Troubleshooting 
Procedures 
Main Control Card II 
4.1 The following paragraphs outline troubleshooting for the Main Control Card Il. 
Configuration 
The Main Control Card II consists of the following: 
l Main Control Card II 
l System ID module 
. Flash Memory card 
l Tl Clock. 
Main Control Card II Power-Up Tests 
The Main Control Card II power-up tests are run automatically upon operation of the 
RESET pushbutton located on the Main Control Card II front panel. The test results 
are indicated in code form on the Main Control Card II’s numeric displays. 
First-Step Checks 
Prior to replacing cards as directed by the Main Control Card II troubleshooting 
procedures, carry out the following checks: 
l Reseat the suspect card. 
l Check for bent pins at the backplane or module connector, as applicable. 
l Power off and power on. 
If the above does not clear the fault, replace the card. 
Power-Up Sequence 
The Main Control Card II diagnostic power-up sequence is described in the Genera/ 
Maintenance hfomation Practice. 
Troubleshooting Procedures 
Troubleshooting procedures for the Main Control Card II are covered under 
“Emergency Troubleshooting Procedures” (Table 2-l). Table 4-l outlines the most 
likely causes of Main Control failure. Figure 4-l shows an SX-200 ML PABX.

Step Possible Malfundion Source for SX-ZOO ML Systems 
1. Main Control Card Ii requires a reset - press IX!ZE~pushbutton on the Main Control Card 
II front panel. 
2. Failure of initialization / power up tests - check for error codes on the Main Control Card II 
numeric displays - see Table 2-2. 
3. Faulty Bay Power Supply - refer to that procedure. 
4. Faulty Main Control Card Il. 
5. Faulty backplane cable connections. 
Note: Useful maintenance commands: SHOW STATUS, TEST, SHOW ALARMS - see the RS-232 
Maintenance Terminal Practice. 
Digital Bay Control Subsystem 
4.2 The following paragraphs detail the troubleshooting procedures for the Digital Bay 
Control subsystem. 
Configuration 
The Digital Bay Control subsystem consists of one card - the Bay Control Card (Part 
No. 9109-017-001). 
Bay Control Power-Up Tests 
The Bay Control Card power-up tests are run automatically upon power-up of the 
associated bay, or a reset of the Main Control Card Il. Failure of any of the power-up 
tests will result in the flashing of the Bay Control Card ALARM LED soon after 
initialization. 
First-Step Checks 
Prior to replacing cards as directed by the Digital Bay Control subsystem 
troubleshooting procedures, carry out the following checks: 
l At the maintenance terminal, SHOW ERRORS and check the DX channel links; 
also check for HDLC errors. Refer to the I%%232 Maintenance Termi& Practice, 
and the Genera/ Maintenance 
hformation Practice. 
l Reseat the suspect card and modules as appropriate. 
l Check for bent pins at the backplane or module connector, as applicable. 
If the above does not clear the fault, replace the modules and card.
