GTE Omni Scbs Installation And Maintenance Manual

							RUN LAMP (GREEN): 
. INDICATES NORMAL ON CONDITION. 
. IF OUT, A MAJOR ALARM CONDITION IS INDICATED 
(DISPLAYED AT REMOTE LOCATION) CAUSED BY ONE OF 
FOLLOWING CONDITIONS: 
- POWER OUTAGE, 
- DEFECTIVE CPM OR SWC OSCILLATING CIRCUIT, OR 
- SIXTEENTH FAILURE TO RESTART SYSTEM VIA WATCH- 
DOG TIMER. 
. 6PFT CARD AUTOMATICALLY SWITCHES ITS CIRCUITS TO 
POWER FAILURE TRANSFER MODE. 
ALARM LAMP (RED): 
@ INDICATES A MINOR ALARM CONDITION (REMOTE 
LOCATION) BECAUSE SOFTWARE HAS DETECTED A 
FAILURE IN ONE OR MORE SYSTEM AREAS. 
0 FAULT LOG (CMC-801) LISTS MORE DETAILED 
INFORMATION ON CAUSES OF FAILURE. 
THblE OVERFLOW (TO) LAMP (RED): 
0 INDICATES WATCH-DOG TIMER HAS DETECTED A FAILURE 
IN CPM CARD OR OPERATING PROGRAM. 
0 SYSTEM AUTOMATICALLY ATTEMPTS RESTART AND IF 
SUCCESSFUL, LOGS FAULT IN FAULT LOG. 
0 AFTER 16 UNSUCCESSFUL RETRIES, RUN LAMP IS TURNED 
OFF. TO LAMP MUST BE TURNED OFF BY COLD OR HOT 
RESTART, OR BY READING FAULT LOG.

							Remote Alarm Stat 
CUSTOMER PROVIDED ALARMS AT REMOTE LOCATIONS CAN INDICATE 
ONE OF TWO ALARM STATES: 
MAJOR ALARM - 
. SYSTEM POWER IS OFF AND SYSTEM IS IN POWER FAILURE TRANSFER 
MODE. 
MINOR ALARM - 
. SYSTEM HAS FAILURE IN ONE OR MORE AREAS OF OPERATION. 
IF BOTH ALARMS ARE ON, THE SYSTEM HAS DETECTED A SYSTEM-WIDE 
PROBLEM. 
3.11  
						

							PROGRAMMED ALAlwl BUTTON ON BLF/lxS (OR OTHER DESIGNATED 
MT INSTRUMENT) lNDKATES A MINOR ALARM CONDITION. 
LOCATION OF PROBLEIM A D FAULT LOG LISTING CAN BE OBTAINED 
THROUGH USE OF PIMP OR IVET WITH CIVIC-800 AND 801.

INSTRUCTIONS: THE FOLLOWING EXERCISE CONSISTS OF MULTIPLE CHOICE, TRUE/FALSE, FILL IN 
THE BLANK, OR MATCHING TYPE QUESTIONS. ALL AVAILABLE RESOURCES (I.E., STUDENT WORK- 
BOOK, NOTES, AND GTEP MANUAL) MAY BE USED AS REFERENCES. SUBMIT EXERCISE TO 
IINSTRUCTOR FOR GRADING WHEN LAST QUESTION HAS BEEN COMPLETED. 
1. THE TOOLS REQUIRED FOR SYSTEM DATA BASE MAINTENANCE ARE 
AND 
2. REMOTE MAINTENANCE USING A PORTABLE MAINTENANCE PANEL REQUIRES 
AT BOTH THE REMOTE SITE AND AT THE OMNI SBCS SITE. 
3. LIST THREE PREVENTIVE MAINTENANCE PROCEDURES RELATED TO PROPER CARE OF PCB 
CARDS: 
(4 
4. THE THREE PRIMARY VISUAL INDICATORS OF SYSTEM STATUS ARE: 
A. CPM LED LAMPS, CABLE WARNING SYSTEM, AND MAJOR AND MINOR ALARMS AT REMOTE 
LOCATION. 
B. ALARM BUTTON ON SINGLE LINE TELEPHONE, MAJOR AND MINOR ALARMS AT REMOTE 
LOCATION, AND SYSTEM FAULT LOG. 
C. POWER ON LAMP, CPM LED LAMPS, AND POWER FAIL TRANSFER ALARM. 
D. CPM LED LAMPS, MAJOR AND MINOR ALARMS AT REMOTE LOCATIONS, AND ALARM 
BUTTON ON BLF/DSS OR EKT INSTRUMENTS. 
5. HOW COULD MORE DETAILED INFORMATION BE FOUND ABOUT MINOR ALARM CONDITION OR 
WATCHDOG TIMER OVERFLOW?
