System (FMS) Errorsbe received. For example,“FMS error 14” is received. This
means that FILE D is not available for creation, for opening, or for

4.0 Maintenance commands are input via the maintenance
terminal to designate particular parts of the system hardware as
“maintenance busy” so that system software will not try to use
that hardware during system operation. Hardware is out of
service when designated as maintenance busy. That piece of
hardware becomes available for maintenance purposes and can
be physically removed from the system and replaced with a
spare card. This will not cause interruption of service.
The maintenance terminal is also used to place parts of the
system back into service. However, the part is tested by the
system before it is placed back into use. When testing is
completed, the system outputs response codes to any attempts
to place equipment into service. A response code is outputted if
the attempt is successful, or if the equipment fails system testing
and is not placed into service. The responses are an aid to
maintenance and troubleshooting.
4.1 The system does not require regularly scheduled preventive
maintenance. Cabinet cooling is based on natural convection
with no fans or air filters to clean or replace.
4.2 Voltage checks are performed as part of troubleshooting and
are discussed in the TL-130300-1001. Voltage adjustments
are set at the factory and should not be altered as a part of field
maintenance. Battery packs are checked during installation and
are charged by the system.
4.3 System operation checks simply use the standard functions
of the system to ensure proper operation. Checks are usually
performed when installation is completed and, selectively, at the
conclusion of a corrective maintenance action. Refer to 
TL-130100-l 001 for detailed operating procedures when attempting
to make particular types of calls and execute particular system
features.
4.4 Spare cards should be tested for correct operation after the
system is completely tested and operational. To test the spare
cards, replace a working card with an identical spare and test the
feature or function associated with it. Once the function of the
spare has been confirmed, remove it and replace the original.
4.5 Table 2.1 is a listing of the fault codes and functions
associated with the system.M-l 07 
						

							TL-130200-1001Attendant Console4.6 The memory of each CEC provides an area called the fault
Code Display Faultlog which records system faults. It records the last 32 faults
detected. When a fault is detected, the ALARM LED on each
Attendant Console flashes, indicating that a fault has occurred.
Each console displays all faults reported in the fault log
independently of the other consoles in the system. All of the
faults listed on the fault log are displayed by repeated
depressions of the ALARM pushbutton. If all faults have been
displayed at an Attendant Console, an additional depression ofthe ALARM pushbutton causes the station number display to go
off and the ALARM LED to stop flashing, unless a MAJOR alarmexists which will cause the ALARM LED to light steady. A steady
ALARM LED should cause the Attendant to call for maintenance
assistance.
Depressing the ALARM pushbutton associated with the flashing
LED displays a three- or four-digit number in the stationnumber display on the Attendant Console. This display is
interpreted as follows:l The first two digits indicate the fault type. Refer to Table 4.1
l The third digit indicates in which equipment complex the fault
occurred. Refer to Table 4.1.
* If provided, the fourth digit gives additional information. Refer
to Table 4.1.

							TL-130200-1001Fault Code 00Description:
Block Parity FailureWhen a program is loaded into the system, the CPU85 willgenerate block parity for each 256 bytes of instruction data and
static data. This is done by an exclusive OR of the data table.
Periodically, the CPU85 will recalculate the block parity andcompare it with the value calculated earlier (detect memory
failures and data mutilation).

2.Power down - turn off main circuit breaker at rear of OMNI
SI cabinet.
3.Remove and replace Ml MB in Y/01, FB-17314-1A (check
strapping).
4.Power up and reload system - depress reset on PSUPY
card.
5.Monitor PSUPY in P/O1 for ASW LED to light.
6.If fault occurs, power down and reinstall original MlMB card,
and replace the MPG16 card.
7.If fault is still present, read the data for the pre-loading,
memory test (see disk handling and and Fault Code 19) andreplace the Ml MB card.

							TL-130200-1001Fault Code 01Description:
Dynamic RAM MemoryThe system tests dynamic memory. A block of five bytes is put
into a temporary storage area. A series of test patterns is read
into the area of memory being tested and then verified. The data
is returned to its original location and the test advances to the
next five bytes of dynamic memory (interrupts are disabled during
this test).
