Mitel Sx 200 Ml Pabx Lightware 16 Instructions Guide

							7 Maintenance Controls 
and Indicators 
General 
7.1 The following paragraphs describe the maintenance controls and ir idicators found on 
the components of the SX-ZOO ML PABX. Most of the indicators are 
software-controlled, and provide maintenance personnel with information on the 
current status of the system. 
Main Control Card II 
7.2 There are two variants of the Main Control Card II (MCC II): one with a Stratum 4 
clock, the other with a Stratum 3 clock. The MCC II contains status LEDs, two 
seven-segment display LED indicators, two push buttons, and a slot for a flash 
memory card. These controls and indicators are labelled clearly on the MCC II front 
panel (See Figure 7-l). The functions of the controls and indicators are described in 
the following paragraphs. 
System Reset Button (RESET): When this manual system reset button is pressed, 
the system will cease all activity, run all initialization tests, and reload the software. 
CAUTION: Never press the system reset button while the SX-200ML PABX is 
handling traff ic, because all calls will immediately be dropped, and 
the system will switch to System Fail Transfer mode. 
System Interrupt Button (INTER): When this manual system interrupt button is 
pressed, the system will clear the Random Access Memory on the PC, cease all activity, 
run all initialization tests, and reload the software. The system interrupt button can be 
pressed only when the following conditions are met: 
l The system is within the first ten seconds of the reboot procedure. 
l The top seven-segment LED shows “C”, and the lower seven-segment LED is 
blank. 
Flash Memory Card: The flash memory card containing the system software is insett- 
ed into the slot on the MCC II card, only while power is OFF.

Seven-Segment Display Status Indicators. 
The-MCC II status indicators consist of 
two seven-segment display LEDs that are arranged vertically. The top display LED is 
more significant than the lower display LED. 
The function of the MCC Ii status indicators depends upon the software currently being 
executed. At system initialization, status indicators indicate the status of the MCC II 
tests (seeTable 7-l). During normal operation when no applications are using the status 
indicators, a pair of horizontal dashes are displayed. 
When certain functions are being performed by the system, the status indicators display 
the appropriate codes. These functions and codes are listed in Table 7-l. 
When the maintenance person is accessing the test line facility, the status indicators 
are dedicated solely to this function. Refer to Part 6 of this practice for further details 
on the test line. 
When the system detects an error, the status indicators show the physical location of 
the most recent card to have a problem entered into the maintenance log. The card’s 
bay number (top display LED) and slot number (bottom display LED) will be displayed. 
The status indicator displays do not clear until the user reads or prints the logs of a 
problem area from within maintenance. After the logs are read or printed, the display 
is cleared of all the previous problem areas.

Activity LED. This green LED serves as an indication of the health of the system. A 
steady l-second pulse cycle indicates that the system is up and running. If the LED 
remains constantly on or off, it indicates that the system is not running. In this case 
consult the TrouMesI?ootirrg Practice. 
Alarm Status LED. This red LED is located above the Activity LED. The alarm status 
LED indicates the overall system alarm level. Refer to Part 3 of this practice for further 
information on alarms. The four alarm levels are: 
l NO ALARM - indicates that the system is functioning properly (alarm LED is off). 
l MINOR - indicates that there are problems affecting the system in small proportion 
(alarm LED will flash with a period of 100 ms on, and 900 ms off). 
. MAJOR - indicates that there are problems causing a serious degradation of 
service (alarm LED will flash with a period of one second on, and one second off). 
l CRITICAL - indicates that there has been a very serious loss of call processing 
capability; an automatic system fail transfer (SFT) is invoked and the system is 
reset (alarm LED is on solid).

							General Maintenance Information 
Bay Control Card 
7.3 The Bay Control Card has three status LEDs labelled TX, Rx and ALARM. The TX and 
Rx LEDs indicate communication (transmit and receive) with the Main Control Card Ii. 
The ALARM LED has two functions. A flashing ALARM LED indicates a failure on the 
Bay Control Card. A permanently lit ALARM LED indicates that the Bay Control Card 
is waiting for, or has lost, communication with the Main Control Card Il. See Table 7-2 
for a summary of the Bay Control Card status LED states.

Peripheral Circuit Cards 
7.4 Digital Cards. On a digital card, each circuit has one associated LED which indicates 
the busy (on) or idle (off) status of the circuit. When a digital circuit is removed from 
service by the maintenance system, the associated LED will flash with a period of 0.5 
second on and 0.5 second off. Each digital peripheral card has an alarm LED located 
at the bottom of the card’s front panel. If any circuit on the card has a known fault or if 
a card is installed in an unprogrammed or incorrect card slot, the alarm LED will flash 
with a period of 0.5 second on and 0.5 second off (See Figure 7-2).

Supply (see Figure 7-4). There are two LED indicators located on the front panel of 
the Bay Power Supply; the top LED is the power ON indicator, and the bottom LED is 
the ring generator indicator. The ring generator indicator will flash on only when 
ringing signal is applied.
