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 blank covers 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 recessedhandle 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 of each side for the installation of this filler plate.

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 next to a module with a recessed 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 devices mounted above the card cage.
Used on modules designed for a BA200-series enclosure. The handle is riveted to the module. This style
is the preferred handle for all BA213 modules with external 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 handle is also riveted to the module.
The KNllS (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.

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 (5.25in) 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 shockmounting 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.
Figure 1-7 shows RD and TK drives with BA200-series sliding tracks.

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 (0.95in). 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.
A ribbon 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.

You must install a load module in one of backplane slots 7 through 12 if
the continuous minimum current drawn on the second power supply is less
than 5 amperes_ If the minimum current of 5 amperes is not reached,
the power supply enters an error mode and shuts down the system. See
Table 1-7 and the configuration worksheet (Figure 1-21).

The BA213 enclosure has the following controls and indicators on the front
panel:
•

On/off power switch with ac power LED

•

DC OK LED

•

CPU halt button

•

Disk drive controls and indicators (system dependent, described below)

The BA213 also has two system reset buttons, one on each power supply.
See Figure 1-1.
NOTE: BA213 enclosures containing RD-series drives, and some BA213
enclosures containing RA-series drives do not have a halt button. To halt
a Micro VAX CPU in such a system, set the enable I disable switch on the

H3600-SA CPU I I 0 panel to enable, and use the break key on the console
keyboard.
Some of these system controls and indicators are mounted on the front
panel, behind a smoked plastic window. The panel has a 3-position lock
that detel mines which controls you can access. You can lower the window
by tmning the lock's universal key to position 2 or 3 (Figure 1-9). The level
of access is as follows:
1. No access to controls. Disk, tape drive, and DC OK LEDs are visible.
2. Access to disk drive and tape drive controls.
3. Access to on/off power switch and latch to remove or open front door.

Mass storage devices receive power through a 9-pin MTA connector on
the top front of each power supply. Each power supply also has a power
indicator, system reset switch, and circuit breaker on the front.

The power supply enters and completes a shutdown sequence (Fig\li'e 1-18)
whenever the BPOK H signal is negated. When BPOKH is asserted high
on the Q22-bus, the power system is in a state to allow nOI mal system
operation. The following conditions negate BPOK H:
Temperature sensor triggered, possibly caused by fan failule
An overcullent condition
Input voltage greater than 132 VI illS or less than 88 VI JOs
BPOK H and BDCOK H are parallel. If one power supply stal'ts to shut

Installation
This chapter contains the procedure for installing the BA213 enclosure in
a pedestal. Refer to the H9644 Cabinet Maintenance (EK-221AA-MGJ for
site preparation considerations for the BA213 in an H9644 cabinet.

2.1

Con

2.1.1 Physical Dimensions, BA213 in Pedestal
Figure 2-1 shows the dimensions of the BA213 in a pedestal, and its
shipping carton. You must leave at least 61 cm (24 in) of clearance in
front of the system, for access to system controls. You must also leave at
least 5 cm (2 in) of clearance at the sides and rear, for airflow. Since the
of the enclosure is 5 cm (2 in) wider than the cabinet in front and rear,
you can place the rear of the system against a wall or table, and the system
will have enough room for adequate airflow.
CAUTION: Due to the weight of the equipment, DIGITAL recommends that

at least two people handle the system and tel'minal boxes.

2.1.2 Additional
Make sure there is enough space for terminals and other peripheral
equipment. The temperature and humidity at which mass storage media
are kept should be the same as that of the computer area.
When you plan the cable routing for multiple-tel'minal systems, consider
factors such as safety, convenience, future expansion, and cost. Cabling
should be in place and labeled before you install the system.

2.1.3

Electricity .

Static electricity can cause system failure and loss of data. 'lb minimize
static buildup, follow these guidelines:
•

Maintain relative humidity of at least 40%.

•

Place the system away from busy office conidors.

2-2

BA213 Enclosure Maintenance

I
•

Avoid using carpeting in the computer alea, if possible. If CSl'peting is
to be installed, recommend antistatic carpeting. If carpeting is
in place, place an antistatic mat under the system.

2.1.4 Acoustics
The BA213 in a pedestal is designed for use in offices and other general
working areas. The following are acoustic emission and heat dissipation
levels for the BA213 in a pedestal. Levels may be lower, depending on the
kind and number of mass storage devices in the system. Data is measmed
in accordance with ANSI S12.10-1985 (American National Standards
Institute) and ISOIDIS 7779 (International Standards Organization).
•

LNPE (B) is the noise power emission level (A-weighted sound power
level) measured in bels re 1 pw (reference 1 picowatt). LNPE for the
BA213 enclosure is 5.8.

•

LPA is the sound pressure measured in decibels at 1.0 m from the front
edge of the unit and 1.5 m above the floor. LPA for the BA213
is 43.

2.1.5 Heat

2.4.1 Setting Controls on the System

The controls you must set to complete the installation vary, depending
on the CPU and type of disks in the enclosure. Generally, you must set
the baud rate of the console serial line to the same baud rate as the
console terminal, and be sure the fixed disk drives are ready and not
write-protected. In addition, if the system is a MicroVAX, you must set
the enable/disable and power-up mode switches.
Refer to the system customer documentation for detailed instructions on
setting these controls for the particular system you are installing.

2.4.2 Connecting the Power Cord
Feed the power cord under the system from the rear or the left, and attach

BA213 FRU Removal and Replacement
This chapter describes how to remove and replace the field replaceable units
(FRUs) in the BA213 enclosure.
The following sections desclibe the removal procedui'e for each FRU. Unless
otherwise specified, you can install an FRU by reversing the steps in the
removal procedure.
System-specific FRU procedures vary slightly.
As a result, some
illustrations of system-specific procedures show an example of a FRU
removal. The variations are noted in the text and in the title of the
illustration.
CAUTION:

•

Only qualified service personnel should remove or install FRUs.

•

Before you remove or install FRUs, power down the system.

•

Static electricity can damage integrated circuits. Always use a grounded
wrist strap (part number 29-11762-00) and grounded work
when working with the internal parts of a computer system.

The BA213 uses two types of modules, with or without BA200-series
compatible handles (Section 1.2). Modules designed for BA200-series
enclosures have wide handles that provide both external va connections
and an electrical and environmental seal for the card cage. Standard Q22bus modules that are also used in other enclosures, such as the RQDX3, use
a blank cover instead of a handle. There is a different removal procedure
for the two types of modules. Module numbers are on the handles or the
