Introduction to 3410/3411 MAPs
a service technique that allow~ you to isolate machine
failure ... hy progressing through a flowchart that asks a series of
question" ahout machine performance. Me\PS help isolate failures
quickly without using elaborate test equipment. Based upon your
answer to a specific question, a MAP may direct you to run a
diagnostic program, go to another MAP, replace a failing part
(IRLJ), or take other action to correct the problem .
r<.IAP ... j,
To troubleshoot a problem, start with the Tape Sub~ystem Main
Entry MAP AAO I O. This MAP will direct you to additional MAPs or
diagnostic programs that help to further define the problem.
System/3 diagnostics have numbers in the "700" series. while those
for SySll'm/360 and System/370 are identified as "T34 10 Section".
When two diagnostics are listed, use the one for your system .
'-'
'-
You can also usc the MAPs titles in the 3410/3411 MAPs Listing in
Index L Vol. II to find the appropriate MAP for already-defined
tape unit problems (for example, a circuit protector that keeps
tripping). Always investigate unusual noises and obvious failures
that can lead you direclly to the appropriate MAP .
II you make a mistake following a MAP, or decide you are following
a path that is obviously not related to the problem. don't backtrack,
Rdurn to the Subsystem Entry MAP and start over.

careful lifting it.
Noh.' 8: Many 1\1.\\,., tell you to "power down" before performing
an action. They assume you will "power up" if a suhsequcnt action
require . . you to do so.
SymbolS:
In instances where MAPS fail to define your problem:
Thl' following symbols arc u-;cd in 3410/341 1

2. lnspc~t for loose objects (paper clips, solder, loose wire. etc.) .
3. Check for open land patterns.
4. (,lH~l'k power supply voltages (f()r intermittent failures, use a
VOltmeter having ± O. 25~ accuracy) for level and ripple .

Whenever a field replaceable unit (FRU) change, or
corrective action is specified:
Note I:
I. Power down subsyslem.
2. Rcplacl' ddective f·RU or take corrective action as required,
3. Power up suhsystem and retry failing operation .
NOll' 2:
When more than one component is called out in a
repair/replace block. don't replace all the listed components .
Replace the components one at a time in the order listed, retrying
the failing operatil)n each time until the failing component is found.
Always return unused parts to stock .

Note 4: When replacement or adjustment of a component is called
for, go to the "Checks,Adjustments, Removals. Replacements, and
l.ocations" (C\RRL) section of this manual for correct procedures.
Note 5: When a decision block asks about the status of a certain
byte, that byte will be one of the sense bytes that was printed out
with the error message. The sense bytes are numbered 0 through
K, left to right.
NOll' 6: Some ~\'·\PS ask you to "Check the Cables," In this case,
inspect the conneciOrs for bent or broken pins. repair them. if
necessary, and then reseat the connectors. A continuity check or
check for "shorts" is not required. When a true continuity check is
needed. actual "pin-to-pin" test points are specified .

Note 2 - Lee AnaIy.: Log analysis is a diagnostic
program used to analyze tape error statistics
accumulated by the customer's IBM System Control
Program. The disk system accumulates the statistics on
the disk pack where they can be accessed by the log
analysis program. The basic card system stores the
statistics in core storage until the end of the job, when
they can be punched into cards by the customer. If your
customer is operating with the basic card system, and he
has not punched out the error statistics or saved the
cards, you must, when using log analysis, regenerate
error log data.

Note 4: Applies to S/370 CPU Models 115 and 125 only.
Diagnostic section K, routine 4 or 5 can fail because the tape
u(lit did not recognize a tape mark in the "short tape mark"
recoanition routine. If the customer is interchangulg tapes
with 24XX tape units, install EC.443792 (ECA 044). If the
customer is not interchanging tapes wit~4XX tape drives,
ignore this error and proceed to entry ~

The problem seems to be intermittent. Try looping the diagnostics. A
printol't of the system history records for the suspect tape unit miaht also
prove helpful. Use the error history data in conjunction with MAPs to
analyze the problem.
Erroneous address conditions, which indicate other than the tape unit beina
addressed, generally involve the switch cards in locations OtA1D2 and

1.lIIcIatIoa: An interchangeability problem would be a failure of a

Note 2: To determine if you have an unexpected unit check, scan
down the OL T message until you locate the first "csw RCVD"
flagged with an asterisk that has bit 38 (unit check) on. If the
"csw XPTD" on the line above does not have this bit on, an

Note: Scan the printout for the first unexpected unit check. An
unexpected unit check occurred when the ·CSW RCVD has bit 38
ON and the CSW XPTD does not have bit 38 ON. (See Example
End ofcaU
End of calJ
I.)
The byte and bit notation used in this MAP refers to the sense data
printed out with the error message. In the case of OLT messages,
the reference is to the sense received (SNS 00-08 RCVD) line of the
message. Bits are counted 0-7, left to right. 3410/3411 sense bytes
are numbered 0-8. left to right. (See Example 2,)
Discussion: To prevent the creation of tapes that may not be interchangeable
with 24xx series tape units. the 34 J J models I and 2 are equipped with a
velocity rate of change per bit detection circuit. This circuit is active only in
the PE mode during a write operation.
When the error threshold is exceeded, a Data Check with a Irack.in-error(TIf..
byte 01 will occur. If a tape unit is experiencing a large number of Data Checks
on track 7 (TIE 01) during a write operation. suspect a velocity rate of change
problem.
,Bits 36-39
Common causes of a velocity rate chaRge error are:
1- Lower tape guide in the left column (model I only) has a binding roller.
Check the roller for free rotation. It is important that all washers and
springs are properly instaUed. Refer to CARRL D·24 for correct
installation.
2- Check for column flatness on models I and 2. Excessive warpage of the
vacuum column can cause excessive vibration at the tape loop. Flatness
of the vacuum column in the tape loop area should be checked using a
straight edge. (The edge of the half column cover. PN 2S 17722. can be
used for this measurement.) Column should be flat within 0.015 inches
(0.381 mm) over the area below the BOT/EOT block the full width of
the column.

Dete Check
~: Use this MAP to analyze failures in the tape control
read/write data path.
Types of errors are: "read" or "write" data checks, and equipment
checks set as a result of bad "gating" lines or "hot" bits in the data
path.
Note 1: Cards AIH2, J2 and K2 have the same part number.
When these three cards are called out it should be necessary to get
only one new part. Replace the cards one at a time and retry until
the failing card is replaced.
When interchanging' A-A 1H2, A-A 1J2, and A-A 1K2, refer to ALD
page A6001 for plugging instructions. All three cards should be
factory plugged, as position "K" is model sensitive. If they are not
plugged, refer to the above ALO page.
Note 2: Card OIA-A 102 is used by tape units 0-3 and card
OIA-A1E2 is used by tape units 4 and 5. These cards may be
interchanged for problem isolation. They can cause failures on one
or more tape units.

Discussion: Use this MAP to isolate tape unit data path
problems by using the special LWR (loop-write-I.o-rcad)
test card and OLT section T34100. See MAP AA054 for
procedure. Because the paths for data and sense are the
same, it is possible for failures in this area to cause both
data checks and equipment checks.

pins and land pattern on the card provide tht necessary

crossover to loop Bus Out signals back to the Bus In
cable. You must ensure that the cables are correctly
oriented so that pin B02 of both cables is at the top.
If you came here from MAP AA052, sockets J and K
become Land M, and the signal is looped from socket
L to socket M of the planer. It is not necessary to
plug the Read/Write cables into the card.

Discussioa: Since OLT Section "A" tests NRZlloop··write-to-reau
after testing PE loop- write-to-read, this MAP assumes that PE
loop-write-to-read is working. If PE LWR failed, you would get an
AOS02 message and should go to MAP AAOS t. It is possible that
an intermittent failure could have passed PE LWR and failed on
NRZ L WR. If the action on this MAP does not resolve the
problem, go to MAP AAOS 1.

Discussion: Since skew and tracking are interrelated. you are
asked to verify that tracking is correct before proceeding with skew
checks (AA072). The sequence is as follows:
t. Tracking
EXT - T
2. Mechanical skew.
EXT - M T3410P
3. Electrical skew (forward).
EXT-F EXTERNAL
4. Electrical skew (backward).
EXT-B OPTIONS
5. Electrical skew (write).
EXT-W
A tape unit that does not have the dual density feature does not
have electrical skew adjustments.
Message "XP0044" requests removal of the dual density jumper on
tape unit logic board for EXT-T /M. Reply "0" when removed. For
EXT=F/B/W, plug dual density jumper. Reply "0" when plugged.
Message "XPOOt I" requests the master skew tape mounted on tested
tape unit for EXT-T/M/F/B. Reply "M" when mounted. For EXT-W.

1. Make sure that the system recognizes the tape unit addressed by the customer's program as an
existing tape unit, and that the tape unit is also READY and has been enabled (via the
ENABLE/DISABLE switch). Go to MAP AA112-B4 for reference information.
2. If the tape unit loads but fails to reach READY when the START key is pressed, go to MAP AB090.

DIscussion:
I. Adapter Checkout: After error saving is performed
automatically, the adapter checkout takes place. During the
checkout, data: ~ent from SVP (via SVP Data Bus 0) to the MTA.
The data is set in Lm't Data Reg or Hi Data Reg and sensed back
to the SVP. The SVP compares the data sent against that
received. In case of unequal compare, the 'is' and 'should be'
pattern is saved. If the result is equal, a zero pattern is forced in
both bytes and in the 'data reg' byte.
2. TCU Checkout: After the adapter checkout takes place, the
TCU's initial checkout routine is invoked by an SVP CTRL ·CO'.
After waiting until the routine is performed, ATI-6 (error) is
checked again by the SVP SNS 'CO'. If ATI-6 is active, this
indicates a TCU malfunction and, therefore, the ABI is saved
again and 'Ff' is set into the check byte. If ATI-6 is inactive, the
ATI is investigated for MSC failure (ABI-S).

ENABLE/DISABLE
This switch allows the subsystem to be taken offline for
maintenance. The switch setting can be changed at any time. but
the subsystem changes status only when the system is stopped.
The switch must be set to the DISABLE position to take the
subsystem offline. A disabled subsystem is non-existent to the
system program
To disable (or enable) the subsystem, proceed as follows:
I.
Turn the ENABLE/DISABLE switch to the DISABLB (or
ENABLE) position.
2.
Press STOP and then START at the system console. The
subsystem is now offline (or online).
Usage Meter
~
A time meter on the 3411 records the elapsed time that the tape
control is in use. The meter runs whenever the subsystem is
enabled (online) with the ENABLE/DISABLE switch, and the host
system is operational.
A time meter on each 3410 records only the time that the Cape is in
use. The meter runs whenever the subsystem is enabled, tape is
away from load point. and the host system is operational.

area. The meter should read approximately 3.5 volts. Now move
the BOT marker into the sensing area; the meter should now read
approximately 5.0 volts. If the voltage does not change, connect
the + lead to the other pin of the two-wire plug and repeat the
procedure.

DbcassIon: You must read this entire page before proceeding so
that you und-.:rstand the procedure. This MAP checks operation of
the reel motors, reet control circuits, and pneumatic system during
a LOAD op,·raticn. You must press LOAD/REWIND, verify
presence of vacuum at the column control ports, and observe risht
and left reel mO&io~. Then, you must press RESET and again
observe reel motion. All this must be completed within five
seconds from the time you press LOAD/REWIND. If you cannot
complete the procedure, you must restart the' check, as the
pneumatic system shuts off and the LOAD or UNLOAD cycle is
lerminated after approximately len seconds.

To disable the interlock switch, raise tape transport and reach
behind and abov~ the right reel motor through a hole in the
casting until you can feel the switch. Push the plunger until it
locks. The plunger releases aut('matically when you close the
sliding door (see CARRL 0-6,.

File Protect Failure
~:~ Not. ~
DiseussIon: The file protect (FP) switch is actuated by the write
enable ring in the tape reel. The switch plunger is then held down
by vacuum to keep it from rubbing on the write enable ring. The
plunger should stay down until the vacuum pump stops, even if the
reel with its write enable ring is removed. If vacuum does not hold
the plunger down, vibration caused by the plunger rubbing on the
write enable ring may cause the switch to transfer intermittently.
~
•E'MAP AAO'Y
Note: To make the checks on this MAP, mount a reel with a write
enable ring on the left reel hub. Do not load the tape unit.

starting this MAP. Keep the CARRL section open to Figure 0-3 for reference to this
MAP to perform the tape loop check •
If the completion of "Load Op" is unsuccessful and tape dump has occurred in the right
column. check the capstan for proper sequencing i'lcl"ding LP search. If capstan
appears to run away in a forward direction. go to MAP AB131·A2 and check the
tachometer. Iftac:hometer is OK. return here and continue on this MAP. If it is not

Tran8former T1 Overload
Discussion: Entry to this MAP assumes that either CB I
or CPI keeps tripping, and following MAP AC030,
AC032, or AC050 hasn't corrected the problem.
A defective transformer (T I), or a faulty dc power supply
could cause this condition.
Note: Your problem appears to be ,-=aused by overloading
I
transformer TI. Since diagnosis from this point may be
difficult, you should probably call for assistance, and
check the following while waiting for help:
A. Try replacing CB I or CP I if it has not already been
replaced.
B. Carefully inspect the two circuit boards in the dc
section. Look for anything that might short to the metal
cover.
C. Further diagnosis requires isolating the loads on T I.
While individual dc regulators can be isolated. isolating a
given load may cause CB I or CPt to stop tripping even
though the regulator is not the one causing the overload.
Try replacing T I and the dc circuit boards.

DiIctBtIon: Entry to this MAP assumes that de power supply fuse
A2F2 is blown, causing loss of +6 vdc at DC TB I. Possible causes
are: faulty power supply, regulator card, or dc distribution in the
tape control or in one of the attached tape units.
Note:
A. +6 volts is supplied by power supply A2. This supply is located
on a large printed circuit board at the left side of the dc section.
B. See ALD page YO 160 for component locations.
C. See ALD page YG 110 for circuit diagram.
D. The trouble shooting procedure outlined here may require you
to replace fuse A2F2 several times, so be sure you have several
spare fuses on hand.
E. Allowable ripple must not exceed ±2.S%.

Note:
A. Make the checks called for in this MAP on the tape unit that
caused fuse A2F2 to blow.
8. The +6 volts in the tape unit is distributed from the 3411 J plug
to DC TB 1-9 (+6) and TBI-4 (dc common).
C. From DC TBI-9 +6 volts goes to the capstan tachometer
assembly, the BOT/EOT block, and TB4-S. (TB4 is below the
upper base, to the right of the capstan motor).
D. TB4 terminals are numbered front-to-back.
E. +6 volts goes to TB4-S. then to the file protect switch and. in the
3410, to the meter relay card (adjacent to the meter).
In the 3411 the +6 to the meter relay card comes from tape control
TB2-2.
F. When the FP plunger is pressed, +6 volts is applied to TB4-2. and
from there to the head read/write head card.

Discussion: To prevent the creation of tapes that may
not be interchangeable with 24xx series tape units. the
3411 models I and 2 are equipped with a velocity ratc of
change .per bit detection circuit. This circuit is active only
in the PE mode during a write operation.
No
~.
,....
When the error threshold is exceeded, a Data Check with
a track-in-error (TIE) byte 01 will occur. If a tape unit is
experiencing a large number of Data Checks on track 7
(TIE 01) during a write operation. suspect a velocity rate
of change problem.
Common causes of a velocity rate change error are:
I-Lower tape guide in the left column (model I only)
has a binding roller. Check the roller for free rotation. It is important that all washers and springs are
properly installed. Refer to CARRL D-24 for correct
installation.
2 - Check for column flatness on models 1 and 2. Excessive warpage of the vacuum column can cause
excessive vibration at the tape loop. Flatness of the
vacuum column in the tape loop area should be
checked using a straight edge. (The edge of the half
column cover. PN 2517722. can be used for this
measurement.) Column should be flat within 0.0 15
inches (0.381 mm) over the area below the
BOT/ EOT block the full width of the column.

DIseaIsIoft: The BOT and EOT lamps can be checked visually.
The capstan tach lamp is mo"e difficult to check since it is
mounted on the capstan motor. A tach lamp failure bringS up
DEVICE RESET which disables the LOAD, REWIND, and
UNLOAD functions of the tape unit. A BOT or EOT lamp failure
does not force DEVICE RESET.

Discussion: Tracking and skew adjustment must
be made if the read/write head assembly, columns,
or guides are replaced. Order of adjustment is:
tracking, mechanical skew, read forward skew,
read backward skew, and write skew. Clean the

checks and adjustments.

checked tracking visually (see CARRL Figure 0-36) and
that diagnostic section 70A is loaded and ready to run.
Tracking adjustment should meet requirements specified
by CARRL Figure 0-36, Step 9. The tracking printout
of Section 70A should indicate minimum tracking shift
between forward and backward tape motion.

DiswssIoII: You should enter this MAP if the Log Analysis
program called out the read/write head assembly as suspect, or
because you had a data check and a loop-write-to-read command
did not fail. Be sure that the data check was not caused by
defective tape. Try more than one tape reel.

DIScussion:
I. If the problem is intermittent and you ha~e more than one TU
on your system, consider interchanging the logic board and/or
motion control board with another tape unit.
2. Use only the failing TV for analysis.
3. If this is a single tape unit system and the action called for by
this MAP does not resolve the problem, go to MAP AOOIO if you
have failures running Section 70 I. and to MAP AD020 C I if you
have failures running Section 702.

Note 3: Scan the "Summary of Tape Error Statistics By Tape Unit"
to find any tape unit having a high ratio of errors to ~(art I/Os.
Then look at the "Detail Tape Error Statistics by Tape' Unit" for any
unit that has a higher-than·,average error ratio to get <-i detailed
listing of errors that oc,,:urred on the suspect tape unit. For
instance. high error counts in the "Temp Read Backward" and
"Envelope Check" columns could furnish the symptoms to be
analyzed by using MAP A0076 (Data Check). If Y0U suspect tape
control problems because more than one tape unit has a high error
count, go to MAP AD031 and try to analyze your prohlems on the
basis of error counts. TIE data. etc.
If you have a single tape unit system. try to analyze the prublem as
a tape unit failure hefore looking for tape control prohlems.
