Position Possible failing item DSA (BBBBCcbb) Unit address
D02, D08 Disk unit xy0200FF (where x is the
same as the first character
of the xFFFFFFF IOA Unit
Address and y is I/O bus 0,
1, 2, or 3. Storage IOA
buses begin with 0 and are
numbered from the tailstock
toward the middle of the
card. Find the storage IOA
with the same DSA and
xFFFFFFF address, then
trace the I/O bus cable to
determine if the position is
D02 or D08.)
D03, D09 Disk unit xy0300FF (where x is the
same as the first character
of the xFFFFFFF IOA Unit
Address and y is I/O bus 0,
1, 2, or 3. Storage IOA
buses begin with 0 and are
numbered from the tailstock
toward the middle of the
card. Find the storage IOA
with the same DSA and
xFFFFFFF address, then
trace the I/O bus cable to
determine if the position is
D03 or D09.)
D04, D10 Disk unit xy0400FF (where x is the
same as the first character
of the xFFFFFFF IOA Unit
Address and y is I/O bus 0,
1, 2, or 3. Storage IOA
buses begin with 0 and are
numbered from the tailstock
toward the middle of the
card. Find the storage IOA
with the same DSA and
xFFFFFFF address, then
trace the I/O bus cable to
determine if the position is
D04 or D10.)
D05, D11 Disk unit xy0E00FF (where x is the
same as the first character
of the xFFFFFFF IOA Unit
Address and y is I/O bus 0,
1, 2, or 3. Storage IOA
buses begin with 0 and are
numbered from the tailstock
toward the middle of the
card. Find the storage IOA
with the same DSA and
xFFFFFFF address, then
trace the I/O bus cable to
determine if the position is
D05 or D11.)
