This manual describes the general specifications, installa-
tion, theory of operation, and maintenance procedures that
apply to the BAll-K mounting box. The basic BAll-K
includes a 10-1/2 inch mounting chassis and power system
that
is similar to the 11/05-S and 11/35-S chassis and power
system. This manual
is also used for maintaining and
troubleshooting the PDP-ll/05-S and PDP-ll/35-S power
system. The manual is organized
as follows:
Chapter 1 describes the characteristics and specifications
of
the BAll-K.
INTRODUCTION.
Chapter 2 describes the system unit configurations, options,
and option guidelines applicable to the BAII-K.
Chapter 3 contains a mechanical description
of the BAII-K
and its contents, and describes the theory of operation.
Chapter 4 describes the BAII-K power system maintenance
procedures, . and the replacement procedures for failed
items.
Chapter 5 details unpacking and BAII-K installation.
