BA214 Enclosure Description
1.1 Introduction
The BA214 enclosure is a member of the BA200-series of enclosures, and
is available in rack mount and wall mount configurations.
The BA214 enclosure has six backplane slots, one power supply, and
one fan. The enclosure does not support mass storage devices; system
diagnostics must be either loaded from the Ethernet or contained on the
CPU module.
Figure 1-1 shows the BA214 enclosure with its major field replaceable units
(FRUs).

1.2 Card Cage and Module Handles
There are two main differences between modules used in a BA200-series
enclosure and those used in other system enclosures:
• Option modules with external I/O connectors have bulkhead handles.
These handles replace the insert panels and internal cabling found in
the BA23 and BA123 enclosures. This design is easier to maintain
because it eliminates system errors caused by faulty internal cabling.
• Non-I/O modules (such as memory modules) have blank bulkhead
covers.
The module handles and covers form an electrical seal that complies with
regulations for electromagnetic interference (EM!) for (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 blank covers also help guarantee proper airflow.
There are four basic types of handles and covers used for BA200-series
compatible modules (Figure 1-2):
Single-width flush handle
Single-width recessed handle
Single-width blank covers
Dual-width blank covers
Each handle or cover has two captive quarter-turn Phillips screws to hold
the module in the card cage (Figure 1-2>. Module handles also have release
levers to help install or remove the module from the card cage.

Some modules have special configurations, such as the dual-width cover
with 110 connector for CPUs. Table 1-1 describes common module cover
variations.

Number Description
70-23981-01 Covers one backplane slot in the following cases:
-
H3600-SA
H3601-SA
H3602-SA
Covers a standard Q22·bus module that does not have ex·
ternal 1'0 connectors (for example, a memory mod-
ule ).
Covers an unused slot (slots 2 through 6).
If you install this type of cover next to a module with are·
cessed handle, you must add a metal filler panel to main·
tain compliance for EM!. See Section 1.2.1.
Csed on modules designed for a BA200·series enclo-
sure. The handle is riveted to the module. This style
is the preferred handle for all BA214 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 I/O connector. The flush han-
dle is also riveted to the module. The KDJl1-
S (a MicroPDP-ll 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 KDJll-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.
1.2.1 Filler Panel for Covers and Flush Handles
When you install a module with a blank cover or flush handle next to a
recessed-handle module, you must install a filler panel (Figure 1-2) between
the modules to meet regulations for EMI. Without the filler panel, circuitry
on the recessed-handle module is exposed. The filler panel has four sets of
finger stock that provide an effective chassis ground between the handles.
Flush handles, recessed handles, and covers have screw holes at the top
and bottom for the installation of this filler panel.

1.2.2 Support Panel for Dual-Height Modules
A plastic panel provides extra support for dual-height modules in the
BA200-series card cage. Dual-height modules are always installed in the
AB rows of a slot. The panel plugs into the CD rows below the module
to provide
additional support. The panel has a fitted groove along the top
edge to support the dual-height module above it.
1.3 Backplane
The BA214 enclosure has a six-slot, quad-height backplane (Figure 1-3).
All six
backplane slots are Q/CD slots. That is, the AB rows of all six
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 amount of capacitance a module presents to
a bus signal line. One ac load equals 9.35 picofarads (pD. A de load is the
amount of dc leakage a module presents to a bus signal line. One dc load is
approximately 105 microamperes (pAl. The backplane presents 5.6 ac loads
to
the Q22-bus.
The backplane (Figure 1-3) has one 56-pin edge board connector mounted
on the left side to connect to the power supply, and one 4-pin power
connector, also on
the left side, for a cable to the dc fan below the card
cage.
1.4 System Controls and Indicators
The baud rate select switch and power-up mode switch are on the dual-
width CPU 110 cover. These controls vary depending on the CPU. Refer
to the applicable CPU maintenance documentation for a description of the
controls on the CPU 110 panel.
The power supply has the following dc power indicators, which light when
the dc voltages are within regulation:
• DC OK LED, located on the control panel
• Green LED, located on the front of the power supply
BA214 Enclosure Description 1-7

1.5 Power Supply
The BA214 enclosure contains one power supply (Figure 1-4). The power
supply plugs directly into the backplane via a 56-pin connector. The power
supply delivers the following maximum current:
7.0 amps at +12 Vdc
33.0 amps at +5 Vdc
The maximum current at +12 Vdc and +5 Vdc must not consume more than
230 watts of power.

An ac line filter provides ac input power to the power supply. The filter is
under the power supply and card cage (see Figure 1-1). The power supply
has a 12-hole (six of which contain connectors) ac input power connector at
its base.
The power supply enters and completes a shutdown sequence (Figure 1-5)
whenever the BPOK H signal is negated. When BPOK H is asserted high
on the Q22-bus, the power system is in a state to allow normal system
operation. The following conditions negate BPOK H:
• Temperature sensor triggered, possibly caused by fan failure
• An overcurrent condition
• Input voltage greater than 132 Vrms or less than 88 Vrms

1.6 Fan
The BA214 enclosure has one 11.3-cm (4.5-inJ dc fan attached to the ac line
filter. The fan draws air into the top of the enclosure, through the card cage,
and out the bottom of the enclosure. A temperature sensor in the power
supply adjusts fan speed by varying the fan's input voltage based on the
room temperature. The sensor adjusts input voltage to provide sufficient
cooling,
at minimum speed, for all combinations of load. The maximum
output is -12 volts at 45°C (113°F). The minimum is -6 volts at 28°C (82°F).
1.7 Configuration Guidelines
Before you change a configuration in the BA214 enclosure, you must
consider the following factors:
Module
order in the backplane
Module configuration
When you add a device to a system, you must know the capacity of the
system enclosure in these areas:
Number of backplane slots
Power limitation
1.7.1 Module Order and Configuration
Module order in the backplane is system specific, depending on the CPU.
Refer to the applicable CPU maintenance documentation for the preferred
module order of the specific system.
For information on how to configure modules, refer to Microsystems Options,
which includes a complete listing of all supported options along with the
following information for each module and device:
Ordering information
Operating system support
Diagnostic support

1.7.2 Configuration Worksheet
Use the configuration worksheet (Figure 1-6) to be sure a configuration
does
not exceed system limits for expansion space, power, and bus loads. If
you use standard DIGITAL modules, you will not exceed the limits for bus
loads.
When you change a configuration, use the worksheet as follows:
1. On the worksheet, list all the devices already installed in the system.
2. List all the devices you plan to install in the system.
3. Fill in the information for each device, using the data listed in
Table 1-2.
4. Add up the columns. Make sure the totals are within the limits for the
power supply.
NOTE: Check the appropriate CPU maintenance documentation to
determine which options are supported for the specific system.
