Hardware Investigation & Repair 5.3
LED Indicators 5.3.1
Test Modulator Board 5.3.1.1
One LED indicator is located on the front panel of the board:
HW
Turns to green and flashes at 1-PPS to show that the hardware is correct.
Unlit (or high rate flashing) in the case of Test Modulator board or CPU board failure.
Demodulator Board 5.3.1.2
One LED indicator is located on the front panel of the board:
HW
Turns to green and flashes at 1 PPS to show that the hardware is correct.
Unlit (or high rate flashing) in the case of Demodulator board or CPU board failure.
CPU Board 5.3.1.3
Refer to Annex 4.
IPMIMonitor Tool. Temperature Alarm 5.3.2
The CPU board has several sensors for monitoring the Pentium processors and board temperature.
These sensors are permanently monitored by a dedicated software tool IPMIMonitor. To run this
software, click on START  PROGRAM  IPMIMonitor  IPMIMonitor.
Check the three following status in the list:
STATUS NAME: TYPICAL VALUE @ 22°C AMBIENT: ALARM THRESHOLD:
Baseboard Temp. 34 °C 52 °C
Processor 1 Temp. 43 °C 72 °C
Processor 2 Temp. 43 °C 72 °C
These alarms are reported to the remote monitoring clients via the Global CORTEX Monitoring table
(Annex 1, STI 100013_<product name>, Table 6, offset 41) and at the CORTEX GUI (bottom status
bar. See section 4.3.5.5 ).
In case of temperature alarm:
 Immediately shutdown and switch off the chassis to avoid any damage to the hardware.
 Verify that the air exhaust system of the housing rack works properly,
 Verify that the air intake and exhaust grids are clear. Important: a free rack space must be
provided above and below the chassis,
 Check the cooling fans on both sides of the chassis, at the rear panel of the chassis (power
supply module) and on both CPU processors.
 Return the chassis to SDSY or its maintenance representative if the problem cannot be fixed on
site.
