
module circuitry or 110 connector. The flush han-
dle is also riveted to the module. The
KNll-
S (a MicroPDP-11 processor) and DEQNA-S Ether·
net controller have flush handles.
For the KA630
and KA650 CPU modules. The cover
is not attached to the CPU.
For the KDJ11-BF CPU module. The cover is not at·
tached to the CPU.
For the KA640 CPU module. The cover is not at·
tached to the CPU.
1.3 Storage Device Area
The BA213 enclosure has a mass storage area above the card cage
(Figure
1~), which can contain a combination of standard 13.3-cm (5.25-
in) mass storage devices. For example, one RF30
and two RF71s can
be installed, for a total disk capacity of 950M bytes. Table
1-2 lists the
maximum number of each type of supported mass storage device.

Mass storage devices Me mounted sideways on shock-mounting hardware.
A sliding
track is attached to the each side of the mass storage device. One
shock-resistant support attaches to the upper part of the mass storage area,
and one attaches to
the bottom of the mass storage area. The supports are
attached by two screws enclosed in rubber shock bushings. This shock-
mounting hardware is different, depending on
the type of device. See
Table 3-3 for the part numbers of the sliding tracks and shock-resistant
supports.
drives face
the rear of the BA213, providing easy access to the
drive signal and power cables. TK-series tape drives face the front of the
BA213.
If you install a replacement drive, you must first remove the skid plate that
is shipped on the drive, then install the shock-mounting hardware.

1.4 Backpl
The BA213 has a 12-s1ot, quad-height backplane (Figure 1-8). The
backplane is a 26.3 x 40.7-cm (11.9 x 16-in) assembly with
24 press-pin
connector blocks. The space between each backplane slot is 2.4-cm (0.95-
in). The backplane's printed circuit board is a one-layer, two-sided etch
board.
All 12 backplane slots are QlCD slots. That is, the AB rows of all 12
slots contain the Q22-bus,
and the CD rows of all slots contain the CD
interconnect.
The backplane is bounded
and cannot be expanded. It supports 32
equivalent ac loads
and 20 dc loads from all the modules installed in the
backplane. An ae load is the amonnt of capacitance a module presents to
a bus signal line. One ac load equals 9.35 picofarads (pt). A de load is
the
amount of dc leakage a module presents to a bus signal line. One dc load is
approximately 105 microamperes (J,1A). The backplane presents 5.6 ac loads
to the Q22-bus.
Aribbon cable connects
the backplane to the signal distribution board. This
cable cal'l'ies
the DCOK., POK., +5 Vdc, and signal ground lines for the DC
OK LED and disk activity lights on the front of the system. The lO-pin
cable connector is on the upper right of the backplane.
The backplane
has two 56-pin edge board connectors. The connector near
slot 1 supplies power to backplane slots 1 to 6. The connector near slot 12
supplies power to backplane slots 7 to 12.
The backplane also
has a 4-pin power connector on the right side for a cable
to the two dc fans below the card cage.
