5 MAINTENANCE PROCEDURES
General 5.1
Mechanical Inspection and Cleaning 5.1.1
It is recommended to take the following precautions to get the best performance from the system:
Do not carry out any dust-producing work in the room housing the CORTEX
HDR. Clean the air
filters regularly to avoid electronic components overheating.
Use only alcohol or a water-based cleaner on the front and rear panels of equipment. Other
solvents may damage the keys, LCD and markings.
Perform a regular operating check on the fan units (check for any abnormal temperature rise,
check the air flow at the air exhaust). The system is not designed for permanent operation
without ventilation.
Preventive maintenance: it is recommended to change the Pentium cooling fan every 3 years.
Handling Precautions 5.1.2
WARNING:
SOME OF THE HARDWARE COMPONENTS USE CMOS TECHNOLOGY AND CAN BE DAMAGED
BY ELECTROSTATIC DISCHARGE FROM YOUR CLOTHES OR BODY.
ALWAYS USE AN ANTI-STATIC BRACELET WHEN WORKING ON THE CORTEX
TO REPLACE A BOARD OR COMPONENT.
Never remove a board from the CORTEX HDR without switching it off first and removing the
power cord!
When a module has been removed from the chassis, it is essential to handle and store it with
care. It is particularly important to ensure that it is not exposed to electrostatic shocks.
Certain precautions must also be taken when reinstalling a board in the chassis: when plugging
the board into the PCI bus connectors, never force it; screw the board strip attaching screws
back into the frame; reinstall the connector locking screws. Only then may the CORTEX HDR
be switched back on.
CPU Load Considerations 5.1.3
SDSY DOES NOT WARRANTY CORTEX HDR PERFORMANCE
IF ADDITIONAL SOFTWARE IS LOADED / EXECUTED ON THE MACHINE.
Software Loading 5.1.4
Avoid using floppy disks from unidentified sources. The presence of a virus may severely affect the
performance of the equipment or crash the software.
